02 — Reconstitution

How to reconstitute peptides

1
Bring vials to room temperature
Let the lyophilized peptide vial sit out for 5-10 minutes before opening.
2
Add bacteriostatic water
Slowly drip BAC water down the inside wall of the vial — do not inject directly into powder.
3
Swirl gently
Roll between palms. Never shake — agitation can denature the peptide.
4
Calculate your dose
Use our dose calculator to convert mg/mL into syringe units.

03 — Storage & handling

Keep peptides at peak purity

Lyophilized (powder)

Store at 2-8°C in the fridge for up to 24 months. Long-term: -20°C freezer.

Reconstituted

Refrigerated at 2-8°C, use within 28 days. Keep away from light.

Handling

Avoid repeated freeze-thaw cycles. Never shake reconstituted vials.
