PERSONAL EXPERIENCE from over a dozen logs on here..
That is real world and real life evidence and support.
I can dig up more if that is not enough, let alone the feedback from people who have compared it to other products and stated it the best amino/performance product they have tried.
Since perform is only a few months onto the market, the feedback continues to grow on a daily basis. You can take it for what it is worth and what the people are stating with their honest feedback. If you wish to write it off that is totally up to you the consumer.
Again the formula's vary and are different with the ingredient make up, but since you are looking for information I thought it would be helpful given the positive vibes it has received.
For example more feedback:
"Xtend Perform continues to perform. Results are still good. Still am hitting my workouts really hard, hitting heavy weight yet I'm eating a decent amount less. I'm really impressed with this product so far. Have definitely been recommending it to everyone at the gym. Will be sad when I'm out but will definitely be picking up another bottle.
I was really fearing my cut this year because I didn't want to be sluggish at the gym or not be able to go heavy. Xtend Perform is really helping to relieve those fears.
"
"I am a pretty active guy and I have found my training has been really good. I have been in a calorie deficit for a while so any help with recovery and rest periods is a benefit. The last three weeks supplementing with Xtend Perform has taking lowered my rest period and gave me some extra energy which has maintained and also improved my training (have added some reps and a little weight). I also take this while I am playing golf every now and then. I always walk when I play and have found this has given me an extra kick to when I need it or am feeling tired."
"Xtend Peform is a great product. Helps tremendously with endurance and strength at the gym, even while on a cut. Flavoring is great. \ It is quite a bit more than other BCAA products...BUT, it offers a lot more as well."
Had a 2.5 hour upper body session last night. Started with deadlifts, then incline reverse grip press, then negative heavy incline bench, then straight arm pull downs on a bar. Then narrow grip chest press on HS, then Y rear delt pulls, incline flies, standing shoulder press, seated curls, seated overhead tricep press. My muscles gave out before my energy did. Love Perform, damn!

I want to get a little review Up in here. It has been a few days now that I have stopped using xtend perform. (bottles gone its magic)
And Right now, I really wish i had some more intra workout , it tasted so good. DEF miss tasting and drinking that every day.
SO far now that its gone I realized how good of a product it was now that I am not using it.
Nothing but solid workouts with Perform.
Scivation is really putting out some solid products with these two. I'm still pretty astonished that I could tell the difference in workout improvement while using Perform. I'm scared to ever stop using it now!
Performance- 10/10, I'd score it higher if possible. This product delivers on its claims. Increases strength/endurance/pump, decrease rest time between sets, aids in recovery (no doms, soreness), increase endurance (makes fasted cardio very easy)

this stuff simply works, been increasing weight and doing extra reps/sets on all lifts this week, very little rest time needed between sets
sipped on xtend perform throughout, made cardio session easier than usual
