Why More Fighters Are Turning to SARMs and Peptides for Recovery and What the Science Actually Says

Recovery has become part of the fight for MMA fighters. A modern camp can mean morning striking, wrestling later in the day, strength work somewhere in between and then another round of conditioning before the week is over. The body gets very little time to forget what happened in the previous session. Naturally, fighters and their teams are looking for ways to make that recovery window work.

This helps explain why the buzz around recovery-focused compounds has gone beyond traditional gym culture, with companies such as BIAXOL operating in a wider space that has grown around peptide and performance research.

Early this year, as UFC 324 approached, the conversation reached the UFC spotlight when heavyweight Derrick Lewis spoke about injectable compounds he associated with peptides and the difference he felt in his recovery and conditioning. The UFC later clarified that the compounds were permitted, third-party-tested compounds rather than banned peptides.

And while Lewis’s comments came in January, the interest they reflected has continued to grow as fighters and sports researchers look for new approaches to recovery. It all raises a bigger question for MMA: what is the real extent of what science can do to help a fighter recover between grueling sessions?

Why Recovery Is Critical in MMA

A fighter doesn’t need to hurt himself badly to feel the effects of a hard camp. Constant striking, wrestling and grappling put plenty of strain on muscles, tendons and connective tissue. And then there’s conditioning. Strength work. Weight management. Travel. The list keeps getting longer, but the hours between sessions don’t change.

That makes recovery about more than comfort. If a fighter can’t recover properly, the quality of training can suffer too. And that’s where the interest in recovery compounds starts to make sense.

Why Fighters Are Interested in Peptides

“Peptides” sounds like one group, but it isn’t. They are short chains of amino acids, and they can interact with the body in very different ways. That’s why researchers are looking at them in areas including tissue repair, inflammation, metabolism and the growth-hormone pathway.

Names such as BPC-157, TB-500, CJC-1295 and ipamorelin have consequently become familiar in performance and recovery discussions.

The science is moving, too. A 2026 review in the American Journal of Sports Medicine examined several emerging peptides and their potential applications in sports medicine and musculoskeletal recovery. That doesn’t mean everything being said about these compounds is a fact. Not at all. Much of the research is still preclinical, and the amount of human evidence varies greatly from one compound to another.

Still, the growing research interest is hard to ignore. The conversation has moved well beyond whether peptides are simply another fitness fad.

What SARMs Have to Offer

SARMs come at the question from a different direction. Selective androgen receptor modulators are designed to interact with androgen receptors in a more tissue-selective way than conventional anabolic agents. The attraction for athletes is fairly obvious: keeping lean muscle and strength can be valuable when you’re training hard and also trying to make weight.

That doesn’t make SARMs interchangeable with peptides. The mechanisms are different, and so are the questions researchers are asking. There is also an important safety point here. SARMs are pharmacologically active compounds, not ordinary recovery supplements. Research has raised concerns about effects such as hormonal suppression, while the long-term safety of many SARMs in healthy athletes remains unclear. And for tested fighters, many SARMs are prohibited under anti-doping rules.

So the interest is real, but so are the reasons to approach the category carefully.

Even with that caveat, SARMs and peptides have entered the same larger conversation: how can athletes keep performing when their bodies are pushed again and again? For a fighter heading into five rounds, that’s hardly an abstract question.

What Science Actually Says

Here’s where some context is needed for all the excitement. Research on some peptides has produced promising findings, particularly in laboratory and animal models. But evidence from those settings can’t automatically be translated into quicker recovery after a hard MMA session. Many of the compounds that attract attention from athletes still have limited human research behind them.

That’s an important difference. A plausible biological mechanism is a reason to study a compound. It isn’t, by itself, proof that the compound will heal an injured tendon, eliminate soreness or get a fighter back on the mats faster. But limited evidence doesn’t mean the field is standing still.

Scientists are still looking at how different compounds interact with biological pathways and which potential applications can actually hold up when tested properly in humans. That’s where the next stage of the conversation will likely come from.

The Next Step in Fight Camp?

MMA has already changed dramatically in this regard. Nutrition is more sophisticated. Strength and conditioning has become an extremely specialized field. Fighters track sleep, training load and performance data in ways that would have seemed outlandish a generation ago.

Recovery is on the same track. One part of that evolution is the rising interest in peptides and SARMs. Fighters aren’t just interested in what they can do during a training session anymore. They’re increasingly interested in what helps them show up ready for the next one.

The science is still evolving, and the evidence varies greatly between compounds. But as fight camps become more data-driven and recovery becomes a bigger competitive concern, it’s easy to see why these compounds have entered the MMA conversation.
