About This Crownwell Research Code
PeptideStack tracks active peptide vendor savings pages so researchers can find current checkout offers without sorting through stale coupon sites. For Crownwell Research, the tracked offer is code-based: code PSTACK applies an exclusive discount at checkout, and starting from the tracked link on this page attaches the PeptideStack referral to your visit.
One thing to know up front: Crownwell Research also runs its own public promotions. At the time of writing, the site advertises 15% off your first order for signing up to its newsletter, a 10% research referral program, and a 15% off banner promotion. We have not verified that PSTACK stacks with any of those vendor offers, so the practical move is simple — apply the codes you have, compare the cart total each way, and complete checkout with whichever saves you more.
Crownwell Research runs a 44-product WooCommerce catalog priced in USD, and access to it is now account-gated: as of September 18, 2026 the storefront root, /shop, and our own tracked referral link all redirect to the vendor's website-registration page, which asks what type of researcher you are and carries a 21+ and research-use-only confirmation — so plan on registering and signing in before any product or price is visible. Healing staples anchor the range: BPC-157 on its own and the BPC-157/TB-500 Wolverine blend, alongside CJC-1295 (No DAC), Cagrilintide, GHK-Cu, Epithalon, AOD9604, bioregulators like Cortagen, and Glutathione. The store's GLP-class products are listed under the vendor's own names — GLP1-Sema, GLP2-Tirz, GLP3-Reta, and GLP3-R — and we refer to them exactly as the vendor labels them. Two distinctive touches: Crownwell sells multi-vial kits, from a 10-vial GLP3 kit at $295 up to larger kits at $1,250, and carries intranasal solutions like a Selank spray alongside standard vials, plus bundles such as the Bioregulator Trio. The listed prices already on this page, such as BPC-157 at $38.00 and GHK-Cu from $29.00, were recorded while the catalog was still publicly browsable — treat them as illustrative examples and confirm current pricing after you log in.
On the quality side, Crownwell Research states its peptides are 99% purity and 3rd party tested, maintains a COA Library on the site, and publishes a research-use-only policy. Those are the vendor's own claims and documents — review the COA for your specific batch before ordering. On logistics, the vendor states it does not ship internationally, so plan on a US delivery address, and confirm current shipping terms at checkout.
