Generic Peptides Melanotan II 5 mg and 10 mg Research Vials

Generic Peptides Melanotan II 5 mg and 10 mg Research Vials

Generic Peptides Melanotan II is the cyclic analogue of alpha-melanocyte stimulating hormone, supplied as lyophilised 5 mg and 10 mg vials. It binds the melanocortin receptors MC1, MC3 and MC4 without selectivity, so the same compound is associated with pigmentation and with central appetite and libido effects in the research literature. No regulator has approved it as a medicine, and Melanotan II for sale here comes from a GMP manufacturer with a Certificate of Analysis on file.

• Melanotan II (MT-II) - 5 mg or 10 mg per lyophilised vial
• Cyclic alpha-MSH analogue, non-selective MC1, MC3 and MC4 agonist
• No human half-life confirmed; reviews cite about 1 to 2 hours
• GMP-manufactured, HPLC-verified, COA on file per batch

Variant Comparison

Both options contain the same peptide and differ in how much powder the vial holds.

A 5 mg vial with 2 ml of solvent gives 2.5 mg per ml, and a 10 mg vial with the same 2 ml gives 5 mg per ml, so identical syringe volumes hold double the amount in the larger vial.

How Melanotan II Works

Melanocortin receptors sit in the skin, the gut and the brain. Signalling at MC1 drives melanin production, which is the pigmentation side that gave the peptide its name, while MC4 signalling in the central nervous system influences appetite and sexual response. Published human work used subcutaneous dosing: the 1996 pilot study started at 0.01 mg per kg and escalated in 0.005 mg per kg steps to 0.025-0.03 mg per kg, and a later study ran single ascending doses from 0.03 to 1.5 mg per kg to describe tolerability. Both are study designs rather than protocols.

Reconstitution and Storage

Add bacteriostatic water down the vial wall without shaking. Keep the powder cold and dry and the reconstituted solution at 2-8 C, and do not freeze it. The same handling applies to the other melanocortin peptide on this line, PT-141, and to the older Melanotan II listing with its own vial size.

Quality & Authenticity

Batches are produced under GMP conditions and checked by independent HPLC, with the Certificate of Analysis kept for the batch. Reported effects are gastrointestinal and vascular: nausea and vomiting were dose dependent and appeared at most dose levels in the pilot study, and flushing and facial redness are described frequently. Regulators have warned about unapproved tanning products containing this peptide, and as an unapproved substance it falls under class S0 of the WADA prohibited list.

Consult a healthcare professional before any cycle. Where a stack suppresses natural testosterone, PCT is required. Doses are common community protocols.
