Milo's was nice enough to give me the basics on insulin when I was 17 (20+ yrs ago) because I was already on a cycle and I'd already bought my insulin and was gonna figure it out one way or another. At the time I'd worked up to 45-60iu/day (within 6months or so??) and people were shitting themselves saying I was gonna die, or go into a coma, or make myself diabetic.
Obviously it doesn't work that way. (I did have 1 fuckup when a post workout 12(or14?) Iu shot of humulin R wasn't even close to kicking in by the time I got home and I wanted to eat and go to bed, and with a few Ripped Fuel caps still in me from the workout I had no appetite. I always liked to do a semi-big shot before bed and eat 4-8 eggos, covered in cinnamon and sugar, butter, and syrup, and wash'em back with 1/3gal milk. I'd sleep like a baby and wake up a good 4-5lbs heavier, full, and covered in veins.... So I did another shot, I forget how much. Maybe 8-10iu thinking my insulin had gotten too warm and was "dead". 20mins later, still nothing. So I did 2-3iu IV, which should've kicked in within a few mins. Nothing. So, 3-4iu IV more and went down to cook up 2 boxes of Mac n cheese.
Got on the computer while the noodles cooked and as I was typing I noticed my hand wouldn't stop twitching. I couldn't type and kept hitting the button on the mouse on accident... This went on for a while, as I was pouring sweat and in full-on hypo (which was always the goal, I'd wait till I was in hypo, 30-35mins post IM insulin inj to eat and I could eat 3-4x what I normally would, and quick)... Then I realized ALL the water had burned out of the noodles and the noodles were burned black in the pan. Uh-oh. Made back to back to back pieces of cinnamon toast and drank a Coke and a 1/4gal milk and I was fine within 5mins.
That was the closest I'd come to "fucking up" my dose, and that was with about 22-24iu IM and another 6-7iu IV all within about 35-45mins.
I'm not at all surprised that many guys don't use or don't know how to use, or don't care for insulin, as back 20yrs ago I knew NPC and IFBB guys who had no idea how to use it or didn't care for it. I don't really care for it now ND wouldn't bother with it unless I was using GH or GHRP. Guys these days (who do use it) can also use a lot more because they're using a lot more GH than guys used back then. More GH= higher blood sugar and a higher requirement for insulin.
Everybody jumping on Milo's for whatever, but at least Milo's has used himself as a guinea pig first before advising anyone else to do it.
