2026 vendor comparison
DelixLabs vs. Ascension Peptides
Two US vendors with the same 2 PM CT cutoff. Here is where they differ.
Quick verdict
Ascension Peptides and DelixLabs are closer than most comparisons: both are US-only and both ship same day on orders by 2 PM CT. Ascension wins on some per-vial prices and volume discounts. DelixLabs wins on independent verification (a Janoshik key for every batch) and on GLP-class compounds like GLP-RT and GLP-TZ, which Ascension doesn’t list.

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 Ascension Peptides legit?
Ascension is a US vendor that publishes COAs from two third-party labs. The difference with DelixLabs is how you check them: we give you a Janoshik task number and key so you can confirm the test on the lab’s own site.
Does Ascension sell GLP-RT?
We did not find GLP-RT or GLP-TZ on their site as of October 2026. DelixLabs carries GLP-RT 10, 20, 30 and 60 mg.
Which is cheaper?
It depends on the compound. Ascension lists TB-500 5 mg lower than we do. DelixLabs has lower shipping ($10 vs $15) and free shipping from $100, and our kits bundle vials with BAC water at a discount.
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
For BPC-157 and TB-500 on price alone, Ascension is competitive. For anything GLP-class, or when you want to confirm the batch with the lab yourself, DelixLabs is the stronger pick. Our Tissue Repair Stack (two BPC-157 + two TB-500 + BAC water) also closes most of the price gap and ships free.
