their 1-t is 1-dhea and that does not convert to estrogen, you def do not want to take an AI with that - as a matter of fact, you'll want to run some sort of base to combat some of the sides - 1-dhea can make you feel pretty sh!tty.
I would recommend running
Dermacrine at the very least through this. If you really want to kick ass, you could run
Alpha Four
by itself, 1-dhea will likely cause extreme lethargy, kill your sex drive, etc...it has no conversion to estrogen or DHT.
For PCT, I would recommend a SERM - I like Clomid, with
Sustain Alpha
Dermacrine is going to really help by providing some necessary estrogen conversion (estrogen is a necessary thing), and also works to mitigate lethargy and improve mood - it's also going to help with libido. This product has been tried and true for well over a decade - very popular to run alongside PHs
Alpha Four is fricken amazing - great for energy, libido, adding some synergistic mass and can also help with leaning. it does cost a bit more, but you do get what you pay for on this one.
Sustain Alpha is going to really help with libido, mood, and to keep estrogen under control - particularly while running clomid (works as a great AI).
