I did carry Enerjel with me to the golf course and had several golfers with sore knees and elbows to try it. They all have good remarks about it helping with the pain.
that is why I have been posting for over 6 months about my sell-thru concerns. frankly, I'm just glad we are still available at gnc, although my local one in st. louis, (brentwood store), said she wasn't going to carry it anymore ... "not one customer ever asked about it"
