Natural anabolic evidence brief

Deer antler velvet

Human evidence does not support common IGF-1, testosterone, aerobic, or broad strength-performance claims.

Anabolic claims unsupported strength / hypertrophy / recovery 5 linked sources Content audit 2026-05-04

Headline Finding

38-man RCT: no endocrine, red-cell, or VO2max benefit; strength signal was inconsistent.

Dose Context

Powder, extract, and spray products vary widely, so small trials do not generalize well.

Important Caveat

Product identity, anti-doping concern, and weak human evidence make this a poor trust-led recommendation.

How To Read This Rating

The score reflects evidence that the supplement does its stated job. Some jobs are direct, such as strength, endurance, or recovery; others are indirect, such as sleep, mood, appetite, or health support. A real effect can still receive a cautious practical rating when dose, safety, product quality, or audience fit remain uncertain.
