5-Hydroxytryptophan (Pot of 90 capsules)

Quality and purity are the Metabolics difference We want our nutritional supplements to do their job, and do it as effectively as possible. They need nothing to hold them back. So that's what we give them. It all starts with the ingredients. Quality out demands quality in. We source the best quality raw materials, of the highest purity, then we add ... next to nothing. Most of our capsules products contain only the active ingredients - and nothing else.
