tren alone with zero test = no gyno ever
test alone = maybe gyno depending on dosages and if youre prone
test AND tren = higher chance of gyno than test alone
tren causes prolactin to rise. BUT prolactin needs estrogen to cause gyno issues.
no test = no estrogen = no prolactin issues
test = estrogen = maybe issues
test + tren = estrogen + prolactin = probably issues
