Main Peptides is a site-verified vendor that serves both retail and bulk buyers, offering around 30 peptides. While the vendor lists prices on nearly all products, its COA documentation is limited—a few reports are hosted, but none currently map to the active catalogue. No community reports are available yet, leaving buyer experiences with product quality, shipping, and service unknown. The vendor does not publicly specify its location or shipping regions.

Testing coverage
We hold lab certificates for this vendor, but none of them correspond to a product currently in their catalogue — so we cannot confirm what is in any vial you could actually buy. Testing scores zero until that mapping exists. This one is on us as much as them.
