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

Two pre-filled UK research retatrutide pens, head to head. Both skip the vial-and-reconstitution step. The difference comes down to price per mg and purity documentation: Synedica lists a lower headline price, while Body Pharm publishes a full HPLC Certificate of Analysis for every batch. Here is the factual side-by-side — competitor figures are taken from Synedica's own listing (captured 5 July 2026); verify current details before ordering.

Synedica details as listed on their site (captured 5 July 2026). Prices and specifications change — verify current details with the seller before ordering.
Both are pre-filled multi-dose pens, so neither needs bacteriostatic water or measuring. This is a like-for-like format comparison, unlike the vial sellers that dominate the rest of the market.
Body Pharm publishes a full HPLC Certificate of Analysis per batch — 98.75% (32 mg) to 99.3% (64 mg), plus sterility, bacterial-endotoxin, pH and phenol testing. Synedica states 'pharmaceutical-grade purity' but shows no COA or HPLC report on the product page.
Synedica's 40 mg pen is cheaper on headline price and on price per mg (£4.25/mg vs Body Pharm's £5.00/mg on the 64 mg pen). If lowest cost is the only factor, Synedica leads; if documented purity and dose validation matter, Body Pharm does.
Both are legitimate pre-filled retatrutide pens with free UK shipping. Synedica wins on price — its 40 mg pen is cheaper outright and per mg (£4.25/mg vs £5.00/mg). Body Pharm's case is quality assurance: a full, published HPLC Certificate of Analysis for every batch (98.75–99.3% purity, plus sterility and endotoxin testing) where Synedica publishes none, and a dose-validated 2/4/8 mg pen. Choose Synedica for the lowest price; choose Body Pharm if verifiable, documented purity is worth a small premium.
