32mg multi-dosage injection pen. GIP, GLP-1 & glucagon receptor agonist for subcutaneous injection. For research and analytical purposes only.

Two UK research retatrutide pens compared. Alluvi lists a lower price and claims a high Janoshik purity on its brand site; Body Pharm publishes a full HPLC Certificate of Analysis on every product page. Here is the factual side-by-side — Alluvi figures are from its UK distributor Synedica (captured 6 July 2026); verify current details before ordering.

Alluvi details as listed on their site (captured 6 July 2026). Prices and specifications change — verify current details with the seller before ordering.
Body Pharm publishes a full HPLC Certificate of Analysis on the product page (98.75–99.3% purity, plus sterility, endotoxin, pH and phenol testing). Alluvi claims 99.38% (Janoshik) on its brand marketing site, but no COA is shown at the Synedica point of sale.
Both are sold as pre-filled multi-dose pens (Body Pharm confirmed; Alluvi's pen format is a brand-site claim not stated on the distributor page). Neither needs reconstitution.
Alluvi's 40 mg is cheaper per mg (£3.50/mg vs Body Pharm's £5.00/mg on the 64 mg pen). If lowest price is the priority, Alluvi leads; if verifiable on-page documentation is, Body Pharm does.
Alluvi is cheaper per mg and advertises a high Janoshik purity figure on its brand site. Body Pharm's case is verifiable transparency: a full HPLC Certificate of Analysis published on the product page itself (purity plus sterility and endotoxin testing), where Alluvi shows no COA at its UK point of sale. Choose Alluvi for the lower price; choose Body Pharm if you want documented purity you can read before you buy.
