I have previously used PowerBar Recovery Protein Powder. I thought I was recovering quite well until I tried Gu Roctane Protein Recovery Drink Mix. The latter had a profound effect on recovery. Though I don’t use any other Gu products, as I don’t like the taste the Gu recovery Chocolate Smoothie is an exception. Maybe my endurance increased hence the recovery was better or it was really the change of the recovery drink helped I can’t say it for sure. Best option would probably be to try various products and decide for yourself.
Hope it helps
