5 weeks into PCT and not seeing much recovery

[Erin]

I agree that HCG can be suppressive but it does depend upon dose surely. If someone takes say 2000iu twice a week they are likely to get HPTA suppression due to higher level of estrogen compared to someone only using 500iu twice a week with minimal suppression?

Would it be wise for me to even try some HCG a couple of weeks after PCT to reverse the atrophy?

I would say it is fundamental to avoid any further HPG-axis suppression when attempting recovery.
Again, HCG during and after (failed) PCT may temporarily decrease symptoms of hypogonadism like testicular atrophy, at the cost of delaying full HPG-axis recovery.
