Hormonal & Metabolic
Peptides that interact with growth hormone axes, thyroid function, and metabolic regulation.
GH-axis peptides like Ipamorelin and CJC-1295 are the main hormonal players in this library. Unlike anabolic steroids, they work by stimulating your pituitary's own GH production rather than replacing it — making them significantly safer with proper cycling.
