Frequently Asked Questions
What is Melanotan II peptide?
Melanotan II is a synthetic analogue of alpha-melanocyte-stimulating hormone (alpha-MSH), studied for its activity at melanocortin receptors involved in melanogenesis research. Peptalix Labs supplies Melanotan II 10mg at 99.73% purity, confirmed by Freedom Diagnostics.
What purity is Peptalix Labs Melanotan II 10mg?
Independently batch-tested at 99.73% purity by Freedom Diagnostics using HPLC-UV and mass spectrometry. Net peptide content 9.68 mg per vial, Lot 120-A-S, Accession #2604200480.
What is the difference between Melanotan I and Melanotan II?
Melanotan I (Afamelanotide) is a linear alpha-MSH analogue studied for selective melanocortin-1 receptor activity. Melanotan II is a cyclic analogue studied for broader melanocortin receptor activity, including MC1R and MC4R pathways.
How is Melanotan II peptide stored?
Supplied as white lyophilised powder. Store the sealed vial at -20C prior to reconstitution. Once reconstituted with bacteriostatic water, store at 2-8C and use within 28 days.
How do I reconstitute Melanotan II 10mg?
Draw the desired volume of sterile bacteriostatic water into a fresh syringe and inject slowly down the inner wall of the vial. Gently swirl until fully dissolved. Never shake.
What research has been published on Melanotan II?
Melanotan II has been studied in melanocortin receptor research examining melanogenesis pathways and structure-activity relationships of alpha-MSH analogues.
Can I buy Melanotan II peptide online in the USA?
Yes. Peptalix Labs offers Melanotan II 10mg for purchase online for qualified USA researchers. COA-verified, GMP-sourced, same-day shipping.
Does Peptalix Labs ship Melanotan internationally?
Yes, to Canada, Australia, the United Kingdom and most of Europe, with tracked delivery in 5-12 business days.
What is the appearance of Melanotan II 10mg?
White lyophilised freeze-dried powder, as confirmed in the Freedom Diagnostics COA.
Is Melanotan II peptide legal to buy in the USA?
Yes, as a research chemical for qualified researchers conducting in-vitro laboratory studies. Not FDA-approved for human use. Sold strictly for research purposes.
What is the research dosage range for Melanotan II?
Published Melanotan II research has used varying dosing parameters depending on study model. Peptalix Labs does not provide dosing guidance, as our products are sold for research use only.
Which lab verified Peptalix Labs Melanotan II purity?
Freedom Diagnostics, a US-based independent laboratory operated by Principal Chemist Alex Johnson. Accession #2604200480.
What is Melanotan peptide before and after research used for?
This phrase typically refers to consumer-context photographic comparisons, which fall outside the scope of in-vitro laboratory research. Peptalix Labs supplies Melanotan strictly for research purposes, not for cosmetic or human-use protocols.
Can Melanotan II be studied alongside PT-141?
Yes. Melanotan II and PT-141 (Bremelanotide) are both melanocortin receptor analogues frequently studied together for comparative receptor-subtype research.
What other skin and anti-aging research peptides does Peptalix Labs offer?
Our skin and anti-aging category includes GHK-Cu, Snap-8, Epitalon, and the other Melanotan variant — all COA-verified and GMP-sourced.
