Great experience as always!

Janoshik is the best for quick and easy testing. Recently upgraded their site and looks amazing! Makes it very easy to order and results come back for quickly. I got my results after only 3 days of them having my sample. Results come back clean and come with image of the sample. 5/5 recommend to anyone looking to test.

Those COAs mean nothing

Those COAs mean nothing. no indication how it was tested, what method was used, or even what they tested. It only says something like 98% and what is that? Assay? or what? On a dry basis or how? Is it HPLC? is it NMR? or old fashioned titration? what is the rest 2%? no indication of qualitative analysis either. they just measure something, somehow. How is it different from COA supplies by the manufacturer?

Rapid, quality testing

The reliability and range of tests on offer at Janoshik are second to none in the industry. While not cheap, they are among the most respected analytical testing laboratories and the results came back quickly after my samples arrived. They would be 5-star if the ordering process was self-service.

Gold standard in Testing Peptides

They do not sell peptides, they test them. Their customer service is great & they are truly the Gold Standard in Testing Research Peptides. Idk why the low reviews other than someone prob got mad their product got a bad testing result, which is their fault, not the testing companies fault! This company is legit, has great customer service & doesn’t let these companies who are selling BS push them around! They do honest testing! That’s what the entire peptide world needs & wants besides crooks trying to sell BS instead of doing the right thing & selling 98-99% pure research peps! Ignore the negativity! Keep up the good work Janoshik!

Not an accredited testing laboratory.

They are not an accredited testing laboratory and conform to no basic standards (ISO/IEC 17025 or similar).
Certificate of analysis doesn't even list what tests were performed and the raw data (if it even exists) is behind a paywall.
The testing is not comprehensive, since they will not use mass-spec, LC-MS, 1H-NMN to identify the compound. So it's not blind testing and you'll have to tell them what it is. Purity is based on a single HPLC run. The compound and contaminants are unknown. In real quality control departments this would never be acceptable.

Gold standard for a reason!

Gold standard for a reason!

Very easy and pleasant experience with Janoshik. They were very responsive to all emails, and always courteous and helpful in their correspondence. Turnaround, from drop-off to results, was fast, about 8 days! Highly recommend and will be using them again.

Scammers

After all these years of testing of bogus testing, as we all suspected, they were actually selling, wonder if they will third party test their own products!

Total scam company located in a car park apparently!
