One. Remove peptide vial cap and swab the rubber stopper with alcohol.
Two. Draw the desired volume of bacteriostatic water into the syringe.
Three. Inject slowly against the vial wall. Never spray directly onto the lyophilized cake.
Four. Gently swirl to dissolve. Do not shake.
Five. Label the vial: compound, concentration in mg/mL, date reconstituted.
Six. Store at 2 to 8 degrees Celsius. Most peptides remain stable 28 to 30 days refrigerated.
U-100 1.0 mL. 100 units total. Each small mark is 2 units, equal to 0.02 mL.
U-100 0.5 mL. 50 units total. Each small mark is 1 unit, equal to 0.01 mL. Best for doses under 0.5 mL.
U-100 0.3 mL. 30 units total. Each small mark is 0.5 unit, equal to 0.005 mL. Best for micro-dosing.
Reading. Hold the syringe at eye level. Read the flat edge of the plunger stopper closest to the needle.
Lyophilized. Store at minus 20 degrees Celsius for long-term, 2 to 8 degrees Celsius for short-term. Protect from light.
Reconstituted. Refrigerate at 2 to 8 degrees Celsius. Use within 28 days unless compound-specific data extends the window.
Bacteriostatic water. Room temperature is acceptable. USP guidance is 28 days after first puncture for multi-dose vials.
Never freeze reconstituted peptides. Ice crystal formation denatures peptide structure.
Locked Spec. Reconstitution volume is taken directly from a Pivotal locked specification file. Examples include GLOW and KLOW.
Passdown. Reconstitution volume is taken from prior published clinical literature commonly referenced for that peptide.
Unverified. No Pivotal-locked volume exists. The default shown is a study aid only. Verify the volume before any clinical application.
