Anabolic steroids are drugs which are derived from testosterone, which is a male hormone. Some are in tablet form and others are injected into muscle. Some names of anabolic steroids are: Andriol. Halotestin. Proviron. Sustanon.
Polyvinyl chloride, more correctly but unusually poly(vinyl chloride), commonly abbreviated PVC, is the third-most widely produced synthetic plastic polymer, after polyethylene and polypropylene. PVC comes in two basic forms: rigid (sometimes abbreviated as RPVC) and flexible. The rigid form of PVC is used in construction for pipe and in profile applications such as doors and windows. It is also used for bottles, other non-food packaging, and cards (such as bank or membership cards).
A Petrochemical Product. Although PVC can be produced from a range of hydrocarbons including coal, and derivatives of plants such as sugar cane, the bulk of world production is currently manufactured using the chemical compound ethylene.Ethylene (or ethene) which has the chemical formula C2H4, is a product of the oil & gas industry.PVC is therefore considered to be a petrochemical product.At the start of the ethylene-based PVC production process, the ethylene is combined with chlorine to produce an intermediate chemical known as EDC (ethylene dichloride or 1,2-dichloroethane).he chlor-alkali (caustic soda) industry is often located together with petrochemical complexes or near deposits or rock salt. VCM plants, which use ethylene and chlorine as major raw materials, and PVC plants, are generally located in petrochemical complexes due to this background.
