I love me some napsgear products. They are one of the best you will find. Let me tell you a quick story of how I used 500mgs of test and ran primobolan alongside it with a lot of success.
I started at 500mgs a week of each. Then I kept the test dose the same and increased primo to 800mgs. Had some magical results. I feel like I am of the golden era and so happy. Def use them they are worth it!
