Strand Bio is a US-only, research-use-only catalog of 29 products launched in 2026. Pricing sits mid-market: across the 28 compounds PepsTracker tracks for them, Strand ranks around the middle of the field and is not currently cheapest on any of them. They are most competitive on AOD-9604 and Thymalin, and least competitive on GLP-1s β Tirzepatide and Retatrutide both sit near the bottom of the field on cost per milligram.
Catalog data comes from their published partner feed, which lists vial size, price and stock status for every product. Shipping is $8.95 standard, free over $150. As of listing they do not publish third-party COAs, so purity and potency are unverified by any outside lab β weigh that against the price.
