Supplements for Athletic Performance

Complete protein with high leucine content that maximizes muscle protein synthesis — most researched protein supplement worldwide.

Leucine metabolite with small benefits to muscle mass in clinical and older populations, but meta-analyses show no effect on body composition or strength in trained, healthy adults.

Leucine, isoleucine, and valine metabolized directly in muscle tissue — support protein synthesis and reduce exercise fatigue.

Proven ergogenic aid that buffers lactic acid, extending high-intensity exercise capacity by 1-3%.

Hydrolyzed peptides that rebuild skin elasticity, reduce joint pain, and strengthen bone density — results build over 8-12 weeks.

An injectable anabolic-androgenic steroid (AAS) — brand Deca-Durabolin, the long-acting decanoate ester of 19-nortestosterone — and a DEA Schedule III CONTROLLED SUBSTANCE. It has genuine randomized-trial evidence in supervised, catabolic-illness settings: it adds lean body mass and weight in HIV-associated wasting, adds muscle mass and physical function in dialysis patients, and raises hemoglobin in dialysis anemia (a historic FDA-approved indication, since largely replaced by erythropoietin). But it suppresses the hypothalamic-pituitary-gonadal axis — and because it is a long-ester 19-nortestosterone with progestogenic activity, that suppression and the resulting sexual dysfunction ('deca dick') can be prolonged. It worsens the lipid profile (lowers HDL), is associated with cardiac remodelling/cardiomyopathy and premature atherosclerosis in long-term high-dose users, and virilizes. It is NOT a dietary supplement and NOT a longevity drug; non-medical bodybuilding/performance use is illegal without a prescription and carries real cardiovascular, endocrine and sexual harm. Informational, harm-reduction entry only — not a recommendation.

Dietary nitrates convert to nitric oxide, enhancing oxygen delivery to muscles — a top-5 evidence-based ergogenic aid.

Blocks adenosine receptors to boost alertness, reaction time, and endurance — one of the most proven ergogenic aids.

A traditional fungus marketed for energy and endurance. The honest verdict: those claims rest on small, often-mixed trials — several found no benefit — while the stronger evidence covers adjuvant kidney and COPD use instead.

Proteolytic enzyme from pineapple that aids digestion with food or provides systemic anti-inflammatory and recovery benefits on an empty stomach.

Rate-limiting precursor to glutathione, the body's master antioxidant — supports mood, respiratory health, and liver protection.

A Traditional Chinese Medicine herb. The honest verdict: many meta-analyses suggest adjuvant benefit for diabetic kidney disease and immune markers, but they rest on low-quality Chinese trials of combination formulas, and the headline longevity/telomere claims are thin or animal-only.
