COA Available Batch Documented Research Grade

Eira London supplies GLP-RT as a lyophilised research peptide in 10, 20 and 30 mg vials, with an independent HPLC certificate for each strength’s batch and tracked UK delivery.

What GLP-RT is

GLP-RT is a synthetic peptide, supplied lyophilised in three vial sizes: 10 mg, 20 mg and 30 mg. It belongs to our Long-Chain Peptide Analogues range with Tesamorelin.

How each batch is documented

Each strength is tested as its own lot by an independent laboratory using HPLC. The current certificates for the 10, 20 and 30 mg batches are shown on this page: purity, lot number, labelled and measured amount, and test date. Every published GLP-RT batch, each with its PDF, is listed on the GLP-RT certificate of analysis page, and any lot can be checked in the COA lookup. How we test.

The peptide market has a trust problem. We don’t.

Independent reviews find roughly 40% of peptide sellers raise at least one major red flag — missing COAs, fabricated purity numbers, vanishing support. Here’s how we compare on the things that actually protect you.

Everything researchers ask before ordering.

What is GLP-RT?

GLP-RT is a synthetic peptide (lyophilised).

What purity is the current GLP-RT batch?

99.06% purity by third-party HPLC on lot JAN-209331, tested 30 Jul 2026. Labelled 10 mg; measured 11.02 mg. The certificate of analysis is on this page.

How fast does this ship?

Orders ship by tracked UK courier — typically 2–3 working days, with a next-day delivery option at checkout.

What's included with each vial?

How is purity verified?

Every batch is tested by an independent third-party lab using HPLC, and the batch-specific certificate of analysis reports the measured purity — we won't list a compound that falls below our threshold.

How should this be stored?

Lyophilised, store at -20°C in a dry, dark place. Once reconstituted, keep refrigerated at 2–8°C. Full storage and handling notes are listed on this page.
