i understand how you feel since there are alot of mixed reviews. since i am not a USP labs rep, and the app nut products i will mention i have taken before i became a rep, i will give an honest opinion because i would want the same and i dont want u to blow your money.
It seems like Prime is a Hit or Miss product. For me, it is amazing. my numbers go up on all of my lifts. i have taken it solo twice, and stacked with HGHup once and IGF 2 once. I am not lying...when i stacked it with HGHup, my results were amazing. I did a log of it before i became a rep and the results speak for themselves. if i can find it i will post it on here. anyways, Prime is great alot (for me at least), but even better stacked.
These next products would be a better stack, but it will be more expensive but i will PM you with a discount code you can use if you choose to do it. It is called the Triple Threat Stack by APP NUT. It consists of HGHup, Free Test and Lit Up. I have taken this stack right when Lit Up came out and I fell in love. Now if you just really want to use Prime, this is what i suggest.
2 bottles of HGHup
1 bottle Free Test
1 bottle Prime
1 Lit up (or a pre workout of your choice)
The reason i say 2 bottles of HGHup is because that is where i saw the best results. you will see results with only one bottle, but HGH tends to give better results the longer you are on it.
back to Prime...the reason why alot of users dont like it because its so darn expensive and it only lasts about 3 weeks (69 protocol). others find it ineffective.
