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
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 published against that lot is the one your vial's lot number maps to, 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.

Quality Protocol
Every lot, 8× verified.
We don't grade our own vials. Six analytical checks performed at an accredited third-party laboratory, plus the two that make them worth trusting — all tied to the lot number on the vial in your hand.
- 01
Purity
HPLC quantification against specification — the headline percentage on the certificate.
- 02
Content Verification
Labeled mass verified in milligrams — the label's claim is the vial's contents.
- 03
Identity Confirmation
The compound is confirmed to be exactly what the label says it is.
- 04
Blend Composition
Multi-compound vials reported per component, each with its own amount.
- 05
Heavy Metals Screening
Arsenic, cadmium, lead and mercury screened on covered lots — reported: not detected.
- 06
Endotoxin Testing
Bacterial endotoxin measured on covered lots, reported in EU/mg on the certificate.
- 07
Lot Traceability
The lot number on your vial is the lot number on its certificate — one lot, one report.
- 08
Certificate Authentication
Every report carries the lab's task number and key — verify it on their site, not ours.
Numbers 07 and 08 are the ones a list can't fake — verification happens with the issuing laboratory, not on our site.
Stock up & save
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 published for every lot, and each vial's lot number maps back to it.
What comes with my order?
Sealed, lot-numbered vials, tracked shipping, and insulated, tamper-evident packaging that protects the cold chain from our facility to your bench. Each lot's certificate of analysis is published online, 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?
38+ research-grade compounds across peptides, blends, SARMs, and metabolic categories — each with full specifications and a lot-matched certificate of analysis published online.
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.
