Peptide Care Tips
Follow these best practices to ensure maximum efficacy.
Use Bacteriostatic Water Only
Always reconstitute peptides with bacteriostatic water (BAC water) — never saline or sterile water — to preserve sterility.
Never Shake the Vial
When reconstituting, place the vial on a flat surface and gently move it in a slow circular motion. Never lift the base off the surface or shake it — this can denature the peptide.
Refrigerate After Reconstitution
Once reconstituted, store the vial in the refrigerator (36–46°F / 2–8°C). Use within 21 days to ensure maximum efficacy.
Freeze Lyophilized Peptides
Unreconstituted (lyophilized) peptides can be stored in a freezer for up to 2 years. Keep them sealed and away from moisture.
Avoid Direct Sunlight
Peptides are light-sensitive. Always store vials in a dark place or wrapped in foil to prevent degradation.
Let It Reach Room Temp
Remove the vial from the fridge 5–10 minutes before use. Let it reach room temperature before starting research.

Yes, all our compounds undergo rigorous third-party testing to verify their purity and molecular identity. We provide independent Certificates of Analysis (COA) for every batch, confirming a purity standard of 99% or higher.
Delivery times vary by destination and the shipping method you choose at checkout. Every order ships with tracking, and you'll receive a tracking number by email once it's on the way.
Lyophilized (freeze-dried) powder should be stored in a freezer at -20°C for long-term stability (up to 2 years). Once reconstituted with bacteriostatic water, vials must be refrigerated at 2-8°C (36-46°F) and used within 21 days.
Yes. Lyophilized peptides are highly stable at room temperature for several weeks during transit. However, we recommend storing them in the freezer immediately upon receipt.
We offer discounted bulk packages directly on each product page (Buy 3 and Buy 5+ tiers). For larger wholesale quantities or custom formulation inquiries, please contact our support team.
When stored in a freezer at -20°C, unopened lyophilized vials remain stable and maintain full potency for up to 2 years from the manufacturing date.
