Compare Peptides (comparepeptides.co.za) is an independent South African price-comparison site for research peptides. It tracks the live catalogue prices of South African research-peptide suppliers every day, compares them side by side on the same compound and vial size, and shows which suppliers publish lab testing. It does not sell peptides.
Compare Peptides shows, for every supplier, whether a lab test (Certificate of Analysis) is published, and flags where none is shown. A COA only proves the batch it was issued for, so always confirm the current batch's COA with the supplier before you buy.
How we rank, in six steps
The exact criteria we apply, in order.
1. Ranked by price
Lowest price first for the same compound and vial size, on every compound page.
2. Featured supplier
Our featured supplier is pinned first on the homepage and at the top of each price table, clearly labelled, and the supplier list is curated against its prices. The BEST PRICE badge always marks the genuinely cheapest row.
3. Lab testing shown
The Tested column shows whether a supplier publishes a lab test (COA). We do not test products ourselves.
4. Excluded by policy
Wholesale-only sellers and shops that mainly sell steroids, SARMs or tanning products are not listed.
5. Fresh daily
Prices & stock re-scraped every day; lab testing, payment, support and delivery details re-audited periodically.
6. Data-led
Suppliers are shown on the data: price, lab testing, payment, support and delivery. Some outbound links may be partner links.
