Why QSC
Cheap is expensive when it never arrives
Very low prices usually mean something is missing: no real facility, no report you can verify, sometimes no parcel. We built the alternative, and you can check every claim yourself.
| Check |     | Very-low-price sellers |
|---|---|---|
| Orders | DHL, UPS or FedEx tracking, emailed on dispatch | Some take payment and never ship |
| Production | Professional ISO Class 7 cleanroom workshop | Some are makeshift home labs |
| Test reports | Published on Janoshik's own site, verifiable by key | Some reuse or edit other customers' reports |
| Purity | 99.5–99.98% HPLC in published Janoshik reports | Often a claim with no report you can check |
| Duties | DDP: duties and taxes paid by us | Some leave customs fees to you |
| Your own test | Test any batch; fee returned as account credit | Rarely offered |
Checkable test reports. Every Janoshik report links to Janoshik's own verification page. Enter the key and see for yourself.

Common questions
The most-asked questions before a first order.
What's the actual shipping time from China?
+
About 10–15 days door to door. Customs clearance (DDP) is included; we cover any duties.
Is every batch verified by an independent third-party lab?
+
No. Independent Janoshik reports are published for selected samples — retatrutide, tirzepatide, semaglutide and BPC-157 purity, plus endotoxin — on our Janoshik reports page, and we plan to extend Janoshik testing to most of the range and publish each report there. Batch COAs (HPLC purity and LC-MS identity) are listed in our COA library by batch ID. You can also have any batch tested yourself.
Can I pay by credit card?
+
Not at the moment. Card payments are temporarily unavailable. "Pay with crypto" at checkout takes a direct payment from your own wallet (USDT or USDC recommended; Bitcoin, Ethereum and more also work) and is 15% off. Wire transfer, PayPal, and Revolut can be arranged by email before you order, at the regular price without the 15% discount. ACH is temporarily paused. Full payment-method details on the shipping & payment page.
When will I get shipping and tracking info after I order?
+
Orders placed before 4pm (China time) typically ship by 11am the next business day. You'll get an email with the tracking number as soon as the courier — DHL, UPS, or FedEx — scans it.
Can you do private label / white-label packaging?
+
Yes — neutral or your-branded vials and boxes, starting at 100 kits (10 vials/kit) per SKU. Labeling happens during production, so it requires your artwork and a proof-approval round before the first run. Full tiers on the wholesale page.
Can I get independent third-party testing done myself?
+
Yes. Test a batch at Janoshik.com or any lab and send us the report: we return the test fee as account credit.
