Curated compounds. Undercut prices. Every batch documented.

A tight, high-signal catalog — priced below the US market, tested by an independent lab, and organized by research category. Per-mg cost shown on every vial so you never do the math in your head.

The whole vertical is built on a Canva PDF with a lab logo pasted on. Ours open on Janoshik's own database — a link a stranger can check without asking. That's the difference.

01

Scan the vial

Each vial carries a QR to its batch record. No app, no account.

02

Match the batch code

The code on the cap matches the code on the report. Line them up.

03

Open it on Janoshik

The report lives on the lab's database, not our server. If we vanished, the proof wouldn't.

Research Categories

Organized the way the bench thinks.

Supplied to qualified researchers by mechanism and target — not by outcome. Categorizations describe research context and do not imply any therapeutic result.

Metabolic Research

Receptor signaling

GLP-1, GIP and glucagon receptor agonists and amylin analogs — supplied for in vitro and preclinical study of energy-homeostasis and adipogenesis pathways.

Tissue Research

Matrix & repair models

Peptides studied in fibroblast migration, angiogenesis and extracellular-matrix models. Supplied strictly for laboratory research use.

Longevity Research

Cellular energetics

Coenzyme and copper-tripeptide compounds used in mitochondrial-function and collagen-synthesis assays. Not for human or animal use.

From the bench

The researchers who check the math.

★★★★★

"Ran my own HPLC on the retatrutide lot. Matched their published COA to the decimal. First vendor I've tested where the number was real."

★★★★☆

"A vial cracked in transit. Reshipped the next day, no argument, no photos demanded. That's the whole reason I re-order here."

— Verified buyer · CA
★★★★★

"The only shop whose Janoshik links actually open to a live report instead of a PDF they emailed themselves. That's the entire game."

Before you order

Straight answers.

Are these for human use? +

No. Every compound on this site is supplied strictly For Research Use Only, for in vitro and preclinical laboratory research by qualified researchers. Nothing here is intended for human or animal consumption, and we make no therapeutic or dosing claims.

How do I know the purity is real? +

Every batch is independently tested by Janoshik Analytical, and the report lives on the lab's own database — not a PDF we host. Scan the vial's QR, match the batch code, and open the live report yourself. If our identity or purity number doesn't match, that's a free reship.

Where does it ship from? +

US-domestic dispatch — no international customs, no multi-week wait, no mystery-origin powder. Orders confirm by email with tracking and the matching batch record.

Why are you cheaper than everyone else? +

A tight, curated catalog and a direct supply line. We show the per-mg cost on every vial so you can check us against the market — we're built to undercut it, not to hide behind volume tiers.

What if a batch fails testing? +

It doesn't ship. When a lot is under final review it's marked "held" on the lab page above — sale paused until the report clears. You're only ever buying a batch we'd verify ourselves.
