99%+ purity — HPLC verified with independent CoA

Shipped as Lyophilized (Freeze-Dried) Powder

Our peptides are shipped as a lyophilized (freeze-dried) powder because they are highly unstable in liquid form. Lyophilization removes almost all the water, preserving the peptide’s delicate structure and greatly extending its shelf life during transit.

To use a lyophilized peptide, it must be dissolved (reconstituted) using a sterile liquid, such as bacteriostatic water or saline, depending on the specific application.

After Reconstitution — Storage Guidelines

Refrigerate immediately

Store reconstituted peptides at 2–8°C. Never leave them at room temperature.

BAC water extends shelf life

Peptides reconstituted with bacteriostatic water typically remain stable for 4–6 weeks at 2–8°C.

Sterile water has a shorter window

If reconstituted with plain sterile water, use within 48 hours or freeze in single-use aliquots.

Avoid freeze-thaw cycles

Repeatedly freezing and thawing a reconstituted peptide causes degradation. Divide into single-use aliquots first.
