Hey Jon, thanks for the comment. 🙂 I''ve only used the Vega Clean protein powder (Just wanted to show people other options) since I pretty much cover most nutrients with my diet and other supplements. So I don''t really need the additional nutrients. The only other protein powders I''ve taken in the past were Soy protein powder and before going vegan I used Reflex Instant Whey protein. Yah My protein intake was super low for a long time, but I''ve come to realize that I feel much better increasing my protein intake a little. So sometimes I''ll have soy milk (usually hot chocolate) and/or a protein shake. Not sure if it was related to my IGF-1 level.. maybe it was too low? I''ve never had it tested
