Most men looking at peptides want help with recovery, sleep, body composition or training load. Here is the straight version: the peptides listed here are compounded, not FDA-approved, and prescribed only after a clinical evaluation. The strength of evidence differs a lot from one peptide to the next, and several are banned in tested sport. We do not source or recommend research-only products sold for human use.
Sermorelin
InjectionA lab-made version of the hormone that signals the pituitary to release growth hormone (a GHRH analogue). Men usually ask about it for sleep, recovery and body composition. Those benefits are possible, not proven, and the evidence trails well behind FDA-approved growth hormone treatments. It is on the WADA prohibited list, which matters if you compete in tested sport.
- Compounded at a licensed 503A/503B compounding pharmacy.
- Requires a valid prescription.
Ask about this treatmentGlutathione
InjectionYour body makes glutathione, a key antioxidant, on its own. Injected glutathione is marketed for oxidative stress and cell health, and some men pair it with hard training or recovery goals. Studies of injections in healthy people are inconsistent, so treat any benefit as uncertain rather than expected.
- Compounded at a licensed 503A/503B compounding pharmacy.
- Requires a valid prescription.
Ask about this treatmentBPC-157
InjectionA synthetic peptide modeled on a fragment of a protein found in stomach fluid. It draws interest from lifters and athletes for tendon, ligament and gut recovery, but nearly all of the evidence comes from animal studies. Human trials are scarce, so it remains a research-stage compound, and WADA bans it for tested athletes.
- Compounded at a licensed 503A/503B compounding pharmacy.
- Limited human data.
Ask about this treatmentGHK-Cu
InjectionA copper-binding peptide researched mainly for skin repair and wound healing, with antioxidant and tissue-remodeling effects seen in lab work. Injecting it for whole-body wellness or recovery is far less supported than applying it to skin. Men curious about it should know the systemic case is the weaker one.
- Compounded at a licensed 503A/503B compounding pharmacy.
- Requires a valid prescription.
Ask about this treatmentGHK-Cu Topical Cream
Topical creamThe copper peptide GHK-Cu in a compounded cream applied directly to skin. Men usually ask about it for skin texture and firmness, and it has been studied for wound healing. The research behind topical use is stronger than for injections, but individual results vary and the compounded cream is not an FDA-approved product.
- Compounded at a licensed 503A/503B compounding pharmacy.
- Requires a valid prescription.
Ask about this treatmentMOTS-C
InjectionA peptide encoded in mitochondrial DNA, studied for how it may influence metabolism, insulin sensitivity and exercise capacity. That makes it interesting to men focused on conditioning and metabolic health. Most findings come from animal and early human work, so real-world benefit is unknown.
- Compounded at a licensed 503A/503B compounding pharmacy.
- Early-stage human data.
Ask about this treatmentTesamorelin
InjectionA GHRH analogue whose FDA-approved use is reducing excess abdominal fat in people with HIV-associated lipodystrophy. Because that indication targets belly fat, men sometimes ask about it for visceral fat. Compounded tesamorelin used for general body composition or anti-aging is not FDA-approved for those purposes, and it is prohibited in tested sport.
- Compounded at a licensed 503A/503B compounding pharmacy.
- Not FDA-approved for general use.
Ask about this treatmentEpithalon
InjectionA four-amino-acid synthetic peptide studied for possible effects on telomeres and aging. It shows up often in longevity circles, but almost all of the data come from animal and cell studies, and human evidence is very thin. For men focused on healthy aging, proven basics like labs, training and sleep still come first.
- Compounded at a licensed 503A/503B compounding pharmacy.
- Very limited human data.
Ask about this treatmentSS-31
InjectionSS-31 (elamipretide) is a peptide that targets mitochondria. An elamipretide product received FDA accelerated approval in 2025 only for Barth syndrome, a rare inherited disease; compounded SS-31 is not that product. Men ask about it for heart health, endurance and aging, but human data for those uses are limited and early-stage.
- Compounded at a licensed 503A/503B compounding pharmacy.
- Early-stage human data.
Ask about this treatmentThymosin Alpha-1
InjectionA peptide first isolated from the thymus and researched for its effects on immune function. Some countries have used it for hepatitis and immune support, but it is not FDA-approved in the US, and evidence for everyday wellness or immune resilience during heavy training in healthy men is limited.
- Compounded at a licensed 503A/503B compounding pharmacy.
- Not FDA-approved in the US.
Ask about this treatmentSemax + Selank Stack
InjectionTwo neuropeptides developed in Russia and studied there for focus and anxiety-related effects. Men drawn to them usually want sharper concentration or a calmer stress response. Rigorous Western peer-reviewed human trials are very limited, so any cognitive benefit should be considered unproven.
- Not FDA-approved.
- Compounded product.
- Very limited Western clinical data.
Ask about this treatmentCJC-1295 + Ipamorelin Stack
InjectionPairs CJC-1295, a GHRH analogue, with ipamorelin, a growth hormone secretagogue, to prompt the body's own growth hormone release. It is popular with men interested in sleep, recovery and lean mass, but the evidence is thinner than for approved growth hormone therapies. Both are prohibited under WADA rules, and the stack does not replace TRT or lab-guided care.
- Compounded at a licensed 503A/503B compounding pharmacy.
- Requires a valid prescription.
Ask about this treatmentWolverine Stack: BPC-157 + TB-500
InjectionBPC-157 combined with TB-500, a fragment related to thymosin beta-4. Both have been studied for tissue repair and recovery in animals, which is why the stack is popular with men managing training injuries. Human data are limited for each peptide, no clinical trial has tested the pair together, and both are banned in tested sport.
- Compounded at a licensed 503A/503B compounding pharmacy.
- Limited human data.
Ask about this treatmentGlow Stack: BPC-157 + TB-500 + GHK-Cu
InjectionThree peptides in one: BPC-157, TB-500 and GHK-Cu, aimed at tissue repair, recovery and skin. Men who train hard sometimes ask about it for recovery and skin quality at once. Each ingredient has limited human data, and no clinical trial has studied the three together, so the combination's effects are unknown.
- Compounded at a licensed 503A/503B compounding pharmacy.
- Limited human data.
Ask about this treatmentKlow Stack: BPC-157 + TB-500 + GHK-Cu + KPV
InjectionThe Glow Stack plus KPV, a small melanocortin-derived peptide researched for anti-inflammatory activity. It comes up with men who want a broader recovery blend. No clinical trial data exist for this four-peptide combination, and adding ingredients does not add proof. Ask what each component is meant to do before considering it.
- Compounded at a licensed 503A/503B compounding pharmacy.
- No combination clinical data.
Ask about this treatmentPT-141
InjectionBremelanotide, a melanocortin receptor agonist studied in sexual dysfunction. The FDA-approved bremelanotide product is approved only for low sexual desire in premenopausal women, so use in men is off-label, and compounded versions are not FDA-approved. It does not replace an erectile dysfunction workup, since ED can be an early sign of heart or hormone problems.
- Compounded at a licensed 503A/503B compounding pharmacy.
- Off-label use in men.
