Triptorelin
Summary
GHK-Cu is a naturally occurring copper complex that declines with age. It is one of the most studied anti-aging peptides, known for powerful skin rejuvenation, wound healing, and tissue remodeling effects.
Triptorelin is a synthetic decapeptide analog of gonadotropin-releasing hormone (GnRH) with 100x the potency of native GnRH. An FDA-approved drug (Trelstar) for prostate cancer and precocious puberty, it is also used in post-cycle therapy (PCT) to rapidly restart the hypothalamic-pituitary-gonadal (HPG) axis after anabolic steroid suppression.
