Do the esters in Testosterone cause Water retention?
All esterified steroids do produce a degree of water retention greater than the unesterified version of the same Hormone
This is difficult to show ” in evidence” outside of one comparison
Dating right back to the 1950’s it has been noted that a part of the apparent superiority of testosterone propionate over testosterone suspension is caused by fluid retention and that it actually produces slightly less increase in dry weight than that produced by unesterified testosterone.
So yes.. its fair to say that is true not just in observation but in evidence
