Sexual Health Peptides

Unlike traditional PDE5 inhibitors that focus on blood flow (vasodilation), PT-141 (Bremelanotide) acts directly on the melanocortin receptors in the brain. This means it addresses the psychological and neurological aspects of libido and desire.

HCG (Human Chorionic Gonadotropin) acts as a luteinizing hormone (LH) mimetic. In a research context, it is used to stimulate the Leydig cells in the testes to produce natural testosterone, which is fundamental for maintaining sperm count and overall sexual drive.

Yes, Melanotan 2 is a non-selective agonist of the melanocortin receptors. While its primary research use is for skin pigmentation (tanning), it significantly activates receptors involved in sexual arousal, often leading to increased libido as a secondary effect.

Oxytocin is a neuropeptide that modulates social interaction and sexual reproduction. It is known to enhance the feelings of relaxation, trust, and psychological stability, which can lead to increased physical sensitivity and a heightened experience during intimacy.

Like most peptides, these should be kept in a lyophilized state in a cool, dark place. Once reconstituted with bacteriostatic water, they must be refrigerated (2-8°C) to maintain their structural integrity and biological activity.
