Minimum Effective Dose of HCG While on TRT?

Just curious what you guys have found in your personal experience with this. The last thread I could find discussing this is from 2010.

HCG skyrockets my E2 for whatever reason, bloated within 3 hours, lethargic, etc (confirmed 3-4x with next day bloods). Has anyone had success with like 100-150 IU EOD or even more spaced out for instance with maintaining testicular size?

I am not aware of anyone dosing that low, but 250IU 3x/week and 350IU 2x/week have been effective.

I’ve used 150iu MWF and as low as 50iu MWF with the same effect. HCG definitely spikes e2.

Same effect on fertility, or just the atrophy?

Never checked fertility, I mainly used it for atrophy, sensation, and load volume. I found it effective for those at a low dose.

I needed 1000 IU thrice per week with TRT for fertility for my kids. Atrophy didn’t reverse at all.

When I did a short stint of HCG mono therapy I was prescribed 3000 IU thrice per week.

I can’t see 100 to 150 IU thrice per week doing much.
