the OP is an insulin 'newbie' and he's running 10 iu of slin twice a day . i don't think many guys on this forum think that darkwing is in any kind of 'danger' . . . but then again we have not heard from him on this thread in two weeks, idk man maybe that 2iu of extra slin took him out . you alive darkwing brother !!?
insulin is very much person to person dependent . Really depends on your genetics, metabolism, insulin and carb sensitivity . some guys respond well and become very anabolic and can put on good lean mass with slin (bulk up beyond what they could without it , with a high calorie diet) ,, BUT other guys get fat as fuck and the results are not what they wanted at all .
some pros run it , some pros don't' . its really person dependent. you may notice nothing at all , or you may not like the results , or you may benefit and put on some of the mass you've been looking for for years and slin (along with a good AAS protocol) may be of benefit.
let us know how it works out for you !
