Bulk Peptides

Our bulk peptides are the best-selling compounds offered in packs of 50, 100 or 200 vials (up to 300 for ipamorelin), plus 10-packs of IGF-1 LR3 and IGF-1 DES and semaglutide in 10, 30 and 50 vial packs. Each vial is sealed and labeled separately, at a much lower price per vial than buying singles.

What are bulk peptides?

Bulk buying makes sense for labs running long or large studies, for groups that share stock, and for resellers. Every vial in a bulk pack is the same product as the single listing, sealed individually so you only open what you need.

Freeze-dried peptides keep well in the freezer, so a bulk pack bought now can last through a long project if it’s stored properly.

Purity and testing for our bulk peptides

Each product page shows the tested purity for the current batch, measured by HPLC with mass spectrometry, and most of our peptides test at 99% or higher. Every vial is labeled with the compound, the amount and a batch number. The certificate of analysis is filed under that number, and we’ll email it to you on request.

Store sealed vials in the freezer, or the fridge for shorter stretches, and reconstitute with sterile bacteriostatic water. Every vial page lists the concentration you’ll get for each volume. Our vial storage case keeps ten vials upright and together.
