Key Research Areas:
- Sexual Function & Libido Enhancement
A melanocortin receptor (MC3R/MC4R) agonist developed from Melanotan II, PT-141 acts on the central nervous system to enhance sexual desire and arousal. It is FDA-approved for the treatment of hypoactive sexual desire disorder (HSDD) in premenopausal women and studied for erectile dysfunction in men, particularly when unresponsive to PDE5 inhibitors. - Neuroendocrine & CNS Mechanisms
Unlike PDE5 inhibitors, which act peripherally on vascular smooth muscle, PT-141 exerts its effects via central melanocortin pathways in the hypothalamus, offering a distinct mechanism for modulating sexual behavior and arousal. - Erectile Dysfunction (ED)
Investigated as a therapeutic option for men with ED, including those with cardiovascular disease or diabetes, where standard treatments may be less effective. - Female Sexual Dysfunction (FSD)
Demonstrated efficacy in clinical trials for increasing sexual desire, arousal, and satisfaction in women with HSDD, leading to its regulatory approval. Research continues into applications for postmenopausal women and other subtypes of FSD. - Mood, Stress & Behavioral Effects
Melanocortin signaling is linked to mood regulation and stress response. Early studies suggest PT-141 may have ancillary effects on mood and anxiety, though this remains an emerging area of research. - Energy Balance & Metabolic Pathways
As a melanocortin receptor agonist, PT-141 may influence appetite, energy expenditure, and body weight regulation, connecting it to broader metabolic research. - Pain Modulation & Inflammation
Preclinical findings indicate melanocortin agonists, including PT-141, may exert analgesic and anti-inflammatory effects, warranting further investigation for chronic pain syndromes.
- Product Care and Storage – All products are shipped using the Lyophilization process, which ensures that products remain stable for shipping for up to 3-4 months. Products must be reconstituted to a liquid, by mixing with bacteriostatic water for research and testing.
- Lyophilized or powder form – Store in cool, dry place away from light; can be stored at room temperature. Remains stable for several weeks or more.
For long term storage (months to years) freezing is optimal to preserve stability and maintain integrity. - Reconstituted form – Refrigerate under 39F; peptides will remain stable for up to 30 days.
- Usage – We are unable to provide any dosing instructions, however all products should be considered pharmaceutical grade.
- Disclaimer – This product is for research use only and is not intended for human consumption, diagnostic use, or clinical treatment. Proper laboratory safety protocols should always be followed when handling peptides.
