Ok so this is my 4th product from USP Labs. I'm currently taking Jack3d and PowerFULL with excellent results. I've also taken Modern BCAA's with good results but switched to Extend for a change of pace. After rave reviews and three pretty decent products from USP I figured I'd give it a shot. When...

If you diet right, drink lots of water, and rip it, you WILL like the results

I am reviewing this as part of the asteroid stack. Let me break it down for you. I did not take any component of the stack by itself, so if your looking for a solo review from me regarding any of these products individually I cant give you one in good conscience. That being said, I had better results...

First off big thanks to Anabolic Adam for sending me out two bottles of prime. As we all know when you see the name USP Labs on a label you are getting an innovative effective product. I finally can say I have taking all of the products USP Labs have to offer and up until Prime I have always been satisfied,...

Ok guys I have not done a review in a while so here goes.
I had the chance a while back to try Prime and wow this stuff is awesome.
I never knew exactly what it was or what all the fuss was about over this stuff... but now I do.
I truly think this is one of the most underrated supps out now.

USP Labs Prime- The Ultimate muscle pill!

First, let me spread a little insight about Prime because I see alot of questions involving what it is and what the ingredients are capable of.
Prime is a nutrient re-partitioner with natural anabolic properties. The product itself is all natural...

Its a nutrient partitioner

Ok, my biggest gripe with this product is the ridiculous marketing and hype. Its a nutrient partitioner which if your diet is in check, you shouldnt even need. I ran 3 months of the Asteroid Stack as instructed by USP Labs and I changed my diet around to include more carbs to compliment the stack and...

Right now I am trying to do anything to keep me from studying, so I thought I'd throw up my Prime review.

Personally I am a huge USP Labs fan, having consistently used 6 of their products, they work great for me. Product claims "muscle gains, thick, dense muscle, strength gains, increased recovery,...

I got the Bonus Size of Prime for about $40 and was a little skeptical on if I was over doing it with Pink Magic, Prime, and Anabolic Pump but I was trusting some serious research and cost comparisons that I did and decided the heck with it I'll give it one month and see what's up. Now I'm not sure I...

I ordered Prime as a nutrient partitioner and to help me put on some quailty mass and basicly it worked haha

Value(7/10): Prime can be a bit pricey depending on where you buy it from. I got it from for pretty cheap compared to and GNC, but it was still a little over a dollar...

I must admit, I was pleasantly surprised with the results

Overall: 10 | Effectiveness: 10 | Value: 10

I have enjoyed by two cycles of Prime. I must admit, I was pleasantly surprised with the results.
Both cycles lasted 8 weeks long and I did the 69 protocol which is 6 days on, 1 day off per week. 9 caps on workout days, 6 caps on non workout days.
The first cycle I gained 11 pounds in the 8 weeks with...
