About this episode

This episode discusses a 90-day study on creatine involving 12 participants, exploring its effects on strength, body composition, recovery, and focus.

Creatine is one of the most researched supplements on earth — and also one of the most hyped, doubted, and misunderstood. So instead of arguing about it, REP Fitness ran the experiment: they took 12 people who had never touched creatine, held their training steady, and tracked everything for 90 days. This episode unpacks exactly what happened. Jesse sits down with Ashley Boyer — Editor-in-Chief at REP Fitness, certified personal trainer, and the sports-performance researcher who designed and ran the study — to walk through the whole thing: how she built it, what she measured, and what the data actually showed on strength, body composition, recovery, and focus. You'll hear the standout results, the honest caveats and side effects, and the practical takeaways for anyone deciding whether creatine is worth it. No hype, no sales pitch — just the numbers and what they mean for you. If you've ever wondered whether creatine actually lives up to the claims, this is the honest, evidence-based answer.
