"Your pro mass stack is incredible, it worked great and i'm a hard gainer. Hard to believe this stuff is legal.

"Well it's been two weeks since I started the pro mass stack...and I can say I am really impressed. My strength is through the roof and the size is coming. I was a little skeptical before I started after having been burned by other countless products. I'm glad I gave these products a chance. I feel getting somewhere in the gym instead of running in place! Pumps are incredible and my endurance is ridiculous. I have enough energy to add a set or two to each of my workouts. It's been two weeks and I've already put on 7lbs. You guys are the real deal! Thanks for making a product that actually works and isn't a bunch of crap."

"I just wanted to say how much i love your products. i used the Pro Mass Stack, now my arms thicker and fuller and I added at least 40lbs to all my major lifts. I have tons more energy and I feel thicker, fuller and stronger. I have more confidence in the gym because of the great results I am seeing. I've gone from 175lbs to an 197 virtually overnight. I'm gonna order another 4 weeks of this stack and I can't wait to see the final results. Thank you Syntexx Labs you just gained another permanent customer."

"I have been using your Pro Mass Stack for 3 weeks now and I'm amazed! Before I started I was benching 3 sets of 8 at 215 and after two chest workouts I went up to 245 for the same sets. At the end of 3 weeks I was benching 260 for the same amount of reps and sets. It makes me feel stronger when I lift like I don't hesitate to add another 10 pounds on the bar...this shit works...and is well worth it"
