Peptides

Molecules that
drive biology.

01 — What they are

High-precision biological messengers

Peptides are short chains of amino acids that signal specific processes in the body with a precision few molecules can match.

02 — How they work

Targeted and controlled responses

They bind to specific receptors and trigger precise responses: recovery, performance, metabolism and cellular optimisation.

03 — Why purity matters

Verifiable molecular consistency

Purity ensures every molecule interacts as expected. No impurities, no variables. Only reproducible science.

Storage and
handling.

01 — On arrival

Delivered cold

Lyophilised powder ships in insulated, temperature-controlled packaging to protect molecular integrity in transit.

02 — In the lab

Store at −20 °C

Keep sealed vials frozen until use. Reconstitute with bacteriostatic water and follow standard peptide handling practice.

03 — Quality

HPLC-tested before dispatch

Every batch is analysed by HPLC and released only once it meets the purity specification for that compound.
