I would come off and recover, 12 weks worth of test and tren is harsh anyway and trying to recover from a 16 wk one will be very challenging to say the least.

Masteron is great for contest prep or cutting cycle, no point in using it if your 14% bf because you wont really benefit from it. Its something to use once your bf is down because this compound is amazing at giving a granite appearance to your muscles and a super hardness what nothing else comes close to
