Melanotan II vs PT-141
Two melanocortin peptides with overlapping origins and different research profiles.
What is the difference
Melanotan II and PT-141 (bremelanotide) are both melanocortin peptides developed from the same research lineage. PT-141 is a metabolite of Melanotan II, but they differ in receptor selectivity and the research questions they address.
| Property | Melanotan II | PT-141 (Bremelanotide) |
|---|---|---|
| Origin | Synthetic analogue of alpha-MSH | Metabolite/derivative of Melanotan II |
| Receptor profile | MC1R, MC3R, MC4R, MC5R | Primarily MC4R |
| Common format | 10 mg lyophilized powder | 10 mg lyophilized powder |
| Research focus | Pigmentation and melanocortin receptor studies | MC4R-selective signalling studies |
| VND price (this catalog) | 1,000,000 VND | 1,200,000 VND |
Bottom line
Related by chemistry but distinct in receptor profile. The appropriate material depends entirely on the research protocol. Both are listed in this catalog.

Common questions
Which of these peptides is better for research?
Neither is "better" — Melanotan II and PT-141 address different research questions through different mechanisms. The choice depends on the research protocol.
Can I order both peptides from this catalog?
Yes. Melanotan II and PT-141 are listed as separate items. 2+ peptides = free bacteriostatic water 10 ml. Price and availability confirmed before payment.
Do I need a separate inquiry for each peptide?
No. You can ask about both in one Telegram message. Mention the names and formats — the manager will confirm availability, total and timing.
