Is igf-1 really

is igf-1 really worth the money? I mean I paid 1680$ for 4ml. I have read some posts and I geuss people aren't really noticing anything. Has anyone gained a good amount of size by either weighing yourself or by just looking at yourself?

I don't think you'll gain a lot of size or weight using it by itself, but I've heard of good results using it with AAS cycles.

but the size is permanet from what I hear right? Any idea what a good cycle would be with it?tren & test maybe?
