How we read this shop
https://penguinpeptides.com/shipping-policy/ ('Shipping within United States only'; adult signature over $700); rates/payment methods read from a throwaway Store API cart to a US address: $12 flat, free USPS Priority at a $50 subtotal (not at $42); quantity tiers from product pages.
Store API cart works but /checkout/ redirects to /my-account/ (login or free self-registration required before checkout); cart gateways NMI, Cash App, Klarna, Afterpay, Zelle, Link Money.
WooCommerce Store API via the generic adapter. Doses missing from some product names (LL37, VIP, DSIP, Sermorelin, AOD9604, IGF-1 LR3, Ara-290, HMG, MT-2, Lipo-C, 'Melanotan' = Melanotan 1 10mg) are taken from the product description; FOXO4-DRI and DiHexa have no description and no dose anywhere -> amount None. Codes decoded only where the site says so: GLP-3 R = Retatrutide ('GLP-3 R 10mg (Reta)'), GLP-1 C = Cagrilintide, GLP-1 M = Mazdutide. 'GLP-1 T' and 'GLP-1 S' are never decoded on the site (product pages, lab results) so they are left as-is. Every SKU is a single vial. Peptide Case, T-Shirt and acetic acid dropped. Product pages show per-product quantity tiers (5-9 units -5%, 10-15 -10%, 16-20 -15%, 21+ -20%) not reflected in row prices; banner coupon RESEARCH30 (30% off + free peptide per $150) is a coupon, not applied. Plain requests to product pages get 403 (Store API is open).
