Re: How much calories undermaintenance using PH?
^^^ PH will NOT prevent ALL muscle loss - sorry pal but where do you come up with something like that??
PHs promote an anabolic environment no doubt, but will not stave off catabolism entirely in the absence of proper nutrition and sufficient macros for the individual's needs.
To the OP, the advice from Simon re lowering carbs above would be the route I'd consider too, I'd maintain protein at 2g/kg of lean body mass for satiety and muscle retention, maintain fat intake (which will also help with post cycle recovery) and lower carbs accordingly to hit my daily calorie target.
