Just throw it in on top then. Im not very familiar with MAG-10.
I believe it was a stack of 4-AD and 1-AD or some variation of those compounds.
Bill Roberts would have to comment, my understanding of MAG-10 is limited.
I dont think I would consider running it by itself, and I dont think its equal to say, dbol for use in a test cycle.
I would run the MAG-10 on cycle after I finished my dbol kickstart.
Or just sell it and buy more test, people pay rediculous prices for old school PH's these days, who knows why. Nostalgia I guess.
