It does this by increasing levels of neurotransmitters in the brain. These are chemicals that relay messages from your central nervous system to your body. All of these are based around the central nervous system and neurotransmitters. When fully functioning, the neurotransmitter adenosine keeps us calm, relaxed and to an extent sleepy. When inhibited by caffeine it switches these chemical messages off, making you more alert and focused.

Another mechanism will inhibit enzymes that regulate cyclic adenosine monophosphate cAMP — another chemical messenger that controls the central nervous system. It is these mechanisms that may play an important role on how caffeine can affect testosterone levels. Caffeine increases levels of cortisol — a hormone that is triggered by physical of emotional stress.

But it must have popped a question about how cortisol manages to lower the testosterone levels? However, when the stress hormones undergo a drastic elevation, the enzyme fails to protect testosterone from the deleterious effects of cortisol. With prolonged high levels of cortisol, the cholesterol present within the body begins to elevate the synthesis of cortisol; thereby resulting in poor synthesis of testosterone.

Seemingly what causes cortisol elevation should inversely affect the testosterone, and therefore caffeine must act no differently. But on the contrary, there are studies that suggests a positive effect of caffeine on elevating the basal testosterone levels. Research and clinical study indicates that consuming moderate doses of caffeine assists in enhancing muscle endurance and anaerobic performance and if consumed prior to the workout, it boosts the muscular strength to far greater extent on leg press and bench press when compared to placebo.

So, with its cortisol elevating effect how can it positively influence and maximize the muscular strength? Well, studies are here to answer that for you:. Caffeine is known to be a non-selective PDE inhibitor.
