We also typically recommend cycling peptides, using them for a set period followed by a break, to maintain the bodys sensitivity and maximize results over the long term
For athletes, this means more training volume without hitting the wall , faster turnaround between sessions, and a metabolic environment that supports both performance and physique goals
This changes the peptide's structure and how it interacts with cell receptors, leading to possible variations upon comparing the effects of GHK-Cu vs AHK-Cu on the body
