Definitely agree with 'Plazma' as number one. Though:
Do you really feel that this is significantly better than taking 1 dose and purchasing some other Biotest supps?
I'm in a situation where I could afford 2 doses of Plazma per session, OR 1 dose and a few other meaningful ancillaries -- such as Flameout. Personally, I'd hate to give up my Flameout. The stuff is magic (tendonitis issues have disappeared and only reappear when I stop)
Oh, also, on that note, colenelson09 -- definitely consider some Flameout if you can afford it and Plazma. I've never used Mag-10, so can't chime in there, but have loved Flameout. While not necessarily 'for' strength and size, what it does for overall wellbeing, insulin sensitivity and nutrient repartioning will go a long way towards your strength and size.
