Isoflex is nothing more then a whey protein supplement. Carbion is nothing more then a carbohydrate powder. Aminocore is nothing more then a BCAA supplement. Muscleprime is a pre workout creatine supplement.
None are bad products but they are very over priced for what they are. You could get the exact same thing for a lot less money by purchasing generic version of each. You are paying a lot of money for the allmax brand name and all the marketing behind allmax.
When purchasing supplements the brand isn't particularly important. What matters is the ingredient list and supplement facts panel.
For a wheyprotein - you want to see nothing but that in the ingredients list. Wheyprotein, natural flavours, a natural calorie free sweetener like stevia and then maybe some salt, soy lechitin and cocoa powder. There are a lot of good products on the market. I personally use isolation from n2bm.com. A good whey isolate should be pretty much fat and carb free. Isolation has 26g protein, 1g carb, 0g fat per 30g scoop.
For a creatine supplement - get either a bulk creatine monohydrate powder or a capsulated creatine product like ancient strength from n2bm.com
For a BCAA - get a bulk BCAA powder or capsulated BCAA supplement like gear from n2bm.com
For a carbohydrate powder - get a bulk waxy maize or vitargo powder
