This should give you a good understanding of tren and how perfect of a compound it is when you’re choosing which AAS to run. In most cases tren should not be run by itself; tren will shut down your natural testosterone production and you’re best suited to stack tren with some form of testosterone. Also, an important note, Trenbolone is typically not suitable for beginners; Trenbolone as we can see is a very, very potent compound and the side effects in some cases can be brutal for some lifters. That is also another reason why Trenbolone Acetate is best in comparison to other forms of Trenbolone. Because it has the Acetate ester attached to it, making it very fast acting and giving it a very short half-life, if problems arise, the lifter can discontinue Trenbolone Acetate and have it cleared from his system very quickly.
For the off-season athlete there is no anabolic steroid more important or beneficial than testosterone. High levels of testosterone will promote significant increases in lean muscle mass and strength. This is assuming that the individual is consuming adequate calories. Compounds like Testosterone Propionate are not magical, you will still need to feed your body enough calories. During an off-season period of growth, this means total caloric intake will need to be slightly above maintenance. This will, unfortunately, promote body fat gain. However, the key to a successful off-season is gaining lean tissue while minimizing body fat gain to the fullest extent possible. By supplementing with Testosterone Propionate you will be able to achieve this more efficiently. High testosterone levels will promote a stronger metabolic rate. This is not a license to eat like there’s no end in sight, but you should be able to make better use of your calories.
