Peptide reconstitution matrix
Syringe units to draw for common doses, by vial size and water volume. Every value is arithmetic over the vial and the water; none is a dose recommendation.
Reconstitution turns a vial of dry powder into a solution of known strength. The concentration is the vial content divided by the water added: a 5 mg vial with 2 mL of water holds 2.5 mg per mL.
On a U-100 syringe each unit is 0.01 mL, so the units to draw for a dose are the dose divided by the concentration, times 100. The matrix does that for the vial sizes and water volumes people most often use.
A cell marked n/a is a draw above 100 units, which a 1 mL syringe cannot hold in one injection.
| Vial | Water | mg/mL | 250 mcg | 500 mcg | 1 mg | 2.5 mg | 5 mg |
