First Day...

Posted by iHerb Customer on Feb 17, 2018 | Verified Purchase

I will update this when I have a full week ++ to base the review on, but the first night experience was interesting enough to start of with. Disclaimers: I still have no idea how to take this in the most ideal way. -I dont have 30-60 minutes free to "wait" at any given and I’m stacking a whole pharmacy as well as eating on a tight schedule. - I took the suggested 3 pills not too long after glutamine and approximately 30 min after eating a protein bar. Now. First I spent about 1 hour with the most intense bowel movements ever. No pain, but the amount of gass produced was just out of this world. Secondly, I’ve never had such a deep sleep ever. I could barely wake up. So sleep wise it delivers. Lastly, my muscles are sore as ****. I havent had sore muscles after working out in ages. Not sure whether that is a good or bad thing. I’ll try it for a week and see what happens, while figuring out how to be away with the gass part.
