I’d consider adding VAR at the end (30-40mg BID) to help with the water weight and for a little hardening/cut. And I personally don’t want to touch Tren: too many side effects.
For the HCG, get bacteriostatic water, and don’t shake it: gently tumble in your fingers. HCG is delicate. HCG that arrives in liquid state has a shelf life of 20-30-ish days.
