Reference-grade compounds, backed by the assay.
Every lot is independently assayed by HPLC and LC-MS, then sealed and shipped cold — insulated, tracked, signature-on-delivery. Synthesized and fulfilled entirely in the United States.
Strictly for laboratory research use

Inside every order
What reference-grade actually looks like.
Every order ships in insulated, tamper-evident packaging with a batch-matched certificate of analysis — the same documented standard held from synthesis all the way to your bench.
- Sealed, tamper-evident vials
- Batch-matched certificate of analysis in every box
- Insulated, tracked cold-chain shipping
Why Progression Labs
Made for the bench, not the shelf.
The standards every serious lab should demand from a peptide supplier — and how we hold the line on each one.
Independent lab verification
01HPLC confirms purity and LC-MS confirms identity — on every lot, with a lot-matched report included in your shipment.
Batch-traceable certificates
02Each vial carries a unique lot number that maps to its own certificate of analysis, included with your order. Label to lab, fully traceable.
A 99%+ purity floor
03Lyophilized under controlled conditions and held to a 99%+ assay minimum, with cold-chain custody from synthesis to your bench.
Fast, fully tracked dispatch
04Orders placed before 2 PM CT leave our US facility the same day — insulated, sealed, and tracked door to door.
Synthesized & shipped in the US
05Every compound is made and fulfilled domestically. No overseas transshipment, no customs gamble, no mystery middlemen.
Researcher-first support
06Real people who know the catalog. Questions about a certificate or a lot are answered by email, usually within a business day.
Why we exist
Research peptides have a trust problem.
We built Progression Labs because researchers deserve a supply chain they can actually audit — not slogans and purity numbers no one can verify.
The old way
“Trust us — it’s 99% pure.”
- No independent testing
- No batch-level paperwork
- Origin you can't trace
- No temperature control in transit
The new standard
Here’s the certificate. Verify it yourself.
- HPLC + LC-MS on every batch
- A public certificate of analysis per vial
- A fully domestic US supply chain
- Insulated, temperature-controlled delivery
