Carb Shock does not supply to my country, but I tried to mimic the Carb Shock formula the best I could.
It contains:

12 grams Malto-Dextrine
5 grams Leucine
3 grams Trehalose
475 mg Licorice Root Extract
70 mg Fenugreek Seed Extract

I did not add Pancreatin, Papain and Protease, because I have access to PeptoPro (casein hydrolysate) and whey hydrolysate
Now in regards to adding a protein source to this formula, my question is what would be my best option:

1. Use 15-25 grams of hydrolysate protein only
2. Use a combination of hydrolysate (10 grams), isolate (10 grams) and casein (10 grams)
