FDA on:

Inactive ingredients: pharmaceutical necessities and excipients with the exception of the active ingredient.

Sucrose: A nonreducing disaccharide composed of 50% GLUCOSE and 50% FRUCTOSE. Linked to liver toxicity and severe non-immunologic anaphylactoid reactions.

Hydrolized gelatin: “cooked” form of collagen [collagen: “Collagen is the most abundant protein in the human body, found in the bones, muscles, skin, and tendons. It is the substance that holds the body together. Collagen forms a scaffold to provide strength and structure. Endogenous collagen is natural collagen that is synthesized by the body and has a number of important functions. Exogenous collagen is synthetic. It comes from an outside source, such as supplements. Exogenous collagen is used for medical and cosmetic purposes, including the repair of body tissues.”] [sources: hydrolized gelatin — ; & collagen — ]

Sodium Chloride: salt 

Monosodium L-glutamate (MSG): sodium salt of glutamic acid, conjugated with L+ anion. [great reads on it — ; & ]. MSG is a flavor-enhancing Chemical to make food taste better. It in large is your taste buds to enhance the perception of savory taste.

Sodium Phosphate dibasic: a Phosphate is a chemical derivative of phosphoric acid. The phosphate ion ³⁻ is an inorganic chemical, the conjugate base that can form many different salts. In organic chemistry, a phosphate, or organophosphate, is an ester of phosphoric acid. Sodium phosphate is used as an anti-coagulant/anti-caking agent and to adjust the PH level of processed foods.

Potassium phosphate/chloride: Monopotassium phosphate, MKP, (also potassium dihydrogenphosphate, KDP, or monobasic potassium phosphate) is the inorganic compound with the formula KH2PO4. Together with dipotassium phosphate (K2HPO4.(H2O)x) it is often used as a fertilizerfood additive, and buffering agent. The salt often cocrystallizes with the dipotassium salt as well as with phosphoric acid.[4] Single crystals are paraelectric at room temperature. At temperatures below −150 °C (−238 °F), they become ferroelectric. Potassium chloride (also known as KCl or potassium salt) is a metal halide salt composed of potassium and chlorine. It is odorless and has a white or colorless vitreous crystal appearance. The solid dissolves readily in water, and its solutions have a salt-like taste. KCl is used as a fertilizer,[7] in medicine, in scientific applications, and in food processing, where it may be known as E number additive E508. In a few states of the United States, it is used to cause cardiac arrest, as the third drug in the “three drug cocktail” for executions by lethal injection. It occurs naturally as the mineral sylvite, and in combination with sodium chloride as sylvinite.

MRC-5: MRC-5 (Medical Research Council cell strain 5) is a diploid human cell culture line composed of fibroblasts derived from lung tissue of a 14 week old aborted caucasian male fetus.[1][2] The cell line was isolated by J.P. Jacobs and colleagues in September 1966 from the 7th population doubling of the original strain, and MRC-5 cells themselves are known to reach senescence in around 45 population doublings.

EDTA: an aminopolycarboxylic acid and a colorless, water-soluble solid (synthesized). Its conjugate base is ethylenediaminetetraacetate. It is widely used to dissolve limescale. Its usefulness arises because of its role as a hexadentate (“six-toothed”) ligand and chelating agenti.e., its ability to sequester metal ions such as Ca2+ and Fe3+. After being bound by EDTA into a metal complex, metal ions remain in solution but exhibit diminished reactivity. EDTA is produced as several salts, notably disodium EDTA, calcium disodium EDTA, and tetrasodium EDTA (typically as the hydrate). [interesting article on its function in binding to heavy metals to “remove from blood” (chelation) — ]

Neomycin: an antibiotic. [side effects/warning for oral, but what about INJECTED? — ]

Fetal bovine serum: Fetal bovine serum comes from the blood drawn from a bovine fetus via a closed system of collection at the slaughterhouse. Fetal bovine serum is the most widely used serum-supplement for the in vitro cell culture of eukaryotic cells. It is used as a growth supplement.

Polysorbate 80: Polysorbate 80 is a chemical used by physicians to open the blood-brain barrier, for the purpose of chemotherapy for brain cancer. The chemicals then bind tightly to the polysorbate 80 and the chemo can reach the cancer cells. Polysorbate 80 is used in vaccines to reduce the surface tension of the chemicals, and increase the solubility of chemicals that normally would not be able to dissolve together (think oil and water). It also works as an emulsifier so the chemicals can disperse evenly upon injection.
