Why hand delivery matters

Research peptides ship as a freeze-dried powder, so they travel without a cold chain and a shipped vial is not a compromised one. What local delivery removes is handoffs: four carrier legs become none, and the lot goes from our shelf to your bench with nobody in between.

It also means you can check what you are getting before it changes hands — same lot number, same published certificate, in your hand.

Arranging it

Send us what you need and choose local pickup on the form. We confirm what is in stock and arrange a time. Materials are supplied to qualified researchers for laboratory use only.
