Sometimes you don’t realize how well something is working until you stop taking it. I accidentally ran out of Helios a week ago and figured I’d wait until the next BOGO to restock. Well… a couple days later all my little nagging injuries has showed back up especially my lower back. Now looking back, I didn’t realize how good I felt until this past week. Also I was not taking it for athletic performance but my last two 4 mile runs where not good. When I run I’m trying to finish as fast as possible so I always map my run. I was getting close to being under a 7 minute mile average for 4 miles but my last two I really struggled with my HR getting too high. I usually don’t do these type of threads but my personal experience with this has been outstanding.
