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.

GHK-Cu (50mg)
Copper tripeptide. Lyophilized powder, 50mg per vial.
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 lot 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
The new standard
Here’s the certificate. Verify it yourself.
One of 24 published certificates. 14 report a purity figure, averaging 99.5% — the lowest 99.06%. We don’t hold or control that record.
See the full reportInside every order
From synthesis to your bench, documented at every step.
Five points where a peptide supplier can quietly cut a corner. Here is what happens at each of them.
- 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.
- 02
Assayed by an independent laboratory
Every lot goes out to Janoshik Analytical — HPLC for purity, LC-MS for identity. We publish what comes back, including the lowest figure it returns.
- 03
Sealed and stamped with its lot
Lyophilized under controlled conditions, then sealed in a tamper-evident vial carrying a unique lot number that maps to that batch's own certificate.
- 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.
- 05
Checkable once it reaches you
The certificate in the box is the one published against that lot, and its key authenticates with the laboratory that issued it — not with us.
Questions about a lot or a certificate reach someone who knows the catalog — usually answered within one business day.

Buy more, pay less per vial.
Volume pricing is built into the price, and it works per compound: two vials of one compound take 10% off that compound, ten take 25%. Every compound earns its own rate independently, and discount codes still apply on top.
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?
Every lot is independently assayed by HPLC for purity and LC-MS for identity. A lot-matched certificate of analysis is included with every shipment, and each vial's lot number maps back to it.
What comes with my order?
A lot-matched certificate of analysis, tracked shipping, and insulated, tamper-evident packaging that protects the cold chain from our facility to your bench.
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?
38+ research-grade compounds across peptides, blends, SARMs, and metabolic categories — each with full specifications and a lot-matched certificate of analysis in every shipment.
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.
