no reason they cant be used together, as long as you follow the guidelines for using humalog...personally I find humalog, and even humalin r useless for growth for me

do you think insulin isnt that powerful for growth? or it just depends on the person...
and does 4iu-8iu every morning sound like a good dosage?
4 weeks on, 4 weeks off?

Ill give it to you straight. Insulin has a lot of potential, if used at doses that would scare you to look at. 4-8iu aint gonna do shit. On paper it looks great but give it a try, the vast majority of people Ive talked to say the same. I did log at 12iu a few cycles and didnt notice anything. Ive talked to a few people about this.

Depends on insulin sensitivity, your size and weight already and your expectations. It is GREAT at replenishing tapped glycogen stores way better than you could expect to do with dextrose alone (natural slin spike). If that is why you are using it, well then your expectations will mesh with the results. Bottom line, if you arent pretty damn large and finding it terribly hard to gain more size as is, you probably dont need it with all the other things that can be done.

well im not a bodybuilder, im a competive athlete, and talking to some people in my sport this has been very effective for them on more than one level.....for personal reasons and drug testing reasons im tryng non-steroidal drugs....
HGH, Slin, EPO, Clen, albuterol, B-12, ephedra ect....
