When it comes to comp diets....it is always better to make things yourself. You never know what they actually "add". Though you are 14 weeks out, you will probably be alright. But if you just started, depending on your starting bodyfat, you need to get the diet on the road if you know what I mean. The last thing you want to do is mis-time your diet, then have to struggle at the last few weeks, and maybe have to give up some muscle to make the show. This is the difference between a simple cutting diet and a comp diet. The comp diet has an end game on a certain date, will not wait for you to get ready for it. Trust me, been there....learning to time things is critical.
