Peptides ship as a lyophilised (freeze-dried) powder inside a sealed vial. To inject one, you reconstitute it by adding bacteriostatic water (BAC water) to the vial. The amount of water you add determines the concentration — more water = more dilute, less water = more concentrated.
Most peptide users draw doses with insulin syringes measured in units (1 unit = 1/100 ml on a standard 100-unit syringe). The math:
units per dose = (desired mcg) / (mcg per ml ÷ syringe units)
Get it wrong by a factor of 10 and you've either underdosed significantly or overdosed dangerously. This calculator removes the maths error.
