Current market data
A current summary of public listings after the price comparison above. Shipping and tax are not included.
The lowest current 10mg cost for GLP-3R is $22.50 from Lost Coast Aminos. The median across vendors is $63.74.
PeptidePrices found 683 in-stock listings from 197 vendors, checked through Oct 10, 2026. The lowest 10mg cost is 65% below the vendor median of $63.74; 98 vendors (50%) fall below that median. 194 of 197 vendors (98%) publish public COA evidence.
A public COA link shows that a vendor publishes testing data. It does not prove that every listed vial has a matching current report. Match the product, strength, batch, and lot before relying on a report.
The headline and median use each vendor's lowest whole-package checkout cost to obtain at least 10mg. Smaller packages are multiplied until the target is met, while larger packages retain their full checkout price. The lowest package total is shown only as secondary context because package sizes differ. Known public coupon discounts are applied. Shipping, tax, and unverified promotions are excluded.
Price, vendor & COA
These answers use the live price, vendor, and certificate data on this page.
PeptidePrices currently compares 197 tracked vendors. The lowest tracked package total is $19.49 at Modern Research Peptides, checked October 10, 2026. The lowest comparable 10mg price is $22.50 at Lost Coast Aminos. Shipping and tax are not included. Prices are snapshots and can change.
See the vendor comparison →Modern Research Peptides has the lowest tracked package total at $19.49 as checked October 10, 2026. Shipping and tax are not included. That does not necessarily make it the lowest 10mg price or the best vendor; compare package size, quality evidence, COA coverage, fees, and the listing date.
Compare current listings →There is no defensible single “best” vendor from price alone. Compare the 197 tracked vendors in the table by total cost, standardized buy-in, independent quality rating, batch-linked COA evidence, shipping, payment options, and check date. Affiliate status does not determine the quality score.
Review the vendor evidence →PeptidePrices does not sell GLP-3R. It compares public research-vendor listings in the table below. A listing is not a medical recommendation; products labeled for research are not for human use, and regulated prescription products should come through a licensed clinician and pharmacy.
Compare public listings →Match the COA to the exact product, strength, batch or lot, and test date. Check the named laboratory, identity method, purity method, and measured content; look for sterility and endotoxin results when relevant. A purity percentage alone does not prove identity, vial content, sterility, efficacy, or safe human use.
Open the COA checklist →Research products are not for human use. Looking for clinician-supervised care instead? GLP-3R is investigational; compare currently available clinician-guided GLP-1 options.
Compare supervised options →Related pages
