When I was big into cars, I always told myself and my wife I was done buying parts for it lol. That was always a lie.
That, I believe, is a more personal question to answer. I like short esters because you feel them quicker and they clear quicker. BUT I hate pinning super frequently. I say that, but also note that my last 3 cycles have all been short esters.
Any time I try a new compound, I generally prefer short esters for compounds with extreme or pronounced sides. I do not believe MENT is one of those compounds that would be required to have a short ester though, because the only real issues anyone seems to have with it is E2 sides.
With all of that said, I think you would be fine with MENT D, but I wouldn’t start higher than probably 100 mg/wk (which I guesstimate to be about the same as 10mg/day MENT A based on ester weight) until you know how you react to it. Also make sure you have an AI/SERM on standby if you’re running with moderate or high test.
