Reconstitution
Also known as: recon · mixing
The process of dissolving a lyophilized peptide powder in bacteriostatic water or saline to produce an injectable solution.
Proper reconstitution technique: swab both vial tops with alcohol, draw BAC water into an insulin syringe, inject the water down the side of the peptide vial wall (not directly onto the powder puck to prevent foaming), swirl gently without shaking, and allow to fully dissolve before drawing doses. Shaking a peptide vial denatures some compounds — gentle swirling or simple room-temperature dissolution is preferred.
Reconstitution volume determines final concentration and therefore dose units per injection. DoseCraft's reconstitution calculator converts target dose in mcg or mg to insulin syringe units at arbitrary reconstitution volumes.
A 5mg Semaglutide vial reconstituted with 2mL BAC water yields 2.5mg/mL. A 0.25mg dose equals 0.1mL, which is 10 units on a standard U-100 insulin syringe.

BAC Water
Sterile water containing 0.9% benzyl alcohol, used to reconstitute lyophilized peptides for multi-dose vial use.
Concentration (mcg/mL)
The amount of peptide mass per unit volume of reconstituted solution, typically expressed as micrograms (mcg) or milligrams (mg) per milliliter.
Units (Insulin Syringe)
The volumetric graduations on a U-100 insulin syringe, where 100 units equals 1mL of solution.
Drawing Dose
The technique of extracting a measured dose of reconstituted peptide from the vial into an insulin syringe.
