    Dose Change Side Effects

    Hi guys, I just switched to a daily protocol of 24mg after spending a few weeks on 100mg E3D. This E3D protocol kicked the shit out of me, I dont think I respond well to having so much T at one time. The anxiety and thoughts were nightmarish plus the lethagy is real. Is there anything that...

    High T, Low E2

    Hi, I am currently injecting 50mg of Test E E3.5D. No AI. Whilst my T levels are looking great, the same cannot be said about my E2. I am experiencing pretty much every low E2 symptom under the sun. Would injecting 100mg once a week help boost these levels? Thanks for listening. Az
