Ranked by data
The best SARMs for bulking and lean mass, ranked by muscle-growth effectiveness scores — dosing, PCT requirements, and where research labs source them.
10 compounds · ranked by muscle growth score
Every SARM and research anabolic in our library carries a 0–10 muscle-growth effectiveness score, kept current by our content pipeline. This ranking sorts the full SARM class by that score — no pay-to-play, no vibes. Each entry links to the full compound guide covering dosing tiers, cycle length, suppression, and PCT requirements.

Every compound in our library is scored 0–10 on six effectiveness axes (muscle growth, fat loss, strength, endurance, recovery, cognition) as part of our content pipeline. This page filters the library to SARM and sorts by the muscle growth score. Compounds that score zero on this axis are omitted. Rankings recompute automatically whenever the underlying compound data changes — they are never influenced by affiliate relationships.
