Honest review
Checking out is as easy as it can get, fastest shipping I’ve seen, and best prices I’ve seen - on the tirzepatide at least, by a large margin

Thank you, I’m very happy you’re enjoying the experience!
For research It is very hard to find somebody that does full scale verifiable testing and reports their failed batches, which should happen quite often during a year. When vendors never fail batches, it's very suspicious. Also, sending one vial in a huge group buy does not mean testing. This guy spends most of his money on testing and you can verify on the site. It is nice to see and very refreshing that he's not trying to gouge people but make a fair living, charge a fair price, and verify testing to the nth degree. On these research compounds.

You’re very welcome, thank you for your review!
Fastest shipping I have experienced in a while. Actually left out a couple of things, but sent them out with a couple things to make up for the inconvenience quickly as well. Will definitely buy from them again.

Thank you! It happens sometimes but I will always get you right for it, I have made some improvements to my packing list to minimize these occurrences
Second order I've made with them and they're always extremely fast. Will continue to order from them. Maybe even kits
