damn dude, u have more slin questions than anyone ive ever seen. No they will not be turned into fat, unless u use the 100g carbs for 5iu of slin for a continued time period, keep it at 100g of carbs till u reach 10 ius slin, stay at that, then u can toy w/ grams of carbs per iu, on ur second slin' cycle, once u know how ur body reacts. Drink as much protien and quality carbs in that 4 hr. period (assuming it is humulin-r). Try for at least 150g of protein in that time period. take advantage of the anabolic time period.
