I Gotta Give napsgear a lot of credit. They are hands down the best source I have used before. Been on their products for 5 weeks. The injections are smooth as butter I’m using testosterone and Primo from them. Doing quite a bit of volume three CC’s a week of the primo and two CC’s a week of the testosterone. I’m mixing them up and injecting them and I’m not having any sort of issues at all in terms of redness or swelling. Most importantly my results have been fantastic I’m gradually gaining lean muscle mass.
