This is my 4th cycle:
16 week cycle Sustanon 350: 500 mg / week FOR 16 weeks
Boldenone 500: 700 mg / week FOR 16 weeks
Trenbolone 200: 400 mg / week FOR 10 weeks (stated 3rd week ~ 13th week)

I am currently on end of my 5th week.

The situation is I had 1 vial of Boldenone from last cycle which I used for my 1st ~ 5th week, and 2 vials of Boldenone was supposed to be delivered last week but it got stuck on ISC for a week.(I assume it is confiscated.)

My questions are,

1. Will it be okay to run just sustanon and trenbolone through out my cycle?

2. If Boldenone arrives by the time I have less than 8 weeks left on my cycle should I still used it? or just save it for my next cycle?
