Good afternoon Dylan. First I’d like to say thank you for all the knowledge you drop on YouTube you seem like a good hearted person that actually really cares about people’s health. I have been on a tren ace and test cycle for 4 weeks so far. Running 250mg tren ace and 250mg test cyp a week. I’m pinning Monday thru Friday .2 test and .5 tren which equals to the amount 250/250. I’m taking proviron twice a day 25mg tabs. I am taking cabergoline .5 Monday Wednesday and Friday. And was taking arimidex .5 eod but now I have added Letrozole instead because I think I’m having early gyno symptoms. It started early week 3 my nipples have been getting real sensitive just from my shirt which never happens and get puffy at different times of the day. I feel extra fat on them too and has really been affecting me mentally as I know it would to every man specially since I’m on a cut and eating clean. My question to you is how long until Letrozole starts working ? It’s been a week I have been taking one everyday but going to taper off to twice a week after it stops but it hasn’t. What did I do wrong with my cycle I feel like I have moderate doses and have the prolactin and estrogen ancillaries I needed. Should I drop the tren and continue with the test to see if the tren is causing this? My nipples are not lactating just sensitive and feel like a ten year old chubby boys breast. I’ve always had a pretty solid chest but now as much as I flex I can pinch fat. Should I just stop my cycle all together? Please help I don’t want this to turn into full on gyno to where I need surgery. Thank you Dylan in advanced. And btw no it’s not my first cycle I have ran about five cycles that have been test only have ran deca and test cycles and test and tool. Have a great rest of your day.
