HUG and how should you use it...

I've read where some prefer to use hcg throughout their entire cycle. Others use it in the second half or near the end. Some don't use it at all.
My question is how well does hcg effect you in terms of recovery? Also, is there any benefit using it throughout your whole cycle vs later in the cycle? Do most use 500/1000iu 2 times a week?
Curious on all responses.

Thanks in advance
