Unless you are VERY experienced with slin, I would stick with a normal bulking diet. Slin can and has been used during cutting and even right upto the day prior to a show. But the individuals that did this were very experienced and knew exactly how their body reacted to slin. But basically, slin can be used in any case where you can take in carbs. Therfore a ketogenic diet would be a BIG slin no no. But slin can be used during carb depleting diets at the times when carbs are taken in. You just have to adjust the amount of slin to the amount of carbs you are taking in. But I can't stress enough that the individuals that do this, really know how they react and can judge how much slin to use for the amont of carbs they take in. Everyone is different too so you can't say what works for one guy, will work for the next.
My advise would be to stay away from slin on carb reduced diets.
