Yes and No
Firstly depends on your budget
What are your goals
Don’t expect miracles from 2,3,4 iu a day without insulin. But you will notice a fullness to your muscles fat is easier to keep off, skin may change for the better etc. Don’t expect to get huge off of those doses in any short period of time. 1-2 kits isn’t going to completely change your physique or anything
Now if you want max muscle growth and cell splitting then IMO insulin and high dose androgens are necessary fuel to the fire. Insulin will help with IGF conversion.
If you start pushing 8 plus IU a day with heavy androgens slin and more food than you could imagine you start seeing some pretty dramatic results. I’ve gone as high as 15 iu a day before with TP blacks, slin, moderate test and high tren. It was incredible. I was on time off from work luckily because there is no way I could have a job and function with the lethargy I was experiencing
