Best compounds
for muscle

Creatine, Cr

The single most evidence-backed ergogenic supplement in existence. Increases phosphocreatine stores, allowing more ATP to be rapidly regenerated during high-intensity work. The result is more reps, more sets, faster recovery between efforts, and — over time — meaningfully more lean mass. If you are not on creatine, start before anything else on this page.

Citrulline Malate

Converts to arginine and then nitric oxide, increasing blood flow to working muscle. Reduces ammonia accumulation during training, which is a primary driver of early fatigue. The practical result is more reps per set before failure, which compounds over weeks and months of training into meaningfully more volume-driven growth.

MK-2866, Enobosarm

The most studied SARM in human trials. Selectively activates androgen receptors in muscle and bone without the systemic androgenic effects of testosterone. Suppression is real but mild at lower doses — most users recover naturally within 4–6 weeks. Its value is as a diagnostic: it shows you how your body handles an androgen receptor modulator and what mild suppression actually feels like before you encounter the real thing.

Ligandrol

The most potent SARM for raw lean mass accrual. Produces gains in the range of a mild steroid cycle, with a slightly cleaner risk profile. Suppression is significant — expect testosterone to drop meaningfully during the cycle. Lipid panels typically worsen. PCT is not optional. The gains are real; so is the recovery requirement.

Testolone

Closer to testosterone in androgenic potency than any other SARM, but with greater receptor selectivity. Produces a drier, harder look than LGD-4033 with less water retention. Strength increases are often more pronounced than the scale suggests. Suppression profile is comparable to LGD. Some users report androgenic side effects like aggression at higher doses. PCT is mandatory.

Ibutamoren

Orally active ghrelin receptor agonist that stimulates GH release from the pituitary. Unlike injectable GH, it works through the natural pulsatile release pattern, which is safer and cheaper. Primary benefits are improved sleep quality, faster tissue repair, and IGF-1 elevation. Direct muscle-building effect is modest as a standalone, but strong as a stack addition. Insulin sensitivity impairment over time is a real monitoring concern.

Long R3 Insulin-like Growth Factor-1

A modified form of IGF-1 with an extended half-life. Drives muscle cell proliferation and may stimulate genuine hyperplasia — new muscle fiber creation, not just hypertrophy of existing fibers. The evidence base in humans is limited. The hypoglycemia risk is not theoretical: it has sent people to the ER. This belongs in experienced hands only, run alongside a complete protocol, not as a standalone experiment.

Test, Test E / Test C / Test P

The molecule against which every other anabolic compound is measured. Exogenous testosterone is simultaneously the most studied, most effective, and most consequential compound on this page. A first cycle at 300–500 mg/week with proper training and nutrition produces results that no other intervention — legal or otherwise — can match. HPTA shutdown is complete during the cycle. Estrogen control via an AI is typically required. PCT is mandatory. Long-term use at any dose suppresses natural production indefinitely.
