Sobre PT-141 (Bremelanotide)
Buy PT-141 (Bremelanotide) 10mg at IGF1 Shop. PT-141 is a synthetic cyclic heptapeptide derived from Melanotan II by replacing the C-terminal amide with a free carboxylic acid. This single change shifts receptor selectivity away from MC1R (melanogenesis) toward MC4 and MC3 receptors, producing distinct effects on sexual response pathways without significant tanning activity. Each PT-141 10mg vial is HPLC-verified at ≥99% purity, ESI mass-spec confirmed against the theoretical 1,025.18 Da molecular weight, and accompanied by a per-lot Certificate of Analysis. CAS 189691-06-3.

FAQ
PT-141 (Bremelanotide) — Perguntas frequentes
What is PT-141?
PT-141 (Bremelanotide) is a synthetic cyclic heptapeptide derived from Melanotan II by replacing the C-terminal amide with a free carboxylic acid. This change shifts receptor selectivity toward MC4 and MC3 receptors, producing effects on the sexual-response pathway without significant melanogenic activity. CAS 189691-06-3.
What is the standard PT-141 dose?
The standard PT-141 dose is 1.75mg subcutaneously, taken at least 45 minutes before activity. Maximum one dose per 24 hours, no more than 8 doses per month. A 10mg vial reconstituted with 1mL bacteriostatic water yields 1mg per 0.1mL — so a 1.75mg dose equals 0.175mL (17-18 units on a U-100 insulin syringe).
How fast does PT-141 work?
Onset is typically 30-60 minutes from subcutaneous injection, with peak effect at 2-4 hours and duration up to 8-12 hours. Effect varies by individual.
What side effects are common with PT-141?
The most frequently reported are mild facial flushing, transient blood pressure elevation, and nausea — particularly at first dose or higher doses. Effects typically attenuate with subsequent doses.
How is PT-141 tested?
Each PT-141 lot is HPLC-tested to ≥99% purity, ESI mass-spec confirmed, and LAL endotoxin tested below 0.5 EU/mg. ISO 17025-accredited third-party labs perform the testing.
How do I store PT-141?
Lyophilized PT-141 is stable at -20°C for 24+ months. After reconstitution with bacteriostatic water, store refrigerated at 2-8°C and use within 30 days.
