Storage Guide

Before and after reconstitution
🧊 Storage Conditions by State
Compound State Temperature Duration Key Notes
Lyophilised powder (unopened) Room temp or fridge 12–24 months Keep away from direct light and moisture. Freezing lyophilised powder is acceptable for long-term storage beyond 12 months. Bring to room temperature before reconstituting.
Reconstituted in BAC water Refrigerate 2–8°C 4–6 weeks The bacteriostatic preservative in BAC water allows multi-week refrigerated storage. Keep away from the back of the fridge (freezing point risk). Never freeze a reconstituted vial — the freeze-thaw cycle degrades the peptide.
Reconstituted in plain sterile water Refrigerate 2–8°C 24–72 hours only No preservative means rapid bacterial growth risk. Use BAC water for any multi-dose vial. Plain sterile water is only appropriate for single-dose preparations used immediately.
GLP-1 peptides (Semaglutide, Tirzepatide) Refrigerate 2–8°C 4–6 weeks reconstituted Particularly temperature-sensitive. Keep in a designated section of the fridge away from the door (temperature fluctuates). Do not leave at room temperature for more than 30 minutes before injection.
Cerebrolysin (pre-filled ampoules) Refrigerate 2–8°C Per manufacturer date Genuine Cerebrolysin (Ebewe Pharma) requires continuous cold chain. Do not accept product that has been shipped without cold packs. Check ampoules for any colour change — should be pale yellow/straw coloured.
GHK-Cu (copper peptide) solutions Refrigerate 2–8°C 3–6 months topical Copper peptides are more stable than most peptides but still benefit from refrigeration. Protect from UV light — use opaque or amber containers. Topical preparations: keep away from oxidising agents.
Epitalon (reconstituted) Refrigerate 2–8°C 4 weeks Standard reconstituted storage. Epitalon is typically used in 10-day intensive courses — reconstitute at the start of the course and complete within the storage window.
Date everything. Write the reconstitution date on every vial in permanent marker. If you cannot remember when you reconstituted something, do not use it. The cost of a fresh vial is substantially lower than the cost of treating an infection from a contaminated one.
