Apparently it seems possible, but not probable according to reports from many users and not a widespread concern from triacana users worldwide. Although you
may have a valid point, consider this:
1. Triacana has been around for years and years without serious concern for gyno. Europeans have been using it much longer/more than the U.S from what I have read, and there has never been a widespread side effect of gyno.
2. You have been using M1T, a potent androgen. Even though you have used Nolva for PCT therapy, this is not set in stone that you cannot get gyno. Considering that gyno is most common in these circles from using androgens, which you have, doesn't it seem logical to you that M1T would be more likely to be the culprit?
Even
if you got gyno from hyperthyroidism, you would seem to be in the overwhelming minority, unfortunately for you. Your source of "proff" is simply an article stating that gno may be caused from hyperthyroidism.
I would ask that you do not state "proof" that Tri-max caused your gyno unless you have something other than an article stating that hyperthyroidism (a condition that may be caused by Tri-max) may be a possible cause of gyno. What you do not have is a source of figures showing percentages of cases of gyno that could be attributed to hyperthyroidism, androgens, other drugs, etc.
Considering your use of an anabolic compound, it just seems that using Ockam's Razor* (the simplest explanation of the solution should be taken first, as opposed to a more complicated one) one could easily conclude that M1T woulod more than likely be the culprit, not the Tri-max.
*I conceed that not all in science use this type of logic, but in some cases it seems to work for me
Bottom line: IMHO, Tri-max and its associated condition (hyperthyroidism) could have caused your condition, but it seems unlikely given your other drug usage.
