IMO and experience ....
You are on a cycle now because of the sust dosage. If the test was 100 mg p/w or lower, I'd say you were in HRT.
Adding deca just makes it a stack. I've had good results with deca and test mixed. I get the same strength and weight gain as test alone, plus a lot of joint pain relief.
I also got this with npp instead of deca ... all in the nand family.
Try alternating HRT dosage levels with cycle levels.
HRT: 1 iu HGH eod and 100 mg sust weekly; 0.25 a-dex MWF .... 8 weeks
Cycle: 1 ui HGH MTWThF, 250 mg sust and 200 deca weekly; 0.5 a-dex MWF .... 8 weeks
This is a little bit of a roller coaster ride, but you'll make progressive growth improvements with no big set backs.
You will not like no HRT or cycle. It is like turning into a female/male mushroom.
