many years ago I did a few cycles of dbol and test p and I lost the passion for the gym and the body bulding life, then kids came and work kept me off even more from lifting, I just turned 47 and I need to increase my test level and also put up some mass, I was looking for the best test or test blend for adults of my age and all info points me in the same direction, primoteston for mass, enhancing Protein Synthesis and increase production of blood red cells, what would be your advice on dose and running it alone with hcg and also time length for men at my age( 47 years old) thank you guys.
