Price methodology

A comparable listing must match: compound identity (name and, where known, CAS), milligram amount, and research-use listing. We do not compare our 30 mg to someone else’s 10 mg. We do not compare a vial to a pen.

Competitor figures on this site are advertised UK research prices taken from a live product or catalogue URL and dated. The current sheet (reviewed 2026-09-22) includes Solent Peptides (llms.txt 2026-09-19), Red Panda Peptides, Simply Peptides, Index Peptides and PeptiLab UK. We do not invent a price we have not fetched.

For each overlapping aliquot, EVOLV is merchandised at one penny under the lowest dated listing we hold. If a SKU is not cheaper than that floor, we do not say it is. We do not claim to have crawled every UK shop.

EVOLV ships lyophilised powder. Some peers describe pre-mixed as standard. The compare column is a price comparison on the matched aliquot, not a claim that reconstitution state is identical.

Shipping is noted, not ignored. EVOLV UK tracked shipping is free over £20.

Catalogue price changes update the product title, product schema, prices table, compare table and llms.txt from the same live list.
