Overview
GenX is a research peptide supplier established in 2017, making it one of the longest-running suppliers tracked on PepLookup. They offer independently tested compounds with cGMP manufacturing standards, shipping to both the U.S. and Canada via USPS Priority or UPS. International flat-rate shipping is available at 8 to 20 business days.
Highlights
Researchers choose GenX for their established track record since 2017, cGMP manufacturing standards, and international shipping including Canada. Their longevity in the market provides a reliability signal that newer 2025 and 2026 entrants cannot match. The cGMP manufacturing claim is a stronger quality standard than most competitors reference.
Comparison
GenX is one of the most established suppliers in the market, operating since 2017 when most competitors launched in 2025 or 2026. Their cGMP manufacturing and international shipping set them apart. They do not currently list a coupon code, and payment is limited to credit cards. Use the price comparison table above to compare per-mg pricing.
