Since your cycle is almost over, the option to run HCG during the cycle has passed. If you run it during the cycle to maintain testicular volume then there's no need to have a long run of it at the end.
You're on short esters so you'll have some overlap of HCG usage and aas injections. You want to run the HCG to be finished with it a few days before you start your intended PCT.
My own preference is 1000 iu EOD for 10 days or 500 iu ED for ten days. Take a look in the PCT forum for more alternatives. Since you mention that your cycle is almost over, some of the other protocols might no longer be an option for you.
Assuming you've already mapped out when you end your cycle and when to begin PCT, count back a few days, three or four, and then count back another ten days. That's when to start your HCG protocal if you do a ten-day run. As I said, end your HCG just before you move onto the clomid etc.
You can run the clomid at a flat 50mg ED for 3-4 weeks. I wouldn't run the Nolva after running tren unless you've done it in the past without any gyno issues. There have been debates on here about it but there are suggestions that Nolva can increase the likelyhood of gyno after running tren.
After all this time, why is there not a sticky for HCG usage?
