Humalin-R was injected and yeah I injected 70 IU had a 1cc insulin syring and filled er up to 70 mark almost all the way full. Anyhow I am fine, got a little dizzy, numb mouth, and weird vision for a couple hours. But I mean if you are going to only do 10iu or 15iu that is a breeze and no worries. I am use to using the insulin syringes for GH, so GH was 10iu per ml when the insulin is 100iu per ml. That is where I messed up. Anyhow I know now and here to share my experience.
