What is peptide Impurities?

What is peptide Impurities? By Somabiotech Co., Ltd Most of our customers often ask what other substances (impurities) are present in their peptide samples. This depends significantly on whether or not the sample was purified by reverse-phase HPLC. The following table summarizes the difference between the two cases. Impurities found in Non-Purified Peptides  Deletion sequences Truncation sequences Incompletely deprotected sequences Sequences modified during cleavage (reattachment of protecting groups at other locations on the peptide) DTT (dithiothreitol) TFA (trifluoroacetic acid) Acetic acid Peptides that have undergone side reactions such as proline isomerization or isoaspartimide formation, etc. (Note that the impurities are both peptides and non-peptides.) Impurities found in Purified Peptides Deletion sequences Truncation sequences Incompletely deprotected sequences Sequences modified during cleavage (reattachment of protecting groups at other locations on t

What is the difference between HGH and Steriods?

HGH, Somatotropin is a general growth-enhancing hormone. It will lead to basically everything growing. Overusing it means your bones, organs, everything will grow. Steroids, on the other hand, tend to attach to specific receptors, creating a suitable environment for protein synthesis. A stimulus will create a longer-lasting response, and a stimulus that is too heavy with low frequency will work better. For HGH, it binds to the HGH/Somatropin Receptor, which then facilitates IGF-1 excretion, resulting in growth in liver and muscles. It also works through EGF on bones and ibFGF on cartilage.

Is Human Growth Hormone safe?

Human Growth Hormone (HGH) is produced by the pituitary gland in order to stimulate cell regeneration and reproduction. The effects of HGH on the body can be generally described as anabolic, or building up, as in the building of bone density and muscle tissue. As we age, our growth hormone production declines. This can result in a condition known as Adult-Onset Growth Hormone Deficiency (AGHD) which can lead to a number of health problems. The effects of AGHD can vary depending on the level of deficiency and the age at which the deficiency occurs. According to research published in the Journal of Clinical Endocrinology, adults with AGHD  "…tend to have a relative increase in fat mass and a relative decrease in muscle mass and, in many instances, decreased energy and quality of life." Symptoms of Growth Hormone Deficiency: Low sex drive and impaired sexual function Fatigue, low energy, and loss of strength Decreased lean muscle Weight gain Decreased bone density Jo

HGH Side Effects, Results, Legality, and More

HGH Side Effects, Results, Legality, and More By  George Spellwin Dear Friend and Fellow Athlete, For decades, Human Growth Hormone (HGH) has been referred to as the "fountain of youth". It's been used by bodybuilders to cut fat, enhance steroid cycles, and recover from workouts faster. So it's easy to see why many look at HGH as some sort of wonder drug. But just exactly what is HGH? More importantly, what can it do for you, and is HGH safe to use? Keep reading this guide as you'll learn about HGH side effects, HGH results, is HGH legal, HGH vs steroids, and a step by step guide on how to mix HGH - complete with pictures. What is Human Growth Hormone? HGH  (a.k.a. somatropin or GH) is created by the pituitary gland, and its primary function is to help our bones, muscles, organs, and tissues properly grow during our early years. And it's important that, during childhood and teenage years, your HGH levels remain balanced so that you don'
