Importantly, its not necessarily an either-or choice
This article takes a science-based look at both peptides, cutting through the hype to explore what the research actually says, who might benefit, and where the risks lie
Mistake 3: Shaking the vial during reconstitution Shaking creates foam, introduces air bubbles into the solution, and can denature the peptide through mechanical stress
That number is not a typographical error
