The design of laboratory is simple and exquisite, it’s equiped with the temperature control ventilation system, the water supply and the purified water supply, which satisfies the needs of environment request for each kind of experiments. Laboratory operation function and testing equipments: 1.Polypeptide synthesis. A successful synthesis of a polypeptide consists of different peptides or short peptides that are linked together by a polypeptide synthesizer to form the target polypeptide. For example, the GHRP-6 is composed of a peptide sequence HIS-D-TRP-ALA-TRP--D-PHE-LYS-NH2 in turn by a combination of links. 2.Bacteria ferment to obtain the target protein. The principle of bacterial fermentation is: Select the specific strains to be cultivated from the base of the strains library, and cultivate sufficient number of bacteria in the fermentation tanks with adequate water and temperature, and then collect and purify the target bacterial cells to obtain the protein raw material. 3.Polypeptide purification. Inject the dissolved polypeptide raw materials into the equipment called preparative liquid chromatograph. Machine will run according to the required purification time for different products for 0.5-2 hours, the product and impurities will be automatically separated in this process, the process will repeat 2-3 times until impurities is completely separated, to get our purified polypeptide raw materials. 4.Analysis and testing. Every batch of raw materials we produced will be tested by rigorous testing, such as HPLC, MS, endotoxin, microbial testing, moisture content, product content, and so on. These projects mainly done through the equipment High Performance Liquid Chromatography(HPLC), Matrix Assisted Laser Desorption Ionization Time of Flight Mass Spectrometry (MALDI-TOF-MS), Ion Chromatography, Moisture tester and other instruments. Our strict control on testing makes the product in line with the Chinese Pharmacopoeia standards, for example, the water content standard of product is less than 6%, the standard of the product content is greater than 80%, purity standard is more than 95% purity, bacterial endotoxin standard is less than 2.5eu/bottle, aseptic testing standard requires absolute aseptic.

    25 Dec 2018

    HGH Fragment 176-191 and  results. HGH fragment 176-191 is a valid treatment for obesity and much safer than conventional growth hormone. This substance,which is totally different of human growth hormone, doesn’t have any negative effect on insulin sensitivity. HGH Fragment is capable to control fat metabolism with no expense or bad effects on insulin sensitivity.The existence of HGH revoke the formation of fatty acids and lipids,which means that there is a fat burning component  responsible for the same. Although it burns lipids and fats,the users are truly believed that they do not feel any hunger suppressing qualities of any unnecessary side effects connected to the burning compound like the ephedrine. Scientific studies shows that Fragment 176-191 won’t lead to hyperglycemia cause it don’t have solve any problems  and it doesn’t compete for HGH receptors. At times, HGH will help you get several benefits such as lean body mass, protein synthesis, increase bone mineral density, and better sleeping patterns. HGH Frag 176-191 will not only assure you with a lean body but also strengthen your bones and muscle tissues that will benefit or assist you to improve the functions of your vital organs. It doesn’t influence your glucose contents so it wouldn’t be effective of your glucose sensitivity.

  • How much muscle will I put on by using Human Growth Hormone(Somatropin)?
    How much muscle will I put on by using Human Growth Hormone(Somatropin)?

    13 Nov 2018

    How much muscle will I put on by using Human Growth Hormone(Somatropin)? The effects of Somatropin reflects to different body conditions and results depend on many factors.  20% – 30% of lean muscle during a 4-5 months long HGH therapy if it's done in optimal conditions. The results become noticeable after about 2 months of use. The amount of muscle gained by using HGH depends on many factors including one’s daily physical strain (workout), genetics, diet, age, quality and quantity of sleep, lifestyle, previous usage of steroids or HGH, etc. With an estimate of an overall healthy first time HGH user who is in good shape, works out 3-5 times per week, sleeps at least 7 hours per night and eats a protein rich diet can expect to gain between 20 – 30 percent of muscle mass within 4-5 months. Or if I put it differently – at the dose of 4IU per day, growth hormone will help an already active individual push past his previous muscle building limit by 20% to 30%. Results from the first HGH cycle are always the most drastic – no subsequent cycle will match the success of the initial one. This might be because: In initial cycle the body is surprised by the high levels of HGH (and consequently IGF-1). By the time it develops the ability to control such levels of HGH/IGF, the muscle ceiling has already expanded by 20% – 30%. After the initial HGH cycle (or steroid use) the muscle growth “ceiling” is already pretty high. The body is designed to retain just enough muscle as is needed for the person’s daily work routines. Excess muscle is gradually removed. An active individual using growth hormone to build muscle eventually reaches his “muscle ceiling” (his personal best) during every HGH cycle, but to him the result might not feel that impressive after the first time – he has seen it before.
