The Legal Landscape of Performance Enhancers in Sports

Same drugs, different rulebooks

Lifters tend to lump anabolic steroids and SARMs together with peptides as one family of performance enhancers. Sports bodies don't. Each anti-doping program sorts these drugs by how they act, then attaches its own penalties. A positive test for the same SARM can cost an Olympic athlete four years and an NFL player six games.

This page compares how the main rulebooks treat the three groups as of October 2026: the World Anti-Doping Agency (WADA) Code, which USADA enforces in US Olympic sport; the NCAA's rules for college athletes; and the drug policies of the NFL and MLB, plus the UFC. It's part of our steroids and SARMs comparison hub and covers sport rules only. Our US legal overview for these compounds covers the law, and peptides and anti-doping testing explains how WADA testing works in practice.

How WADA files each group

WADA's 2026 Prohibited List has been in force since January 1, 2026. The 2027 List takes effect on January 1, 2027. Both ban all three groups at all times (in and out of competition), but they file them in different sections.

• Anabolic steroids sit in S1.1. Testosterone and nandrolone are there, along with dozens of designer steroids and prohormones.
• SARMs sit in S1.2, "other anabolic agents." The named examples include enobosarm (ostarine) and LGD-4033 and run through to YK-11. The section says "including, but not limited to," so an unnamed SARM is still covered.
• Peptides are spread across four sections. Growth hormone releasing compounds (CJC-1295, sermorelin, ipamorelin, the GHRPs) are in S2.2.4, and ibutamoren (MK-677), which isn't a peptide at all, sits beside them. TB-500 is in S2.3 as a thymosin-β4 derivative, next to IGF-1 analogues such as IGF-1 LR3. BPC-157 is named under S0, the class for substances with no government approval for human use. MOTS-c is named in S4.4 as a metabolic modulator.

Not every peptide is banned. Semaglutide and tirzepatide aren't prohibited; they stay in WADA's Monitoring Program for 2027, which means labs track them without any sanction attached. Bremelanotide (PT-141, sold as Vyleesi) and elamipretide (SS-31, now sold as Forzinity) are FDA-approved prescription medicines. S0's "no current approval" test no longer fits them, and as of October 2026 we couldn't confirm whether another section covers them.

Where the groups split: specified or non-specified

Under the World Anti-Doping Code, the default ban for a first violation depends on whether a substance is "specified." That label isn't a danger rating. WADA's list describes specified substances as ones "more likely to have been consumed or used by an Athlete for a purpose other than the enhancement of sport performance."

The 2026 list makes everything in S1 and S2 non-specified, along with S4.4, while everything in S0 is specified. That splits the peptide group.

So an athlete caught with a SARM or a GH secretagogue has to prove the violation wasn't intentional to get two years. With BPC-157 the burden flips: the agency has to prove intent to reach four. Fault-based reductions can apply either way, so these are starting points.

Repeat offenses climb steeply. In a 2024 USADA arbitration, a sprinter who had already served 16 months for ostarine tested positive for three SARMs (LGD-4033 and RAD-140 among them) plus the metabolic modulator SR9009. He got eight years.

What changes in 2027

USADA's athlete advisory on the 2027 list says the S0 description now names "peptides" as an example of a non-approved substance, next to designer drugs and veterinary-only products. USADA also warns that "the current 'peptide craze' may pose serious anti-doping and health risks," and that not every prohibited peptide appears in its Global DRO lookup tool. We've taken this from USADA's summary and haven't yet checked the wording against WADA's own 2027 PDF.

The NCAA: one penalty for every class

The NCAA's 2026-27 list bans drug classes rather than individual compounds, and it states plainly that "there is no complete list of banned substances." Its anabolic agents class names steroids such as testosterone and trenbolone, plus four SARMs; LGD-4033 and ostarine are two of them. Its peptide hormones class names BPC-157 and TB-500 alongside hGH and IGF-1, and it files ibutamoren (MK-677) there too. CJC-1295 and ipamorelin aren't named, but the NCAA bans anything "chemically/pharmacologically related" to a listed class.

The penalty doesn't depend on which class a drug sits in. Under the 2026-27 Division I consent form, a first positive for any banned drug other than a narcotic means 365 consecutive days of ineligibility and the loss of a season of competition in all sports. A second positive costs all remaining eligibility. A missed test counts the same as a positive. Unlike WADA, then, the NCAA treats a BPC-157 positive exactly like a trenbolone positive.

The NCAA also warns that student-athletes "have tested positive and lost their eligibility using nutritional/dietary supplements." That matters most for SARMs, which FDA says are generally marketed as dietary supplements even though they're unapproved drugs.

Pro leagues and the UFC

US pro leagues aren't bound by the WADA Code. They negotiate drug policies with players' unions, and the two league policies we checked group all three classes together.

NFL. The 2026 Policy on Performance-Enhancing Substances puts steroids under one heading, "Anabolic Agents," together with SARMs and a "protein and peptide hormones" section that names BPC-157. A first positive for any anabolic agent brings a six-game unpaid suspension. A second brings 17 games, and a third means banishment for at least two seasons. The prohibited list printed in the policy, last updated in August 2022, names BPC-157 but not TB-500.

MLB. The Joint Drug Program (the 2022 version posted by the players' union) lists SARMs as performance-enhancing substances. A separate entry covers "Human Growth Hormone (hGH), Secretagogues and Peptides," naming CJC-1295 and ipamorelin as well as TB-500. A first violation brings an 80-game suspension; a second brings 162 games; a third is a permanent ban. An arbitration panel can cut a first-offense ban to as low as 30 games for a player with no significant fault, but not for testosterone or a few named steroids, and not for anything in the GH and peptides entry. In MLB, then, a peptide positive gets less room for mitigation than most steroid positives.

UFC. Since December 31, 2023, the UFC's program has been run independently by Combat Sports Anti-Doping (CSAD), with samples analyzed at a WADA-accredited lab in Salt Lake City. Its prohibited list is modeled on WADA's, with changes such as dropping marijuana. CSAD can reduce bans for cooperation. In May 2026 it gave a fighter 12 months for an out-of-competition ipamorelin positive; he said a wellness clinic had supplied the product as an injury-recovery treatment he believed was permitted. CSAD found gross negligence but credited his help in identifying the clinic.

The event that allows them

The Enhanced Games, held in Las Vegas on May 24, 2026, were set up to permit substances the WADA Code bans. According to NBC News, 38 of the 42 athletes chose to use drugs. Testosterone and growth hormone were the most common. The chair of the event's medical commission said organizers started from "Take anything" and later limited athletes to FDA-approved drugs. By that account, unapproved compounds such as SARMs and BPC-157 were outside the program even at an event built around enhancement.

Two Olympic-sport federations have treated taking part as a problem in itself. World Aquatics adopted a bylaw barring people who participate in such events from its competitions and is judging athletes' eligibility case by case. World Athletics said it would assess even clean participants under its Integrity Code of Conduct.

Sport rules and the law are separate tracks

A sports ban doesn't depend on whether a drug is legal, and legality doesn't protect an athlete. The two systems often point in different directions.

• Steroids are Schedule III controlled substances under US federal law, and the Designer Anabolic Steroid Control Act of 2014 extended that status to structurally similar designer steroids.
• SARMs aren't federally scheduled as of October 2026. An earlier version of this page said the DEA had begun scheduling them; that was wrong. FDA treats SARM products as unapproved drugs rather than supplements. It also notes that some carry "for research purposes" labels while being sold for human use with dosing instructions.
• Peptides such as BPC-157 aren't controlled substances either. They're sold as research chemicals, a label we cover in what "research use only" means for peptides. Semaglutide shows the reverse case: it's a prescription medicine that WADA doesn't ban.

What to watch next

• Approved peptides. We couldn't find a WADA statement on how it treats bremelanotide or elamipretide now that both are approved drugs.
• GLP-1 drugs. Semaglutide and tirzepatide remain in the 2027 Monitoring Program, so any ban would have to come in a later list.
• Enhanced Games eligibility. World Aquatics' case-by-case rulings on athletes who competed in Las Vegas will show how far federations go in punishing participation itself.
