Triptorelin and HGH need advise from members with experience

[Bevo87]

Ok so I'm currently running 500mg of test e and 300mgs of deca a week. I'm about to add HGH for 6 months to 1yr. My question is once I cycle off the juice can I safely use 100mcg 1 time injection of triptorelin while on HGH? I don't want to trigger negative feedback loop and stay suppressed. Was wanting to use triptorelin(single injection) and 20mg nolva for pct. Any advice is greatly appreciated!
