Add 2 mL BAC water to your 10 mg vial. Draw to 100.0 units on a U-100 syringe for a 5mg dose. This vial will last 2 doses.
Copy link saves these numbers in the address. Anyone who opens it sees the same draw.

MIF-1 (melanostatin, PLG) is an endogenous tripeptide that allosterically modulates dopamine D2 and D4 receptors. One small double-blind trial showed an 89% antidepressant responder rate, but no replication exists. Used in short 5 to 7 day subcutaneous courses for anhedonia.

Reconstitution math matters here because the vial sizes and standard dose create specific syringe calculations. For a 10 mg vial, add 1 mL bacteriostatic water to get 10 mg/mL. Your full 10 mg dose is the entire 1 mL syringe (100 units on an insulin syringe). A 5 mg starter dose is 50 units. Don't use the calculator default of 2 mL; that gives you 5 mg/mL and you'll underdose if you're not recalculating. For a 50 mg vial, add 2 mL bacteriostatic water for 25 mg/mL. Each 10 mg dose is 0.4 mL (40 units). That gets you five 10 mg doses per vial, which covers one full course. The non-obvious thing most beginners miss: MIF-1 is NOT the same molecule as MIF (macrophage migration inhibitory factor). When reading forums or ordering, confirm CAS 2002-44-0 and the sequence Pro-Leu-Gly-NH2. The naming collision causes real confusion in search results and vendor listings. Sourcing is the biggest practical problem. Only 1 to 2 verified US vendors carry it. Order enough for 2 to 3 cycles before starting; supply disruptions have left users stranded mid-protocol.
