Sources & Suppliers
Where to actually get these compounds — and, more importantly, how to know what you're getting is real, correctly dosed, and free of contaminants.
This section is about sourcing, treated with the same honesty as the rest of the site. The market — especially for peptides — is flooded with vendors, and a slick website tells you nothing. A vial can be the wrong molecule, a fraction of the labelled dose, or contaminated with heavy metals, bacterial endotoxin, or synthesis residues. The pages here rank sources by verifiable quality, not price or marketing.
Not medical advice
These are research chemicals, grey-market imports, and prescription medicines. Nothing here is a recommendation to consume anything. It is a map of what exists and how to verify it. Get bloodwork and a clinician before any protocol.
The trust taxonomy
Every supplier in this section (and in the underlying suppliers.json database) is tagged:
- 🟢 Legit — licensed/regulated pharmacy, or a research vendor with published, independently-verifiable batch testing.
- 🟡 Grey — real product, unregulated channel. Quality depends entirely on the batch CoA. Legal grey zone for import.
- 🔴 Scam / avoid — fake, hijacked, impersonation, or no verifiable testing. Documented so it can be recognised.
How to verify a peptide source (read before buying anything)
"Third-party tested" printed on a homepage is worthless on its own. What matters is a batch-specific Certificate of Analysis (CoA) you can actually inspect and independently confirm.
1. The CoA must name an independent lab
In this market that effectively means Janoshik Analytical (Czech Republic) or ACS Laboratory (US). If no lab is named, treat the product as untested.
2. The CoA must be batch-matched
The lot/batch number on the certificate must match the number on the vial you receive. A generic CoA for "a" batch ≠ your batch.
3. The CoA must cover the right tests
| Test | Method | Answers |
|---|---|---|
| Purity | HPLC | Is it ≥98–99% peptide, or cut? |
| Identity | LC-MS / mass spec | Is it actually the right molecule? |
| Endotoxin | LAL / LPS | Safe to inject? (bacterial pyrogens) |
| Sterility | microbial | Safe to inject? (contamination) |
| Heavy metals | ICP-MS (ppb) | Arsenic, cadmium, lead, mercury? |
Most vendor CoAs stop at purity + identity (+ sometimes endotoxin). Heavy-metal (ICP-MS) panels are rare — which is exactly why they matter, and why self-testing exists.
4. Verify independently — don't just trust the PDF
Janoshik publishes a public test portal → public.janoshik.com. You can look up whether a report is genuine rather than taking a vendor's screenshot on faith.
5. The gold standard: test it yourself
For total certainty of both identity and contamination, send a sample to Janoshik or ACS yourself — roughly $40–60 for HPLC + LC-MS (real compound? right amount?), plus an ICP-MS panel if you want the heavy-metal answer. For anything you'll cycle for months, testing one vial per new vendor is cheap insurance and the only thing that fully closes the loop.
Peptide formats (what you're actually buying)
| Format | What it is | Use | Verification |
|---|---|---|---|
| Lyophilised vial | Freeze-dried sterile powder in a sealed vial; you reconstitute with bacteriostatic water | Subcutaneous injection (insulin needle) — or, for short bioregulator peptides, sublingual/intranasal | ✅ Best — injectables force sterility + endotoxin testing, so reputable vial vendors publish the fullest CoAs |
| Oral capsule (synthetic) | Peptide + filler (often rice flour) in a capsule | Swallow | ⚠️ Lighter docs; filler can carry heavy metals; CoA usually "on request" |
| "Original Russian" bioregulator | Khavinson/Cytogen natural peptide complex capsules | Swallow | ⚠️ Authentic GMP supplement, but no HPLC / heavy-metal / endotoxin CoA — a different trust model |
Counter-intuitive but important
If you are willing to inject, you get access to the best-documented products, not the worst. Endotoxin + sterility testing is mandatory for injectables, so the vendors with the fullest published CoAs are the vial vendors.
