This calculator converts micrograms (mcg) into syringe units based on how much peptide is in your vial and how much water you added.
This tells you how far to pull the plunger — not how much peptide to take

Before Reconstitution (Dry / Lyophilized)
Pro Tip: Don’t store on a counter ‘for convenience’—light + heat are the enemy.
Most peptides use bacteriostatic water (0.9% benzyl alcohol) however some specify using acetic acid.
23–25g needles draws smoothly for both solution types. 2ml of solution works well for most applications.
Keep control of plunger during the process as the vacuum created can pull the solution fast from syringe.
Roll the vial between fingers or let sit to dissolve naturally. Never shake
