Strength through the roof!!

I'm a week in to running 30mg/day split AM/PM, while in a slight deficit and only on TRT levels of test. My strength is building very nicely, even while cruising. Set a PR on leg press yesterday. I don't necessarily "feel" anything from the YK such as a PWO boost, but my workouts have really been great this week. Also, super smooth pinning the oil!

started YK11 injectable at a low dose and gradually increased it over the first few weeks. Almost right away I noticed great pumps in the gym and steady weight gain. I’m finishing up at 40 mg a day for my next two bottles. Overall, this is honestly one of the best products I’ve ever taken. Very impressed with the results gonna finish strong .
