First of all
Sorry for my english, i hope i can make this understandable

I would like to get your opinion on if i should extend my current cycle. The idea was to pack on a little more muscle mass before upcoming competition. stats as now 260 lbs , around 13-15% bf

I'm currently taking
1-5 Test prop
1-5 Tren Ace
1-5 boldenone

I was thinking about extending it with
5-15 Test 500 mg
5-15 Deca 800 mg

6 weeks of Nolva,HCG,Clomid

Then start cutting

Would this be a bad idea? risk of permanent shutdown?
