Effectiveness milligram per milligram: One way is, having the rest of a stack already, and wanting to add X mg of boldenone, or the same mg of Masteron Dromostanolone Propionate.
To some extent it would depend on what the rest of the stack was, but in most cases I’d call this a pretty even match.
Cost per milligram: Another would be, having the rest of a stack already, and having $X to spend on either Equipose Boldenone undecanoate liquid or Masteron. Usually the answer would be, whichever is cheapest per mg. I think this would usually be the boldenone but not always.
Side effects: Still another would be, having the rest of a stack already, and picking appropriate doses for each drug, considering side effects. Depending on preferences or on the rest of the stack, Masteron would win in many cases; boldenone in some others.
When looking at side effects, it’s always necessary to look at the sum total of the stack. Too often an individual component gets blamed, when the problem is that that the total was simply too much, and omission of another of the compounds would also have avoided the problem.
I don’t think Masteron is the slightest bit worse than anything else when it comes to hair loss or effect on the prostate for any given amount of anabolic effect.
But if you had what was a substantial steroid dosage already and then added another steroid to it, the total could easily be more than personally suitable for you.
However if you used it alone and found it unsuitably harsh for you, that would be a different story. That would be unusual though: I’ve never encountered it.
Single steroid stack: THEN you have the question of using by itself.
I have used only Masteron and boldenone in a cycle for myself only once: I’ve never had anyone else using it.
It was Masteron propionate 100 mg/day, boldenone propionate 50 mg/day, so just over a gram per week total. Nice. Nothing wrong with it at all, I’d be fine with doing it again.
The Dromostanolone enanthates would have been more convenient as it was an 8 week cycle and would be fine, but propionates were what was on hand.
