I have run nolva and it worked well, no sides for me at 20/20/10/10, but I did feel like it took me all 4 weeks to get back to normal tbh. I have clomid for my next cycle and I heard as far as getting your test back in check clomid works faster than nolva, but nolva is better if you have gyno concerns. Either way you can't go wrong and if you're super nervous about it you can always run both. I personally would go with the Arm1care + Tudca combo. You can use the dermacrine in place of the 4 andro and you won't have to worry about estro sides. Believe me, I was super skeptical of dermacrine and I used it for my last Super Dmz 2.0 cycle and libido was up and lethargy was almost nonexistent. It definitely does the trick. I weigh about 225 though so I used 5 pumps a day. If you do want to run 4 andro, yeah try the exemestane EOD at 12.5mg. I personally have used 4 andro twice and have not experienced estro sides other than bloating/water retention. Eat eat eat 4000 cals+ daily if you want to hit those PR's. You won't have to worry about estrogen during PCT just take your SERM and a natty test booster and you should be back to normal by the end of PCT. Ive also heard of guys getting their wives pregnant while on cycle, so no worries you will still be able to have babies my friend lol
