Peptide.Promo

Peptide.Promo is a price-comparison directory for research peptides, helping buyers compare listings from multiple vendors using normalized cost per milligram. Because the same peptide may be sold in different vial sizes, the service converts each listing into a comparable $/mg figure rather than relying on sticker price alone. It also provides a dose calculator, vendor coupons and clearly labelled sponsored placements.

The directory tracks 66 peptides across 52 vendors, with 1,929 live prices refreshed daily and more frequent updates for featured vendors. Listings can be compared side by side across products such as BPC-157, GHK-Cu, NAD+, Semax, MOTS-c, TB-500, Semaglutide and Tirzepatide. Each result includes the current price-per-milligram, the number of available offers and the vendor offering the displayed price.

Peptide.Promo organizes its catalog into categories including Weight Loss, Growth Hormone, Healing & Recovery, Muscle & Performance, Skin & Beauty, Brain & Focus, Anti-Aging & Longevity, Sexual Health and Bioregulators. Vendor pages include tracked product counts, traffic estimates, ratings and, where available, payment methods such as credit cards, ACH, bank transfer, cryptocurrency, Google Pay and Apple Pay.

All listed products are identified as being for laboratory and research use only, not for human consumption, and the service does not provide medical advice or sell peptides directly. Users are advised to confirm pricing on the vendor’s own website before purchasing. Peptide.Promo may earn affiliate commissions from vendor referrals, without changing the customer’s price or the ranking methodology.
