400mg took my bench from 265 to 330 in 10 weeks at 44 yrs old. I battled internally with how much to take and wanted to take 800mg. Then a trusted friend told me to cut it in half and just see what happens. I'm so glad I did. Just finished the test only cycle last week and after blood work I have a good foundation of what test only can and will do for me. Thanks for the advice given by Dylan Gemelli's youtube videos and a trusted friend. Start low then you get the excitement of your next cycle and what adding another compound can and will do for you. Best of luck in your endeavers.
