How much bacteriostatic water to add to a Selank vial, what concentration that gives, and how many units to draw on a U-100 insulin syringe for your dose.
The total mg of compound in the vial as labelled by the supplier.
How much sterile bac water you'll add to reconstitute the vial.
How much of the compound you want to take per injection.
U-100 syringes use the standard 100 units = 1 ml gradation.
Take a 10 mg vial of Selank and the catalogue's typical dose of 250 mcg. Add 3 ml of bacteriostatic water and the vial holds 3.33 mg/ml, so one dose is 7.5 units on a U-100 insulin syringe.
At once daily over 8 weeks that is 56 doses and 14 mg in total — 2 vials of 10 mg. One vial covers about 40 days at that rate, which is longer than the ~28 days a reconstituted peptide keeps in a fridge — a smaller vial wastes less. Storage on record — Reconstituted: 2-8°C, use within 30 days
