In the steroid profiles section it says tren :Trenbolones chemical structure makes it resistant to the aromatize enzyme (conversion to estrogen) thus absolutely no percentage of trenbolone will convert to estrogen. Trenbolone administration would not promote estrogenic side effects such as breast tissue growth in men (gynecomastia, bitch tits)
But then it says: Trenbolone is also a noted progestin: it binds to the receptor of the female sex hormone progesterone (with about 60% of the actual strength progesterone) (17). In sentitive steroid.com members this can lead to bloat and breast growth worse still, trenbolones active metabolite17beta-trenbolone has a binding affinity to the progesterone receptor (PgR) that is actually greater than progesterone itself.
Isn't that an oxy moron? first it doesn't cause bitch tits, then the second one says it does. Can someone explain this to me?
