I am going to start with 4iu novolog R pre workout and go from there.
I am only looking for the muscle breakdown inhibition I would ASSUME that 4iu will do that sufficiently.
.
Did a fair bit of reading a while back and amino availability was always the bottleneck vs slin dosage (iirc most reading was on burns victims with amino infusion + slin).
Add to that @Joshua also subscribed to lower doses and higher amino's had me sold.
Not sure how it went tbh but did a good month of multi day jabs c4-6IU with lots of aminos (honestly cant remember how much but used bcaas perhaps 40g) between meals. Made decent composition changes but perhaps didnt make a huge difference as diet was tight, hard to tell.
So yeah, i would also assume that 4iu is sufficient for your purposes.
