geardepot's T.E. 400mg/ml is very good. in the past high mg/ml DVD's hurt my eyes to watch, geardepots is easy on the eyes. don't know what other sponsors carry higher Mg/ml dvd's so just giving my opinion on the one i do know as i have two good bro's watching their T.E. DVD right now.A 400mg test can be painless if made properly. As far as the DKT400, me personally would not touch it, there are plenty of other sponsors on here that carry a 400mg version test or even higher that i would feel more comfortable using.
What I do not understand is why even consider something so concentrated unless youre taking over 2 grams per week? If youre on 1g total aas per week thats still only 8ml per week if its 250mg/wk. The volume you have to inject is not high and would only require 3 injections total for the week.
Why risk all that pain just so you have less volume to inject? It makes no sense to me. Unless youre on 3g plus per week I would not even consider it, or maybe if youre doing short esters with it that are really low concentration that require more volume.
I think one secret to its painlessness is that fact that is has tested underdosed - pretty significantly.
actually a 20% bb will allow for painless solution. i personally prefer the 400/cc cause if i take 800 a week that means i could either take 1cc twice a week or 2cc once, i don't like to high a volume of oil! by the way if you use 20% bb you only need 2% ba and it will be smooth and painless! if any body cares to know i brew tren a at 200mgs/cc and it's always tolerable.
