I ran a slin cycle for the first time about 8 years ago. I used the shortest acting version and a very moderate dosing protocol. I had an awful time with sugar/carb/protein/creatine shakes after injection. On a few occasions I threw them up and had to redrink more on an upset stomach. I had a very scary episode that is still unexplained. About a week after stopping I was in the car with my ex and start to feel light headed and drowsy. Within minutes I was on the very of passing out... that black circle around my vision started closing in. We pulled over and got a sugary drink... which helped very little. It wasnt until I was able to have a full meal that I recovered. Still to this day no one has been able to explain why I had that episode so long after stopping a short cycle of slin. It was enough to turn me off to slin forever.

Insulin is outstanding but ridiculously dangerous. Here's how I run it. Always Humalog or Novolog as those are out of your system the fastest and are the "easiest" to manage so to speak. Start with 2iu and add 1 iu each time till you get to 10 iu's MAX. This is to make sure you don't have some crazy adverse reaction and die. Always best to ease into insulin use to see how it affects you. The timing of your meals depends solely on what kind of insulin you are using. Here's my routine when I use Novolog. The timing for Humalog is very similar so this is how I would run it with Humalog as well.

10 iu's of Novolog post workout followed by my post workout shake consisting of 25g dextrose, 75g maltodextrin, 50g whey protein isolate, 10g creatine, 10-15g glutamine.

1 hour to 1 hour and 15 minutes after injection I then eat a soid meal consisting of 50g protein and 80-100g of complex carbs like brown rice, whole wheat bread, or whole wheat pasta.

This is usually enough to get me in the clear but every now and then I'll start getting low blood sugar a few hours after my solid meal so I've gotten into the habit of eating another meal with 60-75g of carbs 2.5 hours after my solid meal (3.5 hours post injection.)

Again, my meal timing is based of using Novolog. If you use other forms of insulin the times will vary Humulin R is available at pharmacies without a prescription but it lasts longer and thus is more difficult to manage and requires different meal timing.

Some rules to follow when using insulin:

Do not EVER go anywhere or be any place without simple sugars in case you start to go hypoglycemic. NO EXCEPTIONS EVER! You can die, so don't fuck around. Always have glucose tabs, raisins, honey, soda....anything with simple sugars...on hand at all times. If you start to feel light headed slam simple carbs immediately.

Do not EVER go to sleep within 5 hours of administering insulin or you could die. If you go hypo while sleeping you may never wake up. That means if you do late evening workouts, don't use insulin, period.

Sound like fun??? It isn't. Insulin makes you feel like shit too by the way. Tired, sluggish, etc. It really does add on the mass like nothing else but is it worth the risk? If you do decide to use it you must research it heavily. Then research it some more. Then when you think you're an expert on it, research it more. This isn't something you blindly go into or even do because some guy on an internet forum told you how to do it. This is no joke. Insulin can kill you.
