Bottom line
Panda Peptides earns the highest score under our methodology thanks to thorough per-size testing, low prices and generous free shipping. The main caveat is naming: its product is sold as “Triple Receptor Agonist” (SKU PP-TRA) and the page does not identify it as retatrutide.
Products and pricing
Seven sizes (5–50 mg). The product page shows a price range of $35.99–$174.99 with a 10% off badge, rather than per-size prices.

Endotoxin was below 1 EU/vial on the 20, 30 and 50 mg reports, with heavy metals not detected and sterility passed.
