ok, so I was reading up on Tren in the profiles section...

and noticed some conflicting info regarding the estrogenic sides...
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) accelerated fat gain, decline in fat break down and water retention trenbolone. Trenbolone is also resistant to the 5- alpha-reductase enzyme, this enzyme reduces some steroid hormones into a more androgenic form, in trenbolones case however this does not matter, trenbolone boasts an androgenic ratio of 500, it can easily cause adverse androgenic side effects in any steroid.com members who are prone cases of hair loss, prostate enlargement, oily skin and acne have been reported. Unfortunately trenbolones potential negative side effects do not end there. 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 (18). No need to panic though, the anti-estrogens letrzole or fulvestrant can lower progesterone levels, and combat any progestenic sides. The use of a 19-nor compound like trenbolone also increases prolactin…. bromocriptine or cabergoline are often recommended to lower prolatin levels (20). Testicular atrophy (shrunken balls) may also occur; HCG used intermittently throughout a cycle can prevent this. (21) It is also wise for Tren users to closely monitor their cholesterol levels, as well as kidney function and liver enzymes, as Tren has the potential to negatively affect all of those functions. Trenbolone, being a powerful progestin, will also shut down natural testosterone production which even a relatively small dose and keep the testosterone level suppressed for an extended period of time, this can lower libido and cause erectile dysfunction (fina dick). It is essential that you always stack trenbolone with testosterone.
So which one is it? Never used Tren myself but I plan to in about 9 months from now so Im gathering as much info as possible and this will probably help others new to Tren.
thanx,
