Androstenolone

Niacinamide
Also known as nicotinamide. A form of the B-vitamin niacin that has vitamin activity, but does not cause flushing or reduce cholesterol. Niacinamide is frequently used in multivitamins and fortified foods. It’s also used topically due to its anti-inflammatory and anti-aging effects.
Picamilon
A niacin-bound derivative of the inhibitory neurotransmitter GABA (it’s also spelled pikamilon). Picamilon has been extensively investigated in Russia, but little researched in the West. It allegedly increases cerebral blood flow and induces a state of relaxation, without drowsiness.
Xanthinol Nicotinate
Also known as xanthinol niacinate and Complamin (commercial formulation). Xanthinol nicotinate is a combination of xanthinol (a derivative of theophylline) and the B-vitamin niacin. It’s considered to be a “smart drug” or nootropic, due to its ability to improve memory and microcirculation. Flushing can occur with higher doses, although this reaction does not occur as frequently as it does w/niacin, its parent compound.
Niacin
Also known as Vitamin B3 and Nicotinic Acid. Niacin is part of the coenzymes NAD and NADP (nicotinamide adenine dinucleotide and nicotinamide adenine dinucleotide phosphate), which are primarily involved in oxidation-reduction reactions throughout the body. In addition to maintaining basic health/wellness, niacin is used in the treatment of high cholesterol and cardiovascular disease. Due to the potential for side effects and hepatotoxicity, however, high dose niacin should only be taken under medical supervision.
Other forms of niacin include niacinamide, xanthinol nicotinate and picamilon.
