Here's what I've compiled from my own orders and reports from other members. Prices are approximate and in USD:
Individual tests:
- HPLC Purity only: $120
- HPLC Identity + Purity: $175-180
- Quantitative assay (concentration): $250
- Sterility testing (endotoxin LAL): $180-200
- Heavy metals screen: $150
- Full peptide identification (mass spec): $200
Bundles:
- Purity + Identity + Quantitative: $340-360
- Comprehensive panel (purity + identity + sterility + quantitative): $380-420
Discounts:
- Crypto payment: ~10% off
- Group submissions (3+ samples): ~15% off per sample
- Returning customer (5+ orders): sometimes offered loyalty pricing
These are ballpark figures — Janoshik adjusts pricing periodically. Always confirm on their website or via email before submitting.

Something nobody mentions: the cost of NOT testing.
I did the math on this once. Say you order $300 worth of tirzepatide from a new vendor. Without testing:
- If it's bunk: you lost $300 + wasted weeks of your protocol
- If it's contaminated: potential medical bills, infection risk
- If it's misdosed: ineffective treatment or overdose risk
With testing (~$180 for identity + purity):
- You know exactly what you have
- You protect your health
- You contribute data to the community
- You can make an informed decision about the vendor
The $180 test is literally insurance on your health. When you frame it that way, it's the cheapest part of the whole equation.

Great data compilation. Let me add some context on turnaround time variability:
Factors that affect Janoshik turnaround:
1. Season — Q4/Q1 tends to be busier (new year health goals = more peptide orders = more testing)
2. Compound complexity — simple peptides are faster than novel compounds they need to develop methods for
3. Postal delays — this is the biggest variable and completely outside anyone's control
4. Payment confirmation — bank transfers take longer to clear than crypto
Historical average turnaround (after sample receipt):
- 2024: 10-15 business days
- 2025 H1: 8-12 business days
- 2025 H2: 7-10 business days
- 2026 Q1: 5-10 business days
They've definitely been improving. Credit where it's due. 📈

Last question — is there any risk in shipping peptide samples internationally? Like, could customs seize it and then I'm in trouble?

This comes up a lot. The short answer: the risk is minimal.
- You're sending a tiny amount (under 1ml) of a research chemical for analytical testing — this is a legitimate activity
- Peptides are not scheduled/controlled substances in most jurisdictions
- The customs declaration says "laboratory reference sample" which is accurate
- Janoshik receives hundreds of international shipments monthly with very few issues
The worst case scenario is customs confiscates the sample. You're out the cost of shipping and the sample, but you won't get a knock on your door over 0.3ml of peptide solution.
That said, I'm not a lawyer, and customs rules vary by country. If you're in a country with extremely strict import controls (looking at you, Australia 🇦🇺), do your own research on the legality of sending analytical samples internationally.
Don't stress about it too much. Just label it properly and send it. 📬
