Perusing this board I couldnt help but notice the constant references to "cycles" with relatively low levels of testosterone, complaints about how testosterone makes you look "puffy," how other anabolics are so much superior to testosterone and even read someone suggest trenbolone as a first cycle.
If you have zero interest in becoming a successful bodybuilder then by all means pursue drug stacks with low - or zero - testosterone.
The fact of the matter is testosterone is the single most important drug in bodybuilding. First off, the concept of "cycles" is a terrible idea if you are trying to develop an outstanding physique. Do not ever come off testosterone, this should be common sense. You need higher testosterone levels than the human male will naturally produce to maintain - and obviously build - an impressive amount of muscle mass. A typical pro (or any successful bodybuilder for that matter) would have an offseason drug stack based around the "blast and cruise" concept. For example:
Weeks 1-12
4,000mg testosterone in various esters
200mg TNE pre workout
100mg dbol pre workout
100mg anadrol pre workout
1,050mg trenbolone acetate per week
2,000mg equipoise
1,050mg npp
1,000mg deca durabolin
32iu serostim daily
IM 15iu humalog prior to every meal
IM 30iu humalog prior to training
120mcg IGF-1 injected bilaterally in muscles trained
Weeks 13-16
2,000mg testosterone in various esters
16iu serostim daily
1,000mg equipoise
1,000mg deca durabolin
REPEAT to some degree, changing varying drug doses etc.
The point is that testosterone is necessary in large doses to promote muscle growth and size and to maintain that same muscle. In fact, there are a number of current pros whose offseason drugs are simply testosterone, deca, hgh and insulin. Trenbolone, equipoise, etc. often have an extremely amplified effect on metabolism and make it harder to gain weight when testosterone assists in letting most nutrients go into muscular (and yes, fat) storage.
The biggest bodybuilders are on the most testosterone, end of story.
