In all honestly you don't need the milk thistle, 1-Alpha is not liver toxic. At the dose you are taking it although you will see some gains, it will be very mild on your system so not even 100% sure there is a need for the Cycle Support. If you take it you can take it exactly as directed since the liver stuff in it will not have a negative effect on the PH like it does with a methylated product.
Your PCT sounds very good for the dose you are taking of 1-Alpha. Will definitely be sufficient.
