well Im not going to say Tren is better then test but heres somethign I pulled off the net
TA is a testosterone analogue that is 10-50 times more active in the human body than testosterone. Users of Finaplix see great mass and strength gains. TA does not convert to estrogen so users will see no water retention. However, although TA does not aromatize there are many instances of gyno in its users. This is a very strong drug and one of the first side effects users see is a darkening in urine color. This is a sign of kidney damage. It has been noted that TA is also very effective at burning fat, making Finaplix very popular amongst pre-contest bodybuilders. Not only does TA improve nitrogen retention, but it also raises many hormone levels. In a study performed by the Department of Animal Sciences, rats were injected with Trenbolone Acetate daily for two weeks and then were tested for an increase in growth hormone (GH), insulin-like growth factor (IGF-1) and fibroblast growth factor (FGF). Not only did treated rats grow more rapidly, deposit less bodyfat and retain more protein, but satellite cells cultured from the Trenbolone-treated rats exhibited greater sensitivity to FGF and IGF-1 than cells cultured from control rats. This increased sensitivity was also accompanied by increased levels of GH, IGF-1 and FGF in the bodies of the rats. With an elevated cocktail of these growth promoting hormones flowing in an animals body, it cannot help but grow. Not only are the cells more sensitive to these hormones, there are more hormones available to utilize. It would be safe to say that similar kinds of hormonal increases and sensitivities would also be found in humans that used Trenbolone Acetate. A large increase in these hormone levels would not only help with growth, but would sky rocket the effectiveness of this drug due to the cocktail of the anabolic hormones present in the body. What makes TA so attractive to bodybuilders and strength athletes is the incredible cosmetic and strength-producing effects it has on the body. Users report a dramatic increase in strength and muscle density along with anoticeable increase in fat loss.
