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.
