Peptides & Anti-Doping in South Africa

If you compete in a sport that is covered by anti-doping rules, this is the article to read before any other on this site.

Recovery peptides are discussed in gyms and change rooms as if they were supplements. Under the anti-doping rules they are nothing of the sort. Most of the peptides athletes ask us about are on the World Anti-Doping Agency's Prohibited List, the majority are banned at all times rather than only on match day, and the rules do not care whether you knew.

This guide sets out what the 2026 list actually says, how the rules are enforced in South Africa, and why "I only used it for an injury" is not a defence.

Who the Rules Apply To

The South African Institute for Drug-Free Sport (SAIDS) is the national anti-doping organisation, established by the SA Institute for Drug-Free Sport Act of 1997. It applies the World Anti-Doping Code and WADA's Prohibited List in South Africa.

The rules follow the sport, not the level. If your federation has adopted anti-doping rules, you can be tested. That includes national and provincial athletes, and it includes schoolboy rugby. Positive tests at the U18 Craven Week have been reported almost every year: four in 2011, three in 2014, five in 2015, four in 2016, three in 2017, six in 2018, five in 2022 and three in 2023, almost all involving anabolic steroids.

Most recreational gym-goers will never be tested. But "recreational" ends the day you enter a sanctioned competition, and the rules apply to what was in your system then, not to when you decided to compete.

What the 2026 Prohibited List Says About Peptides

The list in force from 1 January 2026 covers the peptides we are most often asked about in three places.

S0, Non-Approved Substances. Any pharmacologically active substance that is not covered elsewhere on the list and has no current approval from any government health authority for human therapeutic use. The list names BPC-157 as an example. S0 is prohibited at all times, in and out of competition.

S2, Peptide Hormones, Growth Factors, Related Substances and Mimetics. Prohibited at all times. It includes:

• Growth hormone releasing factors: GHRH analogues including CJC-1295, sermorelin and tesamorelin; growth hormone secretagogues including ipamorelin and ibutamoren (MK-677); and the GH-releasing peptides, including GHRP-2, GHRP-6 and hexarelin.
• Growth hormone fragments, including AOD-9604 and hGH 176-191.
• Growth factors, including IGF-1 and its analogues such as IGF-1 LR3, mechano growth factors, and thymosin beta-4 and its derivatives, such as TB-500.
• Testosterone-stimulating peptides in males, including chorionic gonadotrophin (hCG), gonadorelin and kisspeptin and its analogues.

S4.4, Metabolic Modulators. Prohibited at all times. It names AMPK activators, and lists MOTS-c by name.

So the Wolverine stack, the growth hormone secretagogue stacks and MOTS-c are all prohibited for tested athletes at all times, not just in competition.

What About the GLP-1 Compounds?

Semaglutide and tirzepatide are not named on the 2026 list, and because they are approved medicines they do not fall under S0.

Compounds still in clinical development are a different matter. S0 explicitly covers "drugs under pre-clinical or clinical development". As of mid-2026, SAHPRA described retatrutide as still under clinical investigation and not approved in any market, which puts it within the plain wording of S0. The same reasoning applies to any peptide that has not been approved as a medicine anywhere in the world.

If a compound is not on the list by name, that is not the same as it being permitted. Check before you use it, not after.

Strict Liability, and Why Intent Does Not Matter

The Code works on strict liability. In SAIDS's words, you are "ultimately responsible for everything that goes into your body." An anti-doping rule violation is established by the presence of a prohibited substance in your sample. Intent, fault and knowledge do not have to be proven.

Two consequences follow that athletes often miss:

• A positive test is not the only route to a ban. Use or attempted use, and possession of a substance prohibited at all times, are violations in their own right, and can be proven with evidence such as admissions or purchase records.
• Contamination is your problem. SAIDS points out that supplement manufacturing is not regulated in South Africa, and that buying from a reputable retailer will not absolve you. An international study of 634 non-hormonal supplements found that 14.8% contained anabolic steroids that were not on the label. Research peptides, sold outside any medicines regulation, carry at least the same risk of containing something other than what the label says.

How Long a Ban Lasts

Under the World Anti-Doping Code, a first violation involving a non-specified substance carries a four-year ban, reduced to two years only if the athlete can prove it was not intentional. Everything in S2 and S4.4 is non-specified, so this is the starting point for TB-500, the growth hormone secretagogues and MOTS-c.

S0 substances such as BPC-157 are classed as specified. The starting point there is two years, rising to four if the anti-doping organisation shows the use was intentional.

Reductions for no significant fault exist, but they are narrow and the burden of proof sits with the athlete.

Can These Peptides Actually Be Detected?

Yes. Anti-doping laboratories have published validated methods for many of them:

• The Cologne laboratory has published a urine method covering GHRH analogues including CJC-1295, sermorelin and tesamorelin, along with IGF-1 analogues, gonadorelin and mechano growth factors, designed for routine doping control.
• The Ghent laboratory identified the thymosin beta-4 fragment in TB-500 products and proposed a detection strategy in plasma and urine as early as 2012.
• The Shanghai anti-doping laboratory published a method in 2023 for detecting BPC-157 and five of its metabolites in human urine.

Assuming a compound is invisible to testing because it is new or unusual is a poor bet, and, as above, the rules do not require a positive test.

What About Genuine Injuries?

If you have a medical condition that genuinely needs a prohibited substance, the route is a Therapeutic Use Exemption (TUE). SAIDS requires national-level athletes to apply in advance. All four criteria have to be met, including that there is no reasonable permitted alternative.

In practice a TUE is granted for an indicated treatment of a diagnosed condition. BPC-157 is not an approved medicine anywhere, so it has no indication to be granted for. Recovery peptides are not a TUE pathway.

What is permitted, and what the evidence behind injury recovery mostly rests on, is proper rehabilitation, load management, sleep and nutrition. Our recovery protocol guide covers the foundations, and those apply to tested and untested athletes alike.

Before You Take Anything

• Check every medication on the SAIDS Medication Check tool at drugfreesport.org.za, and tell your doctor you are subject to testing.
• Treat every supplement as a risk. SAIDS says it cannot guarantee or advise which supplements are free from contamination.
• Do not take a compound because a teammate or coach says it is "not tested for". Coaches and support staff are also bound by the rules.
• If you are a parent of a schoolboy athlete, the same rules apply to your child at Craven Week and similar events.

The Bottom Line

For a tested athlete, BPC-157, TB-500, the growth hormone secretagogues, IGF-1 LR3 and MOTS-c are prohibited at all times, and anything without regulatory approval anywhere sits under S0. Strict liability means how it got into your system is not a defence.

We would rather lose a sale than have an athlete lose a career. If you compete under anti-doping rules, the peptides discussed on this site are not for you. Our broader guide for South African athletes covers the evidence, but the anti-doping answer comes first.
