Bottom line
Ion Peptide combines low prices with some of the most complete lab reports we have seen and a large Trustpilot base. The coded product name and the lack of lost-package cover are the main drawbacks.
Products and pricing
Listed as “ION-3R” with no description on the visible page. The store’s product data describes it as “ION-3R (LY-3437943) – Triple-Agonist Research Compound” acting on GLP-1, GIP and glucagon receptors, and one COA file on the page is named “Retatrutide”. Prices: 5 mg $39, 10 mg $58.50, 20 mg $99.95, 30 mg $139, 40 mg $165, 50 mg $189, 60 mg $219. The 7 mg ($49) and 100 mg ($299.95) were out of stock. The vendor offers bulk discounts of 10% (4–5 units), 16% (6–9) and 25% (10+).
Testing
COAs are posted for each size and lot. The newest 10 mg report from Freedom Diagnostics (client “Ion Research”, lot ION3R10-09022026, reported September 5, 2026) shows 99.83% HPLC purity, 11.18 mg net content, LC-MS identity confirmed, endotoxin (LAL) pass, no detectable microbial DNA, arsenic/cadmium/lead/mercury pass and no fentanyl detected. The 6, 15, 40 and 100 mg options had no report marked current.
Shipping and payment
Orders before 5 pm ET on business days usually ship the same day, but a site banner asks buyers to allow 2 extra days for processing. Free 2-day FedEx/UPS over $250; 2-day and next-day upgrades are offered at checkout. Rates below $250 are not stated. Carriers are UPS, FedEx and USPS, with tracking by email.
