Very reliable company. Each bottle has a test number associated with the batch and a QR code for the results. All batches are checked to ensure they actually contain what they say and also for endotoxins. Their shipping department will get the package out almost always by the next business day. I’ve ordered 3 times with them and spend a bit over $1,000 total and I wouldn’t do that unless I strongly trusted them. I had an issue with one of my orders and their support team responded within 10 minutes. My issue was quickly resolved by an actual person within 10 minutes, that’s rare for ANY company nowadays.
