Storage & handling

Before reconstitution

Lyophilized vials keep at 2–8 °C (36–46 °F). For long-term storage, −20 °C is fine. Keep them out of direct light.

After reconstitution

With bacteriostatic water, refrigerate at 2–8 °C and use within 28 days. With plain sterile water there is no preservative — discard within 24 hours.

Never freeze reconstituted vials

Freeze–thaw cycles break down peptide structure. Refrigerate only once liquid.

Mix gently

Aim the bacteriostatic water down the vial wall and roll gently to dissolve. Do not shake.

One sterile needle per injection

New syringe and needle every time. Swab the stopper, rotate injection sites, never share vials.

Verify what is in the vial

A calculator cannot check purity, sterility or identity. Ask for a current Certificate of Analysis (HPLC/MS).

  • These figures are community-reported conventions, not FDA-approved dosing. Where a compound is an approved drug, the approved prescribing information governs.
  • Peptidex cannot verify purity, sterility or identity of anything in your vial — ask your supplier for a current Certificate of Analysis (HPLC/MS).
