Weighted factor result: 7.7/10. The published score follows the weighted result after rounding.
Evidence summary
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.
What we reviewed, with the limits of that evidence kept explicit.
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.
