The immediate effects of AAS in the brain are mediated by their binding to androgen (male sex hormone) and estrogen (female sex hormone) receptors on the surface of a cell. This AAS–receptor complex can then shuttle into the cell nucleus to influence patterns of gene expression. Because of this, the acute effects of AAS in the brain are substantially different from those of other drugs of abuse. The most important difference is that AAS are not euphorigenic, meaning they do not trigger rapid increases in the neurotransmitter dopamine , which is responsible for the “high” that often drives substance abuse behaviors. However, long-term use of AAS can eventually have an impact on some of the same brain pathways and chemicals—such as dopamine, serotonin, and opioid systems—that are affected by other drugs of abuse. Considering the combined effect of their complex direct and indirect actions, it is not surprising that AAS can affect mood and behavior in significant ways.

Durabolin (Nandrolone)® is a muscle enahancer that is very needed in cutting and bulking cycles. Oregon Labs brand is called Dura 50 which helps you keep the muscle that you gained after a cycle. This product is a must for those seeking pure muscle build-up and a more solid look. You will be very pleased with Dura-50 caps. Novices and less advanced achieve rapid strength and pure muscle gain quick. Dura 50 causes the muscle cell to store more nitrogen than it releases so that a positive nitrogen balance is achieved.


Side-effects from the use of steroids are extremely common and can be quite significant. Most side-effects are reversible once the athlete stops usage although serious long-term side-effects and even death have occurred as a direct result of steroid use.
    •    Decreased sperm production and sex drive
    •    Increased aggression, irritability and mood swings
    •    Liver disorders
    •    Acne
    •    Baldness (alopecia)
    •    Hypertension (high blood pressure)
    •    Raised cholesterol
    •    Gynecomastia (development of over-sized mammary glands in males)
    •    Menstrual irregularities (in women)
    •    Hirsuitism (excessive hair growth occurring in females which follows the pattern of male hair growth, . facial)
    •    Deepening of the voice
    •    Reduced immunity
    •    Possible development of tumors (wilm’s tumor, prostate carcinoma and leukemia have been reported, although a connection is not proven)

The rate of turnover in a metabolic pathway, otherwise known as the metabolic flux , is regulated based on the stoichiometric reaction model, the utilization rate of metabolites, and the translocation pace of molecules across the lipid bilayer . [20] The regulation methods are based on experiments involving 13C-labeling , which is then analyzed by Nuclear Magnetic Resonance (NMR) or gas chromatography-mass spectrometry (GC-MS) -derived mass compositions. The aforementioned techniques synthesize a statistical interpretation of mass distribution in proteinogenic amino acids to the catalytic activities of enzymes in a cell. [21]
