First off it's a 9/10 because IMO no natural supplement exceeds the effects of AAS. With that said here's my review:

To start, I ran this product back in August, ended in September. Before the summer, I was up to 180. My summer was very unsuccessful, though. I dropped to ~160 due to a few factors.. Nearly a month on vacation, a week long bout of the flew, and laziness.

I started this product at @ 171, 13%. I finished at 183 and @ 11%. Overall I was very happy with my gains. I don't know how much I added to my 1RM, but i added 15 pounds to my 6RM, on bench. Gaining 12 pounds and leaning out was very pleasing. The most pleasant factor was that my diet was very inconsistent, and I had an injury which limited me from deadlifting and a lot of leg work. So the fact I gained 12 pounds with out DL and squats is also a nice perk.

Value is more of a 7.5/10. It's a pricey product, I ran the 60ct OG XF, so a 50 day cycle was ~$80 because I found it cheap, but it'd usually be about $100. Still this isn't a product where the price out weighs the effects.

I used 4 caps preworkout on workout days only. And near the end added a 5th cap. Along with my diet off, and limited exercises, I also didn't make a complex stack like most people do. So my next cycle I'll be @ 100%, diet in check, and make more of a stack and hopefully see better results.

Overall, i'd recommend this to anyone with some experience. I think newbies could make gains, but you're better off waiting until everything is in check and making better gains. IMO X-Factor is the best natural supplement!

Overall the greatest supplement I have taken. Took this during my bulk this past winter and have never had better results. I did a 50 day, 2 bottle cycle of the X-Factor Advanced version of this.

As others have said on this product, make sure to get the 2 bottles if you want the best results, as it takes your body sometime for the arichidonic acid to start working. I didn't start seeing great results until a few days into the second bottle where my body really started to change. I used this on a bulk and actually leaned out while on it. Started at 184lbs and 12% body fat and ended my cycle at 192 lbs and close to 9% body fat and I experience absolutely 0 sides while on it.

My strength was also through the roof on this product. I maxed out my 1RM on benching a week before starting and got 265. After the 50 days on this product I finally reached my goal of 300. Truly a great experience on this product.

Value at a 7 because although it is very expensive to do the whole 50 day cycle, the results are well worth it.

Will definitely be buying this again and recommend it to anyone who wants a very potent Muscle Builder with no sides.

Will definitely be buying again.

Let me begin by saying I took the X-Factor Advanced, which is the newer version. It took about 1 1/2 weeks to start feeling the muscle hardness and strength gains I was hoping to get from this product. After about 3 weeks I did notice a great increase in overall vascularity which was great. The one drawback (which I was worried about from the beginning) was that it flared up the pinched nerve in my neck. The directions tell you to not take anti-inflammatories while on the product because it will reduce the overall effects of inflaming the muscle tissue.... which is how the main ingredient works. I, for one am on a steady diet of Advil because of my neck injury. I wish the side effect wasn't an issue, but it was. There were days when I couldn't possibly lift because I was in so much pain.

The price was a bit high. ($79.99) But, when you consider the fact that you don't need to stack it with anything else... I suppose it's not really all that expensive.

I switched over to Prime / PowerFULL (USP Labs) and am very pleased with the results after just 2 1/2 weeks. Even better results strength wise, muscle hardness, but less vascularity.

Tried a bottle didnt do a damn thing for me and I beleive that this acid you can get enough in your meat intake waist of cash.
