at the moment I am running 10iu PWO, I started at 5iu and then went to 10iu, I'm at my 24th day and gonna run it for 40 days on and 40 days off, if you are new with slin I would recommend you start at 2iu and every 4th day up it another 2iu till you get to about 10iu, you can go higher if you wish but you must adjust your carbs/diet accordingly so you dont fall into hypo, from my research Ive always read that 10-12iu is where you should go to, but everyone is different and you need to find the "sweet spot" that works best for you. my next slin cycle I will be running slin 2X day, 10iu @noon and 10iu PWO, I cant wait to see what results I get from that, if that goes well I will switch my fast acting slin (Humalog) to a longer acting slin (not sure what brand yet).
Also I am debating if I should run it ED and not just PWO, if so I will pin 10iu before a high carb meal which will be about 5-6pm on my days off, I will post this change in my "workout log",

Whats fun about slin is that you can pack on 10lbs in 4-6 days and be more ripped then you were...just as Rich Piana said in his vid, to do this you would carb deplete for 4-5 days drinking little water as possible (take diuretics if needed), after you are deplete you will start slin and carb load all day for the next several days this way all carbs will be forced into the muscles your muscles will be super full and big, you will not get fat or bloated as you were depleted when you started so you will not spill over , during this time you will see your weight climb daily and each hour that goes by you will look bigger and bigger and pumps in the gym will be insane. Works great if your getting ready to look good for a get-together or some kind of party, just get the timing right. I have done this but only depleted for 2 days cause of some set backs during that day, but it worked wonders and I packed on several pounds without being all bloated during this short time period.
