Figure 11-1. Arousal spectrum of sleep and wakefulness . One’s state of arousal is more complicated than simply being “awake” or “asleep.” Rather, arousal exists as if on a dimmer switch, with many phases along the spectrum. Where on the spectrum one lies is influenced in large part by five key neurotransmitters: histamine (HA), dopamine (DA), norepinephrine (NE), serotonin (5HT), and acetylcholine (ACh). When there is good balance between too much and too little arousal (depicted by the gray [baseline] color of the brain), one is awake, alert, and able to function well. As the dial shifts to the right there is too much arousal, which may cause hypervigilance and consequently insomnia at night. As arousal further increases this can cause cognitive dysfunction, panic, and in extreme cases perhaps even hallucinations. On the other hand, as arousal diminishes, individuals may experience inattentiveness, cognitive dysfunction, sleepiness, and ultimately sleep.
Steroids can make pimples pop up and hair fall out. They can make guys grow breasts and girls grow beards. Steroids can cause livers to grow tumors and hearts to clog up. They can even send users on violent, angry rampages. In other words, steroids throw a body way out of whack. Steroids do make users bulk up, but the health risks are high. It's true, on steroids biceps bulge; abs ripple; and quads balloon. But that's just on the outside. Steroid users may be very pleased when they flex in the mirror, but they may create problems on the inside. These problems may hurt them the rest of their lives. As a matter of fact steroid use can shorten their lives.
It is very common for bodybuilders to use veterinary steroids for a precontest cycle. Since they are typically assimilated quickly, they do the best work in the shortest amount of time, and are generally out of the system relatively fast in comparison to other ‘roids. And, believe it or not, usually people see fewer side effects when using vet products than when using human ones. Why take anything else? Maybe not ‘why take anything else’, but why not include veterinary steroids, in one form or another, in every cycle? In my mind, veterinary drugs should really be everyone’s choice for extreme condition and definition. They combine well with androgens and other anabolics as well as any drug in the human realm of anabolic steroids. The only problem, these days anyway, is availability. You can find them in Mexico, but you risk fakes, counterfeits, lower quality, or lower dose per ml. You also, of course, face the possibility that you’ll be stopped.
