We are a manufacturer, after we start our production, we produce them at 100kg or above at a time. The manufacture process, synthesis process is same after seting well. So the whole batch product quality should be same. Until now, only one customer reported our testosterone D in bad quality. Maybe is because rare customers use this product. But we have received good feedback from our customer for other products:
Test E Janoshik report from customer, at 95% purity.

Good feedback from customer:
One thing we can sure that, all of our products will be tesing under our internal testing machines before selling. We will not sell low quality products. We will not make low quality products to ruin our reputaion we have made.
If customers didn't believe our internal testing reports, we encourage customers to do the testing by them own. Base on some conditions, we will reimburse the testing fee to customers or credict the testing fee in the order.
About the 89% purity from Janoshik, we can't say Janoshik lab is not good, they certainly a good lab, but maybe we have different, Testing Methods or calibrated instruments and reference standards are not same? Or Moisture absorption, oxidation, or contamination can lower purity as well. Too many factors. Hard to track back which party is wrong.
For customers who are worried about our products quality, you are welcome to ask for small sample to do the testing first, after you testing in high quality, you start to buy.
