Do you use it year round or only with other anabolics?
Secondly, i've allways heard that using slin pre-workout is risky, unless you drink carbs during the workout and immeadietly after it.
Yes, I use it year round, but only before my workout. I was taught by a pro - I would have never tried to learn on my own. There are too many variables and ways to screw up.
So far, I have never had a problem with going hypo, but in the beginning I used a blood glucose meter religiously during the whole process - for quite a while - until I learned how my body reacts.
I get up in the morning and take my shot, and then drink a carb/amino/ect shake over the next 30 minutes while getting ready for the gym. Then during my workout I have similar shake. Immediately after working out, I have a PWO shake and then a solid meal about 45m-1hr later. Then, the rest of the day I only eat meat, fibrous veggies (brocc/cauli/etc) and EFAs. Total calories = about 4,000 per day.
You definitely need to start with TOO MANY carbs in each shake and VERY gradually bring up the insulin level from about 5 IU until you get used to it and see how you react. When I finally got up to 20 IU I still had my carbs higher than needed on purpose. I then gradually reduced them until they were in the acceptable range. The whole acclimation process took about two months.
