Our manifesto
The research peptide industry
has a transparency problem.
We built Ascend because researchers deserve a supply chain they can actually verify - not marketing copy and unverified purity claims.
Most suppliers
Trust us, it's 99% pure.
- No third-party testing
- No batch-level documentation
- Unknown synthesis origin
- No cold-chain handling
Ascend
The new standard
Here's the COA. Verify it yourself.
- Independent HPLC + LC-MS testing, every batch
- Public certificate of analysis per vial
- Full US domestic supply chain
- Insulated, temperature-controlled shipping
Why Ascend
Built for the lab,
not the shelf.
Six things every researcher should expect from their peptide supplier - and why we deliver on all of them.
Independent third-party testing
HPLC for purity, LC-MS for identity - every batch, every time, published on the product page.
Batch-level certificates of analysis
Every vial carries a unique batch ID linking to its public COA. Full traceability from label to lab.
99%+ minimum purity standard
Lyophilized under controlled conditions. Proper cold-chain handling from synthesis to your bench.
Next-day shipping, fully tracked
Orders before 2pm CT ship same day from our US facility. Insulated packaging and tracking included.

Common questions
Everything researchers
ask before ordering.
Can't find what you're looking for? Get in touch.
Are you actually US-domestic?
Yes - every step. Our peptides are synthesized, lyophilized, tested, stored, and shipped entirely within the United States. No international transshipment, no customs handoffs, no overseas drop-shippers. Orders ship from our US facility with full tracking.
How is purity verified?
Every batch is tested by an independent lab using HPLC for purity and LC-MS for identity. The COA is stamped with the batch number, test date, and lab name and uploaded to the product page before any vial from that lot ships.
What documentation comes with my order?
Every vial ships with a tamper-evident seal and a packing slip referencing the batch ID. The matching certificate of analysis — including HPLC purity, LC-MS identity, and endotoxin results — is available on the product page and in your account downloads.
How fast do orders ship?
Orders placed before 2 pm CT ship the same business day. Standard delivery is 2–4 business days. Free US shipping on orders over $300.
What compounds do you carry?
We stock 38+ research peptides including GLP-1 analogs, melanocortin peptides, GH secretagogues, BPC-157, TB-500, neuropeptides, and more. View the full catalog on our shop page.
Are these products for human use?
No. All products on this site are sold for laboratory research use only. They are not intended to diagnose, treat, cure, or prevent any disease, and are not for human or veterinary consumption. By purchasing you confirm you are a qualified researcher.
