HCG nat test on cycle and keeping strenght

[SoulP]

Hey fellas. I have a Q that I can't seem to get answered.

Say I have a natty test level around 950 how much of that natty test would be continued to be produced if I took HCG under a test cycle?

I'm asking bc. i have had one previous test e cycle, with great gains but a drastic loss of strenght under PCT.

And lastly, would running HCG under a whole cycle allow one to run longer cycles?

Cheers
