For how we live.
The whole scare traces to one 2009 study that measured a hormone, not hair. In 2025, the first trial to actually assess hair follicles found no difference between creatine and placebo.
Creatine is not a testosterone booster — the trials show it leaves testosterone unchanged. The baldness scare traces to a single 20-man study that found a rise in DHT, a result no one has replicated in 15 years.
The training and creatine at its core rest on strong evidence. The supplement stack around them mostly doesn't — and the SARMs some users add are frequently not even the drug on the label.
A meta-analysis of 26 trials found creatine raises serum creatinine without markers of kidney injury. Weeks earlier, a Nature Communications paper reported that supplementation promoted metastasis in mice.
A meta-analysis of eleven depression trials found an average effect below the threshold for clinical importance, with signs of bias favouring creatine. A separate review found no change in kidney filtration.
A meta-analysis of 20 trials found a two-kilogram gain in one-rep max and no effect on bone density. A small crossover trial found functional strength gains largely independent of muscle mass.
