GenX Peptides
GenX Peptides is one of the longest-running US budget peptide vendors, operating from Houston, Texas since 2013. With over 44 peptides in their catalog, they offer some of the most competitive pricing in the US market. All products are TFA-free and undergo third-party testing via MZ Biolabs using HPLC and mass spectrometry analysis. GenX is known for their affordable pricing on staple peptides like GHRP-2 and GHRP-6 at $20 per vial, and they offer free shipping on orders over $150 with 2-3 business day USPS Priority delivery. While their low prices and long track record make them popular among budget-conscious researchers, international shipping reliability has been reported as inconsistent.
