One vial, three peptides, a fixed ratio. The appeal is arithmetic: one reconstitution, one injection, one thing to remember instead of three.

Skin renewal, tissue repair and connective-tissue signalling in a single mix. The ratio is set by the blend, which means you cannot push one component without pushing all of them. Eight weeks. If you want to know which part is working, this is the wrong protocol — that is the price of the convenience.
