Are you taking any other AAS besides the TREN?

Several studies suggest that in postmenopausal women at high risk of developing breast cancer, raloxifene can reduce the risk of developing an invasive hormone-positive (estrogen receptor-positive) breast cancer. Know more http://www.internationaldrugmart.com/raloxifene.shtml

Ralox, aromasin, caber

What ab your caber or prami? How do you know it's not due to a rise in you prolactin from the tren?

Yes, you can absolutely do this.

300 mg Tren with 150 Test gave me gyno. Yet I can somehow do 750+ Test solo cycles without having any gyno problems.

Tren seems to do this to many people as well. IIRC there is an upregulation of the Progestin Receptor by estrogen, so it is possible that even though your E2 isnt high, the mere presence of Tren set things off.

There is definitely some relation between Tren and E2 sensitivity. On my first run as I waited for the Tren E to clear, I did only 500mg prop and fucking blew up like a water balloon. Mind you I wasn't being good with my AI but I never had such a problem before, especially with Test Prop. This increase in sensitivity to E2 or PR upregulation is likely what causes the libido problems in most instances, and not prolactin (often not off the charts for most people, from what I've seen). I got an increase in gyno on my second cycle and my prolactin was LOW!

Either way, hit that gyno with Raloxifene and hit it hard!!! It got rid of my right nipple gyno completely and most of my left until I started doing a lot of CJC 1295 DAC. Somehow the gyno grew and I wasn't even on cycle. Ralox is doing its work on the left now, though.

Have you had bloodwork done to determine if it's estrogen or prolactin related gyno?
