Every Supplement That Builds Muscle Faster Than Protein

what it claims

For building muscle, only two supplements have solid, consistent evidence — creatine monohydrate (3-5g/day) and protein powder if your food intake is already falling short. Everything else — turkesterone, HMB, testosterone boosters, mass gainers — is either ineffective or only situational, and the placebo effect (believing it works) sometimes outweighs the compound itself.

Source cited in the video: a Doctor of Sports Nutrition consulted by the creator, plus named studies (a 2023 analysis on turkesterone underdosing, a 1972 trial on the placebo effect). Evidence type: a narrative review built on controlled trials. The grounding confirms the ranking: three separate randomized trials published in 2024-2025 (MDPI; Research in Health and Medicine; Journal of the International Society of Sports Nutrition) found no effect of turkesterone on IGF-1, body composition, or strength in humans, at doses up to 2000mg/day — the video is in step with an already clearly negative literature here. Creatine (3-5g/day monohydrate) remains the best-established supplement for strength and lean mass in resistance-trained people. Protein powder only adds real gains when total intake sits below target (~0.7-1g/lb); above that, it mostly adds convenience. Over-the-counter testosterone boosters only nudge testosterone within the normal range, except when correcting a genuine zinc, magnesium, or boron shortfall. Direction: likely causal for creatine and protein (controlled trials), null for turkesterone and boosters.
