The Hauser Report: Oscar Valdez, Phentermine, and the Larger Issue

On September 10, Oscar Valdez successfully defended his WBC super-featherweight title with a twelve-round decision over Robson Conceicao in a bout contested under the auspices of the Pascua Yaqui Tribe in Tucson, Arizona.
That’s the short version of what happened. The long version is more complicated.
After their fight was signed, Valdez and Conceicao enrolled in the Voluntary Anti-Doping Association (VADA) drug-testing program. Top Rank, which promotes both fighters, forwarded their paperwork to VADA and contracted to pay for the VADA testing. This was in addition to the fighters’ mandatory participation in the World Boxing Council Clean Boxing Program (CBP).
In late-August, a urine sample taken by VADA from Valdez tested positive for phentermine – a prescription medication used as a stimulant and appetite suppressant. The use of phentermine is classified by VADA as prohibited at all times.
VADA does not adjudicate performance enhancing drug matters. It tests fighters and reports its findings to contractually mandated parties. In this instance, after receiving the test result, VADA notified Top Rank, the World Boxing Council, and the Pascua Yaqui Tribe commission of the adverse finding.
Athletes rarely say, “I was using a PED and you caught me.” Valdez didn’t either. “What I can say,” he told Mark Kriegel of ESPN, “is that I’m a hundred-percent clean fighter. I don’t know how that got into my body.”
Patrick English (the attorney who represents Valdez) voiced the view that herbal tea, innocently ingested, was the most likely source of the phentermine and that various supplements Valdez took during training are being tested for any hint of contamination. He further noted that only a trace amount of phentermine was found in Valdez’s system and that all other blood and urine samples taken from Valdez by VADA tested negative.
Those arguments aren’t persuasive. Victor Conte (the nutrition and conditioning guru whose involvement with PEDs decades ago is a matter of record) states, “There is no connection between any herbal tea and phentermine in terms of molecular structure. No tea has ever been reported as being contaminated with phentermine. Ever in history. If you google ‘herbal tea phentermine,’ a company called their product by this name as a marketing ploy. But there’s not a shred of credible evidence I’m aware of to support the notion that phentermine is present in herbal tea. There has never been a positive test associated with any herbal tea. There is zero connection between herbal tea and phentermine.”
Conte also makes the point that, in today’s world of micro-dosing, drugs quickly leave a fighter’s system. All a negative test result means is that a fighter was clean on a particular day.
But Valdez had an ace in the hole. For purposes of drug testing, athletes are considered either “in competition” or “out of competition.” In competition begins at 11:59 PM on the night before an event.
When fighters enroll in VADA, they’re told that VADA has one prohibited list and that it doesn’t distinguish between in competition and out of competition drug use. Thus, VADA classifies phentermine as a prohibited substance at all times.
But – and this is a big but – while phentermine is banned in competition under the World Anti-Doping Agency code, its use out of competition is not prohibited by WADA.
Adjudication of Valdez’s case was left to the Pascua Yaqui Tribe Athletic Commission (which had jurisdiction over the fight) and the World Boxing Council (whose title belt was at stake). There was one hearing overseen jointly by both organizations. The tribal commission opted to follow the WADA standard and allowed the fight to proceed without punishment of any kind. The WBC’s position was a bit more complicated because the WBC Clean Boxing Program is, in theory, guided by VADA standards and the use of phentermine – even out of competition – is a violation of the CBP.
However, WBC president Mauricio Sulaiman found a way around this inconvenience, declaring, “This substance [phentermine] does not give you any competitive advantage. It is the equivalent of having three energy drinks.” Sulaiman also noted that only a trace amount of phentermine was found in Valdez’s system.
The WBC then ruled that it would officially sanction Valdez-Conceicao as a title fight. But at the same time, it placed Valdez on probation for twelve months. In addition, Valdez was ordered to take part in and pay for several unspecified educational programs, undergo an unspecified number of random drug tests, and make a minimum of six personal appearances as a WBC Ambassador to promote and educate others with regard to principles consistent with clean boxing.
The WBC ruling ruffled a lot of feathers. Victor Conte is among its foremost critics.
“I’ve given phentermine to athletes in the past,” Conte says. “I know what it does. It’s a powerful central nervous system stimulant and one of the most effective PEDs a boxer can use. It increases heart rate and enables the heart to pump more oxygen to muscle tissue which delays the onset of fatigue and helps increase speed, strength, and stamina. It also suppresses appetite and burns calories to help with weight loss. And its use can lead to serious heart problems. Athletes in other sports are suspended for using phentermine. A player in the NBA [Lindsey Hunter] was suspended after he tested positive for phentermine. Jockeys in horse racing are suspended if they use phentermine to cut weight.”
Why does WADA allow for the use of phentermine out of competition if it has the performance-enhancing and dangerous qualities that Conte says it does?
“Let’s get real about this,” Conte answers. “First, WADA’s protocols were put in place with an eye toward protecting sponsorship dollars. Too many adverse test results are bad for business. And second, WADA’s protocols aren’t designed for boxers. If a stimulant is on the banned list on fight night and you acknowledge that it enhances performance, why would it be legal in training camp? Does this mean that someone can use all the phentermine they want up until the day of a fight? That would be dangerous and allowing it to happen would be negligent.”
“When Oscar Valdez signed up for VADA testing,” Conte continues, “he agreed to follow VADA’s protocols, which include not using phentermine in or out of competition. The WBC didn’t want to lose its sanctioning fee. The tribal commission didn’t want to lose the money that would come in from Valdez-Conceicao and future fights. It’s as simple as that.”
In 2018, Billy Joe Saunders tested positive for the stimulant Oxilofrine, which (like phentermine) is allowed by WADA “out of competition” but is on VADA’s prohibited list at all times. Saunders claimed that the Oxilofrine came from a nasal spray. The Massachusetts State Athletic Commission denied him a license to box and his planned WBO title defense against Demetrius Andrade was cancelled.
“It is the classic case of rules in one place count for nothing in another,” Boxing News editor Matt Christie writes. “The problem lies with a complete lack of uniformity across the governing and sanctioning bodies. Even more problematic is that the sanctioning bodies appear to pick and choose what rules suit them on a particular day.”
Christie is right. There are too many variables. Is there PED testing for a given fight? Which tests? Which commission has jurisdiction over the fight. Who’s administering the tests? Is a sanctioning body involved? To cite one example of an absurd situation, human growth hormone and EPO are still not on the New York State Athletic Commission’s list of banned substances.
In so far as phentermine is concerned, California State Athletic Commission executive director Andy Foster says, “The California State Athletic Commission views the use of phentermine out of competition in the same way as the World Anti-Doping Agency. Phentermine is not a banned substance out of competition by WADA, so it is not banned by the CSAC either.”
Nevada State Athletic Commission executive director Bob Bennett says that Nevada also adheres to the WADA list.
Does this mean that Tyson Fury, Deontay Wilder, Canelo Alvarez and Caleb Plant can use all the phentermine they want prior to their upcoming fights in Las Vegas as long as it isn’t in their system on the day of the fight?
“Not exactly,” Bennett answers. “Phentermine is a prescription drug so, if a fighter uses phentermine, he must declare its use on a pre-fight form and answer questions as to where he got the prescription and why he’s taking it.”
I don’t know what Oscar Valdez did and didn’t do. I do know that most of the moneyed interests in boxing couldn’t care less about protecting the health and safety of fighters except to the extent that they’re protecting their own financial interests. Clean fighters have to stand up and take control on this issue. As part of their effort, they should demand one national standard.
As Andre Ward stated during ESPN’s coverage of Valdez-Conceicao, “We can’t keep moving the goal posts.”

Ringside at the Fontainebleau where Mikaela Mayer Won her Rematch with Sandy Ryan

LAS VEGAS, NV — The first meeting between Mikaela Mayer and Sandy Ryan last September at Madison Square Garden was punctuated with drama before the first punch was thrown. When the smoke cleared, Mayer had become a world-title-holder in a second weight class, taking away Ryan’s WBO welterweight belt via a majority decision in a fan-friendly fight.
The rematch tonight at the Fontainebleau in Las Vegas was another fan-friendly fight. There were furious exchanges in several rounds and the crowd awarded both gladiators a standing ovation at the finish.
Mayer dominated the first half of the fight and held on to win by a unanimous decision. But Sandy Ryan came on strong beginning in round seven, and although Mayer was the deserving winner, the scores favoring her (98-92 and 97-93 twice) fail to reflect the competitiveness of the match-up. This is the best rivalry in women’s boxing aside from Taylor-Serrano.
Mayer, 34, improved to 21-2 (5). Up next, she hopes, in a unification fight with Lauren Price who outclassed Natasha Jonas earlier this month and currently holds the other meaningful pieces of the 147-pound puzzle. Sandy Ryan, 31, the pride of Derby, England, falls to 7-3-1.
Co-Feature
In his first defense of his WBO world welterweight title (acquired with a brutal knockout of Giovani Santillan after the title was vacated by Terence Crawford), Atlanta’s Brian Norman Jr knocked out Puerto Rico’s Derrieck Cuevas in the third round. A three-punch combination climaxed by a short left hook sent Cuevas staggering into a corner post. He got to his feet before referee Thomas Taylor started the count, but Taylor looked in Cuevas’s eyes and didn’t like what he saw and brought the bout to a halt.
The stoppage, which struck some as premature, came with one second remaining in the third stanza.
A second-generation prizefighter (his father was a fringe contender at super middleweight), the 24-year-old Norman (27-0, 21 KOs) is currently boxing’s youngest male title-holder. It was only the second pro loss for Cuevas (27-2-1) whose lone previous defeat had come early in his career in a 6-rounder he lost by split decision.
Other Bouts
In a career-best performance, 27-year-old Brooklyn featherweight Bruce “Shu Shu” Carrington (15-0, 9 KOs) blasted out Jose Enrique Vivas (23-4) in the third round.
Carrington, who was named the Most Outstanding Boxer at the 2019 U.S. Olympic Trials despite being the lowest-seeded boxer in his weight class, decked Vivas with a right-left combination near the end of the second round. Vivas barely survived the round and was on a short leash when the third stanza began. After 53 seconds of round three, referee Raul Caiz Jr had seen enough and waived it off. Vivas hadn’t previously been stopped.
Cleveland welterweight Tiger Johnson, a Tokyo Olympian, scored a fifth-round stoppage over San Antonio’s Kendo Castaneda. Johnson assumed control in the fourth round and sent Castaneda to his knees twice with body punches in the next frame. The second knockdown terminated the match. The official time was 2:00 of round five.
Johnson advanced to 15-0 (7 KOs). Castenada declined to 21-9.
Las Vegas junior welterweight Emiliano Vargas (13-0, 11 KOs) blasted out Stockton, California’s Giovanni Gonzalez in the second round. Vargas brought the bout to a sudden conclusion with a sweeping left hook that knocked Gonzalez out cold. The end came at the 2:00 minute mark of round two.
Gonzalez brought a 20-7-2 record which was misleading as 18 of his fights were in Tijuana where fights are frequently prearranged. However, he wasn’t afraid to trade with Vargas and paid the price.
Emiliano Vargas, with his matinee idol good looks and his boxing pedigree – he is the son of former U.S. Olympian and two-weight world title-holder “Ferocious” Fernando Vargas – is highly marketable and has the potential to be a cross-over star.
Eighteen-year-old Newark bantamweight Emmanuel “Manny” Chance, one of Top Rank’s newest signees, won his pro debut with a four-round decision over So Cal’s Miguel Guzman. Chance won all four rounds on all three cards, but this was no runaway. He left a lot of room for improvement.
There was a long intermission before the co-main and again before the main event, but the tedium was assuaged by a moving video tribute to George Foreman.

William Zepeda Edges Past Tevin Farmer in Cancun; Improves to 34-0

William Zepeda Edges Past Tevin Farmer in Cancun; Improves to 34-0
No surprise, once again William Zepeda eked out a win over the clever and resilient Tevin Farmer to remain undefeated and retain a regional lightweight title on Saturday.
There were no knockdowns in this rematch.
The Mexican punching machine Zepeda (33-0, 17 KOs) once more sought to overwhelm Farmer (33-8-1, 9 KOs) with a deluge of blows. This rematch by Golden Boy Promotions took place in the famous beach resort area of Cancun, Mexico.
It was a mere four months ago that both first clashed in Saudi Arabia with their vastly difference styles. This time the tropical setting served as the background which suited Zepeda and his lawnmower assaults. The Mexican fans were pleased.
Nothing changed in their second meeting.
Zepeda revved up the body assault and Farmer moved around casually to his right while fending off the Mexican fighter’s attacks. By the fourth round Zepeda was able to cut off Farmer’s escape routes and targeted the body with punishing shots.
The blows came in bunches.
In the fifth round Zepeda blasted away at Farmer who looked frantic for an escape. The body assault continued with the Mexican fighter pouring it on and Farmer seeming to look ready to quit. When the round ended, he waved off his corner’s appeals to stop.
Zepeda continued to dominate the next few rounds and then Farmer began rallying. At first, he cleverly smothered Zepeda’s body attacks and then began moving and hitting sporadically. It forced the Mexican fighter to pause and figure out the strategy.
Farmer, a Philadelphia fighter, showed resiliency especially when it was revealed he had suffered a hand injury.
During the last three rounds Farmer dug down deep and found ways to score and not get hit. It was Boxing 101 and the Philly fighter made it work.
But too many rounds had been put in the bank by Zepeda. Despite the late rally by Farmer one judge saw it 114-114, but two others scored it 116-112 and 115-113 for Zepeda who retains his interim lightweight title and place at the top of the WBC rankings.
“I knew he was a difficult fighter. This time he was even more difficult,” said Zepeda.
Farmer was downtrodden about another loss but realistic about the outcome and starting slow.
“But I dominated the last rounds,” said Farmer.
Zepeda shrugged at the similar outcome as their first encounter.
“I’m glad we both put on a great show,” said Zepeda.
Female Flyweight Battle
Costa Rica’s Yokasta Valle edged past Texas fighter Marlen Esparza to win their showdown at flyweight by split decision after 10 rounds.
Valle moved up two weight divisions to meet Esparza who was slightly above the weight limit. Both showed off their contrasting styles and world class talent.
Esparza, a former unified flyweight world titlist, stayed in the pocket and was largely successful with well-placed jabs and left hooks. She repeatedly caught Valle in-between her flurries.
The current minimumweight world titlist changed tactics and found more success in the second half of the fight. She forced Esparza to make the first moves and that forced changes that benefited her style.
Neither fighter could take over the fight.
After 10 rounds one judge saw Esparza the winner 96-94, but two others saw Valle the winner 97-93 twice.
Will Valle move up and challenge the current undisputed flyweight world champion Gabriela Fundora? That’s the question.
Valle currently holds the WBC minimumweight world title.
Puerto Rico vs Mexico
Oscar Collazo (12-0, 9 KOs), the WBO, WBA minimumweight titlist, knocked out Mexico’s Edwin Cano (13-3-1, 4 KOs) with a flurry of body shots at 1:12 of the fifth round.
Collazo dominated with a relentless body attack the Mexican fighter could not defend. It was the Puerto Rican fighter’s fifth consecutive title defense.

Avila Perspective, Chap. 319: Rematches in Las Vegas, Cancun and More

Rematches are the bedrock for prizefighting.
Return battles between rival boxers always means their first encounter was riveting and successful at the box office.
Six months after their first brutal battle Mikaela Mayer (20-2, 5 KOs) and Sandy Ryan (7-2-1, 3 KOs) will slug it out again for the WBO welterweight world title this time on Saturday, March 29, at the Fontainebleau in Las Vegas.
ESPN will show the Top Rank card live.
“It’s important for women’s boxing to have these rivalries and this is definitely up there as one of the top ones,” Mayer told the BBC.
If you follow Mayer’s career you know that somehow drama follows. Whether its back-and-forth beefs with fellow American fighters or controversial judging due to nationalism in countries abroad. The Southern California native who now trains in Las Vegas knows how to create the drama.
For female fighters self-promotion is a necessity.
Most boxing promoters refuse to step out of the usual process set for male boxers, not for female boxers. Things remain the same and have been for the last 70 years. Social media has brought changes but that has made promoters do even less.
No longer are there press conferences, instead announcements are made on social media to be drowned among the billions of other posts. It is not killing but diluting interest in the sport.
Women innately present a different advantage that few if any promoters are recognizing. So far in the past 25 years I have only seen two or three promoters actually ignite interest in female fighters. They saw the advantages and properly boosted interest in the women.
The fight breakdown
Mayer has won world titles in the super featherweight and now the welterweight division. Those are two vastly different weight classes and prove her fighting abilities are based on skill not power or size.
Coaching Mayer since amateurs remains Al Mitchell and now Kofi Jantuah who replaced Kay Koroma the current trainer for Sandy Ryan.
That was the reason drama ignited during their first battle. Then came someone tossing paint at Ryan the day of their first fight.
More drama.
During their first fight both battled to control the initiative with Mayer out-punching the British fighter by a slender margin. It was a back-and-forth struggle with each absorbing blows and retaliating immediately.
New York City got its money’s worth.
Ryan had risen to the elite level rapidly since losing to Erica Farias three years ago. Though she was physically bigger and younger, she was out-maneuvered and defeated by the wily veteran from Argentina. In the rematch, however, Ryan made adjustments and won convincingly.
Can she make adjustments from her defeat to Mayer?
“I wanted the rematch straight away,” said Ryan on social media. “I’ve come to America again.”
Both fighters have size and reach. In their first clash it was evident that conditioning was not a concern as blows were fired nonstop in bunches. Mayer had the number of punches landed advantage and it unfolded with the judges giving her a majority decision win.
That was six months ago. Can she repeat the outcome?
Mayer has always had boiler-oven intensity. It’s not fake. Since her amateur days the slender Southern California blonde changes disposition all the way to red when lacing up the gloves. It’s something that can’t be taught.
Can she draw enough of that fire out again?
“I didn’t have to give her this rematch. I could have just sat it out, waited for Lauren Price to unify and fought for undisputed or faced someone else,” said Mayer to BBC. “That’s not the fighter I am though.”
Co-Main in Las Vegas
The co-main event pits Brian Norman Jr. (26-0, 20 KOs) facing Puerto Rico’s Derrieck Cuevas (27-1-1, 19 KOs) in a contest for the WBO welterweight title.
Norman, 24, was last seen a year ago dissecting a very good welterweight in Giovani Santillan for a knockout win in San Diego. He showed speed, skill and power in defeating Santillan in his hometown.
Cuevas has beaten some solid veteran talent but this will be his big test against Norman and his first attempt at winning a world title.
Also on the Top Rank card will be Bruce “Shu Shu” Carrington and Emiliano Vargas, the son of Fernando Vargas, in separate bouts.
Golden Boy in Cancun
A rematch between undefeated William “Camaron” Zepeda (32-0, 27 KOs) and ex-champ Tevin Farmer (33-7-1, 8 KOs) headlines the lightweight match on Saturday March 29, at Cancun, Mexico.
In their first encounter Zepeda was knocked down in the fourth round but rallied to win a split-decision over Farmer. It showed the flaws in Zepeda’s tornado style.
DAZN will stream the Golden Boy Promotions card that also includes a clash between Yokasta Valle the WBC minimumweight world titlist who is moving up to flyweight to face former flyweight champion Marlen Esparza.
Both Valle and Esparza have fast hands.
Valle is excellent darting in and out while Esparza has learned how to fight inside. It’s a toss-up fight.
