3 weeks on test….

….and I don’t ever want to come off. My levels were 400s previous to this and the main thing I love is I’m not always fatigued now. Used to always need to cat nap for 30-45 mins around 7-730. Strength has increased on a few lifts mainly biceps and back, which were my stronger lifts to begin with, but overall nothing too crazy. Sexual endurance and appetite up. I’m already looking into things like primo and test for my next run. I read somewhere it is advised to pct after first run. Is that necessary? How long before I hop on something else. Assuming the answer is when my baselines are in order, but what does that generally look like? 12 weeks? 16?
