Don't feel anything from insulin Humilin r

[lifting214]

I do 10 iu pre workout load up on 150-200 fast acting carbs and feel nothing when working out. I work out right after. Where are these insane pumps I heard about?

So far I like igf way better I thought insulin was the Mack daddy of building muscle/ getting pumps?

I'm doing oral tren and test prop npp with insulin

Igf works well on its own I'm baffled why I don't feel anything with this slin?

First time taking slin.
