My liver and kidney values were absolutely normal after eight weeks of 75mg/day and four weeks of 150mg/day. Tren is great while on, but for me, keeping the results proved impossible. Granted, I do not utilize the standard array of post cycle ancillaries, and that may well be a factor here.
In terms of animal vs. human thinking...humans are animals. The molecules do not differentiate.
Not to mention trenbelone, as mentioned, has been manufactured and utilized for human consumption.
The parent molecule for deca and tren is the same. Where is the logic supporting increased sides from tren from a toxicity standpoint?
I have yet to find any evidence supporting the notion that it is the trenbelone causing kidney stress. My guess is that it is an abundance of oxidized methylcellulose that is the culprit.
I have to agree that tren does tend to castrate after a while. Certainly something to consider when picking your route.
As for aggression, there is a little, but interestingly I have found that ox makes me more irritable than anything else I have tried, with the exception of halo.
I guess I have to point out that for a guy who has tried so many drugs, I do not have the corresponding muscle mass/base to offer good advice in that context.
Of course, I take months off at a time and stay under 8% year round, so take that into consideration as well.
For me, in the end, tren is a pretty good choice, but not better than ox/test.
