Why we exist

Research peptides have a trust problem.

Everyone in this category claims 99% purity. Almost nobody shows you the report. So here is ours — the most recent batch we hold a purity figure for, and the key that checks it against the laboratory’s own record.

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
Progression Labs

The new standard

Here’s the certificate. Verify it yourself.

Inside every order

From synthesis to your bench, step by step.

Five points where a peptide supplier can quietly cut a corner. Here is what happens at each of them.

  1. 01

    Synthesized in the United States

    Made and fulfilled domestically, start to finish. No overseas transshipment, no customs gamble, no mystery middlemen between the synthesis and the vial.

  2. 02

    Tested by an independent laboratory

    Samples go out to Janoshik Analytical for HPLC purity and content testing. We publish what comes back, including the lowest figure it returns.

  3. 03

    Lyophilized and sealed

    Dried under controlled conditions, then sealed in a tamper-evident vial and packed for cold transit.

  4. 04

    Shipped cold, tracked door to door

    Orders placed before 2 PM CT leave the facility the same business day, insulated and temperature-controlled, with signature required on delivery.

  5. 05

    Checkable on the product page

    Where a compound has a certificate, it is published on its product page with the laboratory's verification key — and that key authenticates with the laboratory that issued it, not with us.

Quality Protocol

What a certificate actually reports.

We don't grade our own vials. Six analytical checks performed at an independent third-party laboratory, plus the one that makes them worth trusting — each reported where the certificate covers it.

  1. 01

    Purity

    HPLC quantification — the headline percentage on the certificate.

  2. 02

    Content Verification

    Labeled mass measured in milligrams and reported on the certificate.

  3. 03

    Compound Named on the Report

    The certificate names the compound the laboratory tested, alongside its content figure.

  4. 04

    Blend Composition

    Multi-compound vials reported per component, each with its own amount.

  5. 05

    Heavy Metals Screening

    Arsenic, cadmium, lead and mercury, where the certificate reports the screen — returned: not detected.

  6. 06

    Endotoxin Testing

    Bacterial endotoxin in EU/vial, where the certificate reports it.

  7. 07

    Certificate Authentication

    Every report carries the lab's task number and key — verify it on their site, not ours.

Authenticate any certificate with the lab

Number 07 is the one a list can't fake — verification happens with the issuing laboratory, not on our site.

Common questions

What researchers ask before ordering.

Can’t find what you need? Get in touch.

Are you really US-based?

Yes. Our compounds are synthesized and fulfilled entirely within the United States — there's no overseas transshipment and nothing clearing customs to reach you.

How do you verify purity?

Purity and content are tested by HPLC at Janoshik Analytical, an independent laboratory. Where a certificate of analysis has been issued, it is published on that compound's product page along with the lab's verification key, so you can check the report against the laboratory's own record rather than ours.

What comes with my order?

Sealed, tamper-evident vials, tracked shipping, and insulated packaging that protects the cold chain from our facility to your bench. Certificates of analysis are published on the product pages, not printed in the box.

How fast do orders ship?

Orders placed before 2 PM CT ship the same business day from our US facility. Everything after that goes out the next business day, fully tracked.

Which compounds do you carry?

Research-grade compounds across peptides, blends, SARMs, and metabolic categories, each with full specifications. Where a compound has a certificate of analysis, it is published on its product page.

Are these products for human use?

No. All products are sold strictly for in-vitro laboratory research by qualified professionals. They are not drugs, supplements, or medical devices, and are not for human or animal consumption.
