I too am interested in doing "Masteron HRT" or "Stasis" at 100mg/week instead of Test.
For stasis/bridges, if it keeps the libido going, and lets the natural production come back faster than doing the same on Test, it's a winner.
For HRT, it might be a welcomed change to using Test constantly, say for 4-6 weeks before switching back to Test. I know we produce Test everyday (!), but using exogenous hormones might just create some issues eventually. Many people on TRT say they feel great at first than not so much later on, and blame that on screwed up E2 levels, which might be exact, but there might be some other reasons as well.
Anyway, interesting subject! Prisoner, who popularized the Test stasis/taper protocol here on the forum, actually suggested that people could use 50/50 Masteron/Test instead of all Test. I did that and had my easiest transition to "off" ever. I did suffer from acne that still lingers to this day and wasn't there before though.
Let's just say there's more real world "research" to be done but I'm sure we'll find better ways to use and go off PEDs that we do now.
