Alpha-MSH is the parent peptide behind the melanocortin anti-inflammatory pathway, backed by 6,500+ published studies. Two FDA-approved drugs target the same receptor family. Native alpha-MSH's 20-minute half-life limits practical use; most users choose KPV, its active C-terminal fragment, for anti-inflammatory applications instead.

Alpha-MSH is not a community peptide. It's a research reference compound, and the practical realities reflect that. Most people looking for melanocortin anti-inflammatory effects should consider KPV first; it's cheaper, more stable, and doesn't cause pigmentation. Reconstitution math for a 1 mg vial: add 2 mL bacteriostatic water. That gives you 500 mcg/mL, or 5 mcg per unit on a 100-unit insulin syringe. A 100 mcg beginner dose is 20 units. A 250 mcg moderate dose is 50 units. For a 5 mg vial with 2 mL BAC water: 2,500 mcg/mL, or 25 mcg per unit. A 250 mcg dose is 10 units. A 500 mcg dose is 20 units. The 5 mg vial is better value if you're running a full 8-week protocol. Alpha-MSH degrades faster than most peptides after reconstitution. Keep it at 2 to 8 degrees Celsius and use within 14 days. Don't freeze and thaw repeatedly. If the solution goes cloudy, throw it out.

Expect to pay $80 to $250 per milligram for genuine research-grade product.
