COA & lab verification

COA ✓Third-party testedView Offline Peptides's COA page ↗

Offline publishes about 60 reports from Freedom Diagnostics and Krause Analytical. PeptidePrices checked BPC-157 10mg lot OP-BC10-0226, GLP-3R 20mg lot OP-RT20-0726, and GHK-Cu 100mg lot OP-CU100-0626. The BPC-157 and GLP-3R reports listed 99.145% and 99.88% purity and measured 12.46mg and 22.11mg. The GHK-Cu report listed more than 99.9% purity but measured only 13.2mg against the 100mg label. Purity does not prove vial content. The sampled reports did not include endotoxin, sterility, or heavy-metals results. Match the report to the exact lot. Affiliate status does not influence the rating.

Our verdict on Offline Peptides

Offline is transparent about many laboratory reports, but one sampled report shows a serious vial-content failure. That result is a material limit on the rating.

Check the exact lot, measured content, and report before an order. Use a reversible payment method and report a valid claim within the published seven-day window.

More about Offline Peptides

Offline Peptides is a US research supplier. It publishes a broad catalog with many vial sizes. PeptidePrices imports supported single compounds and supported blends. It excludes bacteriostatic water and mixed products that do not have a valid comparison match.

Offline publishes about 60 reports from Freedom Diagnostics and Krause Analytical. This is useful public evidence. It also exposes a material quality-control concern. The sampled GHK-Cu 100mg report for lot OP-CU100-0626 lists more than 99.9% purity but only 13.2mg of measured content. Purity and vial content are different measures. Buyers should check both values.

Trustpilot showed 4.7/5 across 57 reviews on July 28, 2026. This is a strong independent customer signal. Some recent reviews report delayed handoff, missed messages, or report-matching concerns. The sampled underfill and strict claims policy keep the total score at 7.5/10. Affiliate status does not affect the score.
