The community is questioning the true nature of the mass gains associated with creatine, suspecting that they primarily result from intracellular water retention rather than genuine muscle growth, and is wondering whether these benefits disappear once supplementation is stopped.

Science confirms that creatine promotes an increase in lean mass, but this increase is multifactorial. Meta-analyses (notably Kreider et al., Journal of the International Society of Sports Nutrition) demonstrate that while initial water retention occurs, it is accompanied by a real improvement in training performance, allowing for a greater volume of work that promotes protein synthesis over the long term. The idea that gains are 'purely' water is therefore an exaggeration, although this volumizing effect is real and rapid. Regarding cessation, studies show that muscle creatine levels gradually return to baseline over a few weeks, which leads to a loss of this water surplus, but not necessarily of the muscle mass built through intense effort. The community is currently in a phase of rational skepticism, seeking to distinguish the immediate aesthetic aspect from the lasting metabolic effect. The evidence for overall efficacy is robust (meta-analyses), but the nuance between 'swelling' and 'growth' remains a frequent point of confusion. The consensus on the thread is moderate, with users qualifying the scope of the scientific results presented.
