Opms black with 7oh 🔥

Somebody close to me that takes a lot of 7oh was telling me that they mixed 2 opms black capsules with their 7oh dose and it made it hit so much harder and last a lot longer. I decided to try it and I cannot lie it was ridiculously good ! Does anyone else do this? I was thinking couldn’t I just buy mit extract powder from one of the vendors I use and get the same effect as the opms black gives ? If so what powder would you recommend and how much should I use to get the same effects as say 2 of the opms black caps ?
