"Got to the Keyhole in record time....for me anyway. Took 2 more capsules when I got there. Made it up and down without puking.  Since I'm a low-lander this stuff helped make the trip much more enjoyable and the high elevations more tolerable."

"I've done 3 fourteeners this summer and the last one was the easiest. It's probably because I started taking this Performance Gold stuff in preparation. Good product."

"You know that trail by the alpine visitor center in RMNP? Last year I couldn't begin to make that hike. I was hoping this product would help me...and it did. Made it with ease. I'm 71 and now I'm ready to tackle Long's Peak...yeah, in my dreams!"

"Performance Gold has made everything easier, biking, kayaking, running. I'm a lot stronger. All my weights have steadily moved up in the gym. Thanks Muscle Valley for such an incredible product."

"I've been bodybuilding since I was 17 yrs old. So almost 10 years. I've taken lots of different supplements and have found some good ones. I wanted to compare Performance GOLD to a formula I take that's $20 more. For the last 4 months I've taken Gold. Not much difference at all. In fact, I might have a little more endurance with the Gold. Looks like I'll be switching and saving $20 a month."

"I have studied many of the products that have come out on the market since 2003, and none have shown to be valid, that could assist in building muscle and aiding recuperation without major potential side effects. I've been lifting weights for over
20 years now, so I have a pretty good idea when something has an impact on my training program. I started taking Performance GOLD in Dec 2021 at a body weight of 270 lbs, 16% body-fat, or 224 lbs of lean muscle. After the first month I retested; body weight 276, 13% body-fat, 241 lbs lean muscle. At the beginning of Feb, the second full month; body weight 278, 10% body-fat and 247 lbs of lean muscle.
In addition, my 1 rep max bench press jumped 17% and 1rm squat jumped 23%. I wish I could say I made major changes in my diet or sleep pattern during this time, but I didn't. I sleep 4-5 hours per night and ate pretty much whatever I wanted,  At 44 yrs of age, I am not an easy sell, but Performance GOLD has made a believer out of me. I know of no other product that, given my situation, would have benefitted me the way this product has."
