Once psilocin reaches the brain, it prevents the reuptake (reabsorption) of serotonin, the neurotransmitter that affects our mood, social behavior, memory, and sexual desire.
Interestingly, psilocin actually has a similar chemical structure to serotonin, which enables it to bind to and stimulate receptors in the brain. This amplified stimulation is what brings upon hallucinations — the brain is led to perceive and

THE OXYGEN CYLINDER MAY BE REFILLED WITH PURE MEDICAL OXYGEN BY ANY MEDICAL/INDUSTRIAL GAS DISTRIBUTOR who uses the Compressed Gas Association (CGA) #870 PIN-INDEXED UNIVERSAL COUPLING FOR OXYGEN. Gas distributors in your area may be some of the following companies:
CGA870 valves for:
- LIFE® SoftPac
- LIFE® OxygenPac
- LIFE® Start System
CGA Connection No. 870
USP MEDICAL OXYGEN
- Air Liquide Company
- Air Products Company
- BOC Gases
The liquid air is then transported to huge insulated holding tanks. 4. The liquid oxygen is then boiled to get rid of the nitrogen, since nitrogen has a lower boiling point. The liquid air is then mostly oxygen and transported to large insulated tanks until dispersed into oxygen cylinders.May 13, 2015

The waste products of respiration are water and carbon dioxide, which are removed through the lungs.
was needed to form all acids. Based on this incorrect thought, Lavoisier used the Greek words oxy (acid) and gene (forming) to coin the French word oxygene—translated to oxygen in English—sometime around 1779.
There is yet a third man who is credited for his involvement in the discovery of oxygen in about 1771. Carl Wilhelm Scheele, a Swedish pharmacist and chemist, discovered that a certain element (Scheele also thought it to be phlogiston) was needed in order for substances to burn. Scheele called this element “fire air” due to it being needed for combustion. During these experiments with fire air, Scheele also discovered “foul air,” now known as nitrogen. Despite the fact that Scheele had isolated oxygen before Priestley, Priestley published his findings first.
The raw materials to produce an oxygen tank are liquid air and aluminum. The aluminum starting stock is cast 6061. The liquid air is condensed and heated until pure oxygen remains then distributed into the aluminum tanks. A compressible Teflon ring is used to form the o-ring, which is placed in the o-gland forming a seal between the valve and the cylinder. The o-ring gland is a precision depression machined in the top of the cylinder. When the valve is screwed in the cylinder and when completely seated, it compresses the o-ring and completes the airtight seal between the valve and the cylinder.
- pressurized oxygen is distilled from liquid air in large batches. Air becomes liquid at −297°F (−183°C). The air supply is compressed, then passed through a compartment equipped with a piston (expansion engines).
- As the air expands, the pistons move, increasing the volume of the compartment and decreasing the pressure and temperature of the air.
- The air is then rotated through several expansion engines until liquefied. The liquid air is then transported to huge insulated holding tanks.
- The liquid oxygen is then boiled to get rid of the nitrogen, since nitrogen has a lower boiling point (−320’F; 195°C). The liquid air is then mostly oxygen (97-100%) and transported to large insulated tanks until dispersed into oxygen cylinders.
