Well my man, I take novolin R too. Along with Tren ace, test E, and DBol w/(ghrp6 and igf1-lr3). I can tell you it will be doing its job 30 min after injection But stays for 5 hrs. Start with a low dose to see how your body reacts to it like 4iu And work up to 10-12iu. Definitely just keep carbs in you and best to take 20 min before breakfast...... Like I said keep carb loading. I use it for a pre workout with carb meal myself...... GREAT pumps. There's a lil more to it but there thereby go.
