My point here was not that other steroids are harm free but that there are potentially serious side effects that are documented from using trenbolone in equivalent doses commonly used. A review of medline did not reveal any studies for other non-17aa anabolic agents that showed as serious sides. I am not saying do not use tren(I do) I am simply saying, go into it with your eyes wide open and have all the information available. Once again I will credit nandi12 over on trieda for doing this research:

There have been a number of posts recently claiming things like "fina is the safest AS you can do" "fina is not liver toxic",
"fina is not hard on the kidneys", "fina IS hard on the kidneys" etc. Despite all these assertions nobody has posted any evidence one way or the other to support their claims.
This is surprising since there are a wealth of data from animal studies on the toxicity and adverse effects of tren. Many are summarized in an excellent paper at
http://www.inchem.org/documents/jec...ono/v23je03.htm
Here are just a few of the studies mentioned in that report. You can read them and decide how potentially toxic you think tren is:
Male castrated rats weighing 65 - 75 g each were given daily s.c doses of 0, 0.02, 0.1, or 0.5 mg TBA as a solution in sesame oil for 10 days after castration. At sacrifice on day 11, dose-related increases were seen in the weights of muscolo levator ani (maximum +250%), prostate (maximum +1400%), and seminal vesicles (maximum+2500%) in all groups. In this experiment TBA showed distinct anabolic and androgenic activity that was 5 times higher than that of testosterone and 20 times higher than that of 17-ethynyl-19-nor- testosterone (Schröder, 1971b)
For a 100kg (220lb) human these dosage correspond to 0, 27mg, 130mg, 660mg per day
In another study:
Groups of 4 male and 4 female domestic pigs (Sus scrofa) were fed diets containing 0, 0.1, 2, or 20 ppm TBA (equivalent to 0, 4, 80, or 800 µg/kg b.w./day TBA, respectively) for 14 weeks.
(note: these doses correspond to 0.4mg, 8mg, 80mg per day in a 220lb human)
There were dose-related decreases in blood levels of testosterone and estradiol in males in all dosed groups (both maximum -95%, significant); progesterone was markedly decreased (maximum -99%, significant) in females in the two highest-dose groups. In the same groups, there were dose-related changes in the absolute and relative weights of the liver (maximum+30%, significant), uterus (maximum -50%, significant), kidney(maximum +25%, significant), and testis (maximum -55%, significant). In the highest-dose group changes were observed in the weights of the pituitary (-15%, significant) and seminal vesicles (+280%,significant). There was an increase in thyroid weight at all three dose levels (maximum +20%, not significant).
Histopathological examination showed the following dose-related abnormalities in the 2 and 20 ppm groups: in the liver, enlargement of the hepatocytes with associated ground glass appearance of the cytoplast; in testes, moderate to complete interstitial cell atrophy (with normal spermatogenesis within the seminiferous tubules);
Yet another study:
Groups of 64 male and 64 female Swiss albino CFLP mice, weighing 22 - 25 g each, were given diets containing 0, 0.5, 1.0, 10 or 100 ppmTBA (equal to 0, 0.004, 0.09, 0.86, or 8.6 mg/kg b.w./day TBA for males, respectively, and 0, 0.005, 0.10, 0.96, or 9.5 mg/kg b.w./day TBA for females, respectively) for 95 - 104 weeks (the test was endedwhen survival was 20% in males or females in the control group). After13 weeks 12 mice/sex were killed. At that time significant increases were observed in the absolute and relative weights of the kidneys in males and females at 100 ppm (20 - 40% increases). Significant decreases were seen in the weights of the spleen of top-dose females (-20%) and significant increases were seen at 1.0, 10, and 100 ppm inmales (+25%).
Terminal gross- and histopathological examination showed an increase in liver nodular hyperplasia and dose-related tumours in the male dose groups;these increases were statistically significant at the two highest doses. The incidence of liver tumours was also increased in females in the highest-dose group (8/52 versus 4/51 in controls). There was an increase in incidence of hepatocyte vacuolation in males in the100 ppm group. In 100 ppm females, gross pathological examination showed an increase in the incidence of enlarged and swollen kidneys, accompanied by a marginal increase in the incidence of nephritis.
Dozens more summaries of studies like these can be found at the website above.

My guess would be that if tren causes increase in organ weight then all steroids do too. In fact I have heard that steroids can cause increase in organ weight and especially an enlarged heart if used very long term in large doses. This is very old knowledge....I am going back to the late 1970's.
