I am glad you are no longer taking Impact Nutrition products as they have been scamming people with their overpriced herbs.
Secondly, your current stack is excellent. However, should money be an issue then I suggest you re consider taking glutamine as supplementation during resistance training has no significant effect on muscle performance, body composition or muscle protein degradation in young healthy adults. Nor does the addition of glutamine stimulate muscle protein synthesis rate.
I have heard consuming large dosages of glutamine (10-40 grams) will combat its poor oral bio availability, however even the study by Candow et al (2001), where .9g of glutamine was consumed per kg had absolutely no impact on muscle performance. For a 90kg bber this amounts to 90grams of glutamine!

Stick to the basics, whey, dextrose/malto, BCAAs, multivitamins and fish oil these supplements combined with a proper diet and training program will give you fantastic results.
