Melanotan II 5 mg vial

Prices from 3 vendors, and how much to draw for the commonly cited doses.

Read the regulatory status before you compare prices.

Not approved in any country and not permitted in pharmacy compounding. The UK regulator issued a public warning in 2009 and the FDA has sent warning letters to US distributors. Published case reports link it to melanoma, eruptive and atypical moles, ischemic priapism requiring surgery, muscle breakdown, kidney infarction, and a serious brain condition called posterior reversible encephalopathy syndrome. Whether it directly causes melanoma is unresolved, since users also tend to seek more sun, but the mole changes are consistently documented. Separately, testing of gray-market vials found actual peptide content ranging from about 4.3 to 8.8 mg in vials labelled 10 mg, so the dose you think you are taking may not be the dose you are taking.

How to mix a 5 mg vial

Find the column for the amount of water you added to the vial. The number is how far to draw on a U-100 insulin syringe, where 100 units is 1 mL. This is arithmetic on the label, not a recommended dose.
