Absolutely not bro. That product is a waste of money and will do absolutely nothing for you being on TRT. Don't waste your money on it. I'd check your bloodwork and see where all your levels are....particularly estrogen, SHBG, etc....
300mg per week is extremely high for TRT. Did your doc put you on this? That's like twice what it should be and your estrogen is probably prettydamnhigh if you aren't taking an AI
