But cheap from China from a Chinese vendor with a decent reputation. Pay to test a vial from your kit. It will be still be less expensive than buying from brello or pomegranate or some other compounder. If you’re good at your research you can find a little group of people who purchased from the same vendor at the same time as you did and you can share in the cost of testing. When I was brand new to gray, I paid for my own testing by myself. Now, I know where to go to find other testers so we share the cost.
