The combo if GH, AAS and Slin have a synergy when ran together. Depending on your dose of GH it will down regulate your natural insulin production but increase sensitivity to exogenous insulin. This is where the combo will flourish. It sure can do big things including making you fat as well as kill you
I have ran slin (humilin R) many times and always PWO. I always start at 4iu and increase till I hit 10iu. The big jump for me in terms of effects is from 6 to 8iu then 8 to 10. This is where it really starts to fill me out. Although slin is dangerous it can be ran very safely in order to minimize the negative side effects. The main thing is to read read read and once you have got a handle on it read some more. The standard is 10 grams carbs per IU for your post injection shake as well as the meals within the slin window but my last run with GH and slin I went up to 120g carbs on 10iu without gaining any fat.
I in no way condone the use of it to anyone who has not done their research, nor anyone who is not on point with their diet at all times, I also suggest anyone venturing into the territory to purchase a meter to monitor your BG levels. The safer you are the better
