Peptide Scanner, London
A search box on the compare page, an email for every test request, and fixes for phones
Small changes from 12 to 15 October 2026 that make the site easier to use, on phones and when you ask for a free test.
Between 12 and 15 October 2026 we made some small changes that make the site easier to use.
The compare page now has a search box. The "Find a supplier" button in the menu opens this page. Before, it showed only a short line of text and a button back to the home page. Now you can pick a peptide and a country there, the same as on the home page.
When you ask for a free test, we now send you an email. It gives your reference, the vial you told us about and the test we plan to run. Before, the reference was only on the screen, so it was lost when you closed the page. If the first batch of 50 free tests is full, the email says that your request is on the waiting list.
The free testing form now asks for your country. The test depends on where the vial is posted from: UK vials are tested for purity by HPLC, and US vials for identity by mass spectrometry. About half of recent requests left the country out, so we had to write back and ask.
On iPhone, the supplier directory and our UK and US country guides were wider than the screen, so the phone showed them zoomed out. They now fit the screen.
Update: since 28 October 2026 free tests are for vials posted in the UK only. In late October we also found that a search started on the compare page could leave the empty search on screen. We fixed it on 29 October.
