Almost all research peptides ship as a fine white powder. That is the result of lyophilisation — freeze-drying — and it is central to why they remain stable.

What lyophilisation does

It removes water from the frozen peptide under vacuum, leaving a dry, stable cake. Without water, hydrolysis and microbial growth essentially stop.

Why it matters for you

Lyophilised vials tolerate room temperature for weeks and ship far more robustly than solutions — which is why a short, cooled transit from Germany is more than enough to protect them.

From powder to solution

When you are ready, reconstitute with bacteriostatic water and refrigerate. See our COA browser for the verified material.
