Mag10 & deca/tren?

I’m having a hard time finding some Test so I was wondering if stacking Mag10/Tribex with deca300 would work.(I know this board hates deca but my resources are very minimal) I also have tren75/20ml. My question is do you think the Mag10/Tribex will balance out the hpta suppression and post cycle drop of either? I was thinking about 12weeks of Mag/Tribex stopping the deca on the 8th week.
