Scraped precisionresearchlabs.com (redirect target of the vendor's precisionpeptideco.com). CAVEAT: Finnrick's primary link precisionpeptidesusa.com is a different-looking shop (Precision Peptides USA, FL, registered 2025-10-31, 16 products, single vials $77-354) — not included; see module docstring. Product HTML is login-walled ('you must register an account') but the public Store API answers. Prices are the sale price (regular price crossed out). Volume tiers ('Buy more, save more!', applied in cart, read from a throwaway Store API cart): qty 2 / 3 / 5 / 10 of a line -> about 5% / 10% / 15% / 20% off the sale price (BPC-157 $34.99 -> $33.24 / $31.49 / $29.74 / $27.99). Every cart auto-adds a free bacteriostatic water + silicone cap.

Thymosin Alpha-1, Selank and 'BPC 157' listings state no vial dose (amount None). Each SKU is one vial. Supplies (caps, case, syringes, reconstitution kit) skipped; bacteriostatic water kept.
