PT-141 10 mg vials - In Stock
PT-141 (Bremelanotide) is a brain-acting libido booster approved for low sexual desire in women, and used off-label in men for increased sexual interest and arousal. It differs from ED drugs by targeting desire, not just function.
PT-141, also known as Bremelanotide, is a synthetic peptide developed primarily to enhance sexual arousal and desire. It’s derived from Melanotan II, but is designed to target sexual function specifically, without the tanning effects.
