PT 141  is the generic term for a research peptide being studied for its possible use in helping to improve sexual dysfunction in both men (erectile dysfunction or impotence) and women (sexual arousal disorder). 
PT 141 was developed from the tanning peptide Melanotan 2, which is a synthetically produced variant of a peptide hormone naturally produced in the body that stimulates melanogenesis that is known as alpha-Melanocyte stimulating hormone. 
MSH, activates certain melanocortin receptors in the process of exerting its effects. 

PT 141 is a synthetic amino acid protein discovered during clinical trials using the Melanotan 2 for sunless tanning, photo-protection results from melanotans. The melanocortin system targets receptors associated with desire through the melanocyte stimulating hormone paths that cross the blood-brain-barrier. Potentially the powerful sex-drug results feeling an aphrodisiac experience amplifying arousal pt 141 reviews have shown the ability to increase libido effects of both men and women

Potential benefits

PT 141 in Men:

• effective in a broad range of patients, including those with severe ED and those non-responsive to sildenafil
• efficacy in "at-home" studies is comparable to PDE-5 inhibitors
• up to 50% of ED patients were restored to a normal level of function
• co-administration with sildenafil shows superior efficacy
• side effects include facial flushing, nausea, aftertaste and post-nasal drip

PT 141 in Women:

Palatin conducted a Phase 2A study in 18 premenopausal women with a diagnosis of female sexual
dysfunction (FSD). Patients reported a significant increase in sexual desire and in genital arousal after
receiving PT 141, compared to
placebo. Additionally, there was a correlation between sexual desire and genital arousal in patients receiving
PT 141, an observation that further reinforces the potential importance of these reports.
