thats not a lot of B.A. to disolve and little oil for injects. I don't know why you would want a concentration 150mg (painful from BA and low oil).
I would at the least pay a few buck more get a 4g kit and use 300 pellets at most and have over 100mg 50cc's.
I wonder why you would want to make so strong bro per cc its not really any benafit just more pain from BA content.
4 g is intended for 200 pellets 75mg per cc and less painful, I imigine it can be done to make so strong with only problem maybe not enough BA to disolve pellets.
IMO pay a few buck more and do it right!
