2026 vendor comparison
DelixLabs vs. Swiss Chems
Testing you can check yourself, shipping, catalog and price, compared side by side.
Quick verdict
Swiss Chems is a long-running vendor with a wide catalog, a low free-shipping line ($100 in the US) and lower list prices on some compounds. DelixLabs is the better fit if you want to verify every batch on the testing lab’s own website before you trust it, or if you’re researching GLP-class compounds like GLP-RT or GLP-TZ, which Swiss Chems doesn’t list as vials.

How to verify a batch yourself
Every DelixLabs batch is tested by Janoshik Analytical before it ships. We publish the Janoshik task number and verification key for each batch, so you can open the original report on janoshik.com, a site we don’t host or control. That’s 26 batches so far, with HPLC purity between 99.0% and 99.97% on the compounds tested for purity. If a key doesn’t return a report, the COA isn’t real. Apply the same test to any vendor you’re considering.

Is Swiss Chems legit?
Swiss Chems is an established vendor that has been operating for years and posts lab reports on its site. The main difference from DelixLabs is how you check those reports: we publish a Janoshik key for every batch so you can open the report on janoshik.com yourself.
Does Swiss Chems sell GLP-RT?
As of October 2026 we did not find GLP-RT or GLP-TZ vials on their site. Their only GLP-class listing was oral Orforglipron. DelixLabs carries GLP-RT 10, 20, 30 and 60 mg.
Which ships faster?
Both ship same day on weekdays if you order before the cutoff: 12 PM ET at Swiss Chems, 2 PM CT at DelixLabs.
How do I check a DelixLabs COA?
Find the task number and key for your batch on our COA page or product page, go to janoshik.com/verify and enter both. Janoshik confirms the test on its own site, not ours.
Bottom line
If the deciding factor is the lowest sticker price on a basic peptide, Swiss Chems may win. If it’s being able to prove what’s in the vial, using a report you pull from the lab yourself, or you need a GLP-class compound, start with DelixLabs. Order one vial, check the key, and decide.
