Flex Reviews

4.4 Rating 128 Reviews
Performance lab flex supplement is probably the best supplement I take. I like to work out at the gym but I end up with sore joints and muscles a lot of times. Ever since starting flex I haven't had any sore muscles or joints at all. And I noticed this after about 2 to 3 weeks.

Sounds like you've really been feeling the benefits, Michael. This is great to hear! Thank you for the positive review.
I've only started on my first bottle, and it seems to working okay. I'm not sold on it yet.

We're delighted to hear that you're feeling the benefits of Performance Lab® Flex, Victoria. Continued use will improve results too!
I have only been taking Flex for one month and I have noticed no improvement in my problems yet. I think it is too soon to expect any major changes in my condition, based on the chronicity and number of times I've been injured and how severe my injuries have been.

I have had two major accidental falls on my spine which caused degeneration of my lower and mid spine, the condition actually cripples me at times, have to literally ask for help and use crutches to get around. I ended up in one of the accidents cracking my shoulder blade in a wishbone injury. Have had problems for so long with pain like I’m going to break in half. I must say taking these supplements has helped a lot. I remember the 2nd day I took them i actually felt something happening in between the bones in my body, which was extremely bizarre it was like I could actually feel cartilage growing in my joints. Great supplements even my elderly neighbour tried some as her knees and back were aching and literally the next day she was ok....

Finished my first bottle . Seems to be working good. However, does not quite feel it is working as well as when I first started it. ordered another bottle... will see what happens.

Tried various supplements from local health food stores. Saw the TV ads about another product. Did some research and decided on Flex instead for my better half. Wow! After a couple of weeks there was such a huge difference in the reduction of pain for her. I'm generally skeptical about product claims but this stuff really works!

I will be making regular purchases of Flex, if works well.
