No, creatine does not meaningfully raise or lower your testosterone. Its real benefit is training performance, not hormones, and the evidence on that is unusually clear.
Across more than a dozen trials using 3 to 25 g a day for up to 12 weeks, the consistent finding is no change in total or free testosterone. The most thorough review, published in the Journal of the International Society of Sports Nutrition, concluded that creatine does not increase total testosterone, free testosterone or DHT. So the popular idea that creatine is a testosterone booster simply is not supported.
Two myths are worth clearing up directly:
So why do people feel more anabolic on it? Because creatine lets you train harder, with more reps, more power and more lean mass over time, and that improvement is what indirectly supports healthy hormones. Creatine works through your muscles' energy system, not your testes, which is the same reason the strength it adds does not show up as a hormone change but as better sessions. It is also one of the most-researched and safest supplements available, more than can be said for most of the booster aisle, and the muscle it helps you build is genuinely useful given how little the post-workout hormone spike matters (see does testosterone build muscle).
What to do: if you lift, creatine monohydrate at around 3 to 5 g a day is a cheap, well-evidenced way to train harder and recover better, but do not expect it to move your testosterone. For that, focus on the basics in raising testosterone naturally: sleep, body fat and training.
