I had a gc/ms done by the good people at energy-control of a sample of butyr-fent that I initially suspected to be of bad quality. Turns out I had just horribly misdosed my prior batch and this stuff is quite nicely made.

I still suggest you stay away from this substance, but at least you can know that the product isn't adultered.
Awesome, thank you. Always love new info on opiates. How much did you send them for the test?
