I tried a bottle of cracked wall capsules (I think Barlowe’s) 5 or so years ago and definitely experienced some benefits, though I can’t remember them all.
I do recall this though, my arms were definitely more pumped (24/7) - as in some notable muscle enhancement. I also recall having a somewhat mildish allergic type response in the form of areas of red skin, but I can’t remember if those areas itched though. I can’t recall any other affects it may have had on libido, energy, or wellbeing etc.
It’s odd because I usually remember everything about every supplement I have tried. Needless to say, I have been interested to try it out again myself while being tuned in to any allergy symptoms. Apparently it’s a rather common side effect.
Bottom line, I think it’s worth a try...and it’s cheap!
