Blended androgens

What do you guys think about this blend I concocted for myself; 100mg drostanolone prop (masteron)/100mg tren hex/100mg primo per ml

planned on taking eod with OT(40mg) and test e(400mg), of course

and arimidex.

any contraindications with this blend?
I'm looking to increase feed effeciency for a low cal diet and intense training, while lowering my bf to aound 3-4%. I have two competitions this summer, geared more towards fitness (running, obsticle-course USMC, pull-ups), the other is a physique comp.

Thanks ahead.

One of the reasons I ask; having two powerful androgens (tren/mast) along with testosterone, all binding well to the AR, in the same stack; will this negate the effectivness of one of the drugs?
