Allopregnanolone
Allopregnanolone is a neuroactive metabolite of progesterone and a barbiturate-like modulator of central gamma-aminobutyric acid receptors that modify a range of behaviors, including the stress response. is a steroid created in the body when progesterone, the female sex hormone, is metabolized. Typically, THP (allopregnanolone) is released in the brain in response to stress, and quiets the neural system within 30 minutes of escalation. This steroid hormone has recently been found to be responsible for the extreme mood swings found in teenagers. In adults and pre-pubescent chlidren THP normally helps soothe the activity of brain cells by binding to GABA receptors that inhibit accelerating electrical activity. However, in pubescent teenagers THP actually becomes a GABA receptor antagonist. GABA (gamma-aminobutyric acid) is the primary inhibitory neurotransmitter in the brain with most sedatives (tranquilizers, anesthetics and alcohol) acting on the GABA receptor.

Epimetendiol
Epimetendiol is one of the major urinary metabolites of the anabolic androgenic compound metandienone. Anabolic-androgenic steroids such as metandienone are some of the most frequently detected drugs in amateur and professional sports. Doping control laboratories have developed numerous assays enabling the determination of administered drugs and/or their metabolic products that allow retrospectives with respect to pharmacokinetics and excretion profiles of steroids and their metabolites. Metandienone misuse can be detected by high resolution mass spectrometry for a prolonged period after stopping the intake of metandienone. Androgenic anabolic steroids are defined as natural, synthetic or semi-synthetic drugs chemicals derived from testosterone, used with the aim to improve physical performance by increasing both muscle strength and mass. Despite their reported toxicological effects on the cardiovascular, hepatic and neuro-endocrine systems, the AAS have been extensively used in sports activities. The use of anabolic steroids was banned by the International Olympic Committee for the first time at the Olympic Games in Montreal in 1976.
