What is Offline Peptides's overall rating?

Offline Peptides is rated 4.8 out of 5 on Trustpilot. Ratings change as new reviews arrive, so open the source for the live figure.

Where do the Offline Peptides reviews come from?

They are drawn from Trustpilot, summarised and linked to their source. PepLookup does not write, edit or verify reviews, and does not sell Offline Peptides's products.

Does a good rating mean Offline Peptides's products are lab-verified?

No. A review rating describes customer experience, not product testing. Check Offline Peptides's lab reports and the certificates of analysis linked from its listings, and remember a certificate describes one batch.

Can I buy from Offline Peptides through PepLookup?

No. PepLookup is a comparison tool. Orders are placed on Offline Peptides's own site, under its terms, and some links to it are affiliate links, which never change the price you pay or the rating shown.
