So basically novolin R injected im instead of sub q has about the same timing as humalog ,or novalog correct ? humalog sub q kicks in about 15 minutes, peaks at around 1 hour and clears the system in about 4 hours , that was basically the root of my post and question , I don’t have easy access to humalog or novalog , but I can get novolin r otc anytime I want , I take it drafty c you’ve tried novolin or humulin R pretty much the same thing IM ? You said you have to be ready because it kicks in about 15 minutes, well that’s identical to humalog then correct? Sure you have to be ready for the kick in time , but the peak time is where you really need to be paying attention because it’s at full power at the peak , which if it’s that fast it should peak about same time , 1 hour , if that’s true thats very good news for me , we can basically change are R type insulins with the fastest acting insulins by just changing injection method , I got the perfect type of needles for insulin IM injections to , 27 gauge 1 inch and 27 gauge 5/8 inch for delts and smaller muscle groups, using 1cc luer lock syringes , just be careful guys ,those 1cc syringes sometimes throws guys off because they are use to insulin syringes, you wouldn’t think it would be that difficult adjustment, but for some it’s confusing I guess
