HCG during cycle and beyond question

[soupeater]

If a person does 250IUs twice a week of HCG on a 4 week Beast cycle (to maintain plumpness and a base of 'natty' T) should they just quit taking it at the end of week 4 or should there be one last larger dose to kickstart PCT (and use up some of the extra HCG on hand before it expires)? I searched and couldn't find anything that specifically talked about that.

TIA
