Creatine Phosphate Disodium Salt Tetrahydrate Technical 98%

Quantitative in vitro determination of creatine kinase in human serum and plasma. Used in diagnostics for creatine kinase test. Creatine Kinase catalyzes the transfer of a phosphate group from the creatine phosphate substrate to ADP. Subsequent formation of ATP is measured through the use of two coupled reactions catalyzed by hexokinase and glucose-6-phosphate dehydrogenase (G6PDH) which results in the production of reduced b-nicotinamide adenine dinucleotide (NADH) from b-nicotinamide dinucleotide (NAD). This change in absorbance is directly proportional to the activity of creatine kinase in the sample.

Creatine phosphate disodium salt tetrahydrate is used as a substrate for the assay of creatine kinase.

Dromostanolone propionate, also known as drostanolone propionate after a long period of time as a rare drug is now enjoying greater popularity, and deservedly so. 
Where one does not wish to use a large amount of injectable and wishes to use either no trenbolone or only a modest amount of that drug, Masteron is often an ideal choice for inclusion in a steroid stack, or in some cases for use as the sole injectable for a steroid cycle. 
Drostanolone propionate is used primarily by athletes who need to retain strength while losing mass. It is beneficial to runners and athletes who must remain in a certain weight class. 
Drostanolone propionate can increase muscle hardness and density, giving an individual a more complete appearance when competing on stage. 
Drostanolone propionate can promote increased strength while keeping body fat the same or even lowering it, something can help to prevent muscle loss while dieting

Povidone Lodine Description:
PVPI (Povidone Iodine) is a stable chemical complex of polyvinylpyrrolidone (PVP) and elemental iodine, which is completely soluble in water, ethanol etc. PVP-Iodine can extinguish bacterial, virus, fungus effectively. It is a stable complex with no irritation, which can dissolve in water completely.
PVPI is the complex compound of PVP K30 and iodine, it has powerful bactericidal action to germ, virus,fungus, mold. It is stable, has no irritation and can dissolve in water completely. We also invent high-stable PVPI which is called YK-1032 by our own R&D team.
Povidone Lodine Application:
Povidone Iodine is the complex compound of PVP and Iodine. It has powerful bactericidal action to germ, virus, fungus, and mold. Its microbicidal potential and microbicidal spectrum is equally the same as those of Iodine. PVPI retains the most valuable advantages of high efficient partial disinfectant Iodine over the past century, and it also overcomes the disadvantages of iodine, such as low solubility, instability, easy hypersensitive reaction, thrill for skin and mucosa. Therefore, PVPI has become the first choice of Iodine disinfectants in the world's developed countries for nearly 30 years, and it has replaced Iodine tincture and other chlorine, mercury disinfectants.
The content of free iodine in PVPI is extremely small, and a great part of the Iodine is existed in the complex form. So the stablity of Iodine is greatly improved and the toxicity is greatly reduced.
PVPI has some characteristics as follows: the sterilization's spectrum is broad, the sterilization's speed is quick, no stimulation or allergic reaction, easy to soluble in water, the bactericidal action is long-lasting, no resistance to the drugs and long storage time .So it is recommended as the preferred medical iodine disinfectant by developedcountries for more than 30 years.Its major applications are in the field of prophylaxis:
-skin and mucous membrane antisepsis.
-surgical and hygienic hand disinfection.
Povidone Lodine Uses:
1. It has bactericidal effect like iodine. It can be used as disinfectant and bacteriostatic agent in the medicine for anti-septic purposes for eye drops, nasal drops, and cream agents. It can also be made into disinfectant.
2. It is mainly used for the skin disinfection and equipment disinfection in hospital surgery and injections as well as prevention of infection in the field of stomatology, gynecology, surgery, and dermatology; it can also be used for disinfection of household utensils and appliances; for food industry and aquaculture industry, it is used for disinfection and animal disease control. It is the preferred international and domestic choice of medical iodine-contained fungicides and disinfectants for epidemic prevention.
3. It is a kind of iodine carrier, the so-called “tamed iodine”. Because this product can gradually release iodine to exert an antibacterial effect; its mechanism of action is through causing the protein denaturation and further death of bacteria. It is effective in treating bacteria, fungi, as well as viruses with a relative small tissue irritation effect.
