Before using this product I've previously been using Jack3d. I was strapped for cash and all the ads I've seen for it says it has the same formula as Jack3d so I'd thought I'd give it a shot. I was disappointed in the following ways. When I would take Jack3d I would lose any and all sleepiness I may have felt. If I didn't really feel like going out to lift that would change almost instantaneously after taking Jack3ed as well. But while taking Massive Growth, I did not achieve any of the benefits I listed while on Jack3d. I was still able to perform in the gym but I feel not as well as when I was on Jack3d. Also the lemon-lime flavor is awful, it's just so bland. Although it's not that big a deal it's just hard to stomach. Another thing I did not like about this product is that it doesn't come with a scooper and it doesn't tell you how much water to stir the powder in with, so that was inconvenient. I can't really complain much because you get what you pay for ($12.99 from Supplement Warehouse.)Unfortunately, I would not recommend this product, unless you get it real cheap because it is better than nothing. However, I know that different products work for different people and the fact that I was already accustomed to pre-workout supplements could have played a role in the ineffectiveness of this product for me.

This product has served me well! Bought my first tub when i was strapped for cash and wanted Jacked. But, I am happy to say I was pleasantly surprised at the effectiveness of this product.

Value- cant beat it. I get this for 12 dollars online...

Pump- actually very good all things considered. I would say comparable or even better than Jacked. Deffinately last until the gym the next day

Focus- awesome. You can feel the head change as soon as you drink it. No fooling around at the gym. Keeps you glued to the weights

Recommendation- In a heartbeat. Great overall product. Don't be turned off by it's cheap price. It works well. Just don't get lime=)

i bought this with the huge impact stack this and 5 pounds of protein for 39 bucks pretty good deal, i have found this for 19.99 in a lot of stores with 45 servings its really a bang for your buck. The pump is pretty good i think its better than Jacked personally, very good energy through my work out and really gets me focused. I will be buying a new jug when this one is gone, if your looking for a new pre workout i would definitely check this out!

They advertise this as a Jack3d competitor. I've tried both and see different results from each. Jack3d carried me further through a workout, but Massive Growth put more size on my frame (about 2 pounds of growth and increased strength roughly 14%). The taste is comparable to ground up aminos, but I'm not in this for a delicious pre-workout treat, I want results. Bottom line, if you need size, go with Growth, if you need energy, go with Jack3d. Dollar for dollar, it's a good deal. I may try mixing half of each to see if I can get both.

This is an pretty good pre workout. It provides great pumps and tons of energy. I didn't notice any crashes either. It basically seems to b like Jacked but a lil stronger. This product caused some itching and redness. I've read other reviews on it and it seems to be pretty common side-effects. I would def use again.
