you should be taking it every day. this is not an "NO booster" you're using. Study up on it. You are, in your own way, "pulsing" this steroid, which is supposed to the be the one that no one pulses due to its mild profile/taking far too long to even reach potency and potential. You COULD go more than six weeks, but I don't know how much longer you'd be able to/want to go. I know you wouldn't wanna upgrade to six months. hahahah. What you may be experiencing, weight gain-wise, is increased glycogen uptake. I'm not sure you are gaining muscle hardcore taking it a few times a week. Then again, I know little of these things, so I could be wrong.
I'll check back when someone smarter than US chimes in on this thing.
