what are your stats?
a good bulker is 500 test, 300-400 deca (depending on your weight), 30mg dbol. running deca for 8 weeks and test for 11 weeks. dbol for 3-4 weeks. the cycle you are running is for someone who is competitively bodybuilding and doesn't care if they wreck their HPTA. the cycle I outlined is enough for a gym rat to get very good mass and strength.
deca esthers linger for a long time. running it 15 weeks is like running it 20+ weeks. and then running tren towards the end also. your HPTA will be fried my friend.. I would re-think this cycle unless you don't care and are planning on HRT anyway. I applaud you for running a long PCT but it will be a rough recovery on this cycle... very very fun while on and very very sucky after.
