Dosages and Administration of Injectable HGH

Growth hormone injections are made from recombinant human DNA, so they are an exact duplicate of the HGH normally produced by the pituitary gland. HGH injections are available in various dosages, depending on the condition they are being prescribed for. Prescription HGH is also known as somatropin. Injectable HGH is prescribed for men women and children with Growth Hormone Deficiency, or GHD. HGH injections may also be prescribed for the prevention of severe weight loss in people with AIDS, (muscle wasting) or to treat short bowel syndrome.

HGH injections are given subcutaneously, which means they are injected into the fatty tissue just below the surface of the skin. The most common injection sites are the thighs, abdomen, or buttocks.

Dosages and Administration of Injectable HGH

Your prescription for growth hormone injections will be tailored to best meet your particular goals and lifestyle. You will be carefully monitored over the course of your treatment with HGH, so any chance of side effects should be kept to a minimum.

Do I Need a Prescription for HGH Injections?

You cannot get HGH injections without a doctor’s prescription. Authentic dosages of HGH injections are only available with a prescription. There is no such thing as over-the-counter HGH, nor is genuine growth hormone therapy given in any other way than via injection. Any product claiming to be HGH that can purchased without a prescription, or is available in a pill, powder, or anything other than an injectable liquid, is not HGH. Any such product should be avoided. They can be hazardous.

A 2013 Report produced by the Partnership for a Drug-Free America found that more than 10% of teens in grades 9-12 had taken some form of illegal synthetic HGH at least once. There is no telling what it was these kids really were exposing themselves to. The majority of what teens buy online are mystery drug cocktails created in China, which may or may not contain an actual growth hormone, and who knows what other dangerous substances. Describing the report, Steve Pasierb, President of Partnership for Drug-Free Kids said, “It’s Russian Roulette. Are they taking a health risk with HGH or are they taking a health risk with some toxin?”

How Do I Get a Prescription for HGH Injections?

In order to obtain a prescription for HGH injections, you must present with the symptoms of GHD, have a physical exam, and a specific test for your ability to produce HGH. The most common way to test for your growth hormone level is to use an IGF-1 test.

How Do I Get a Prescription for HGH Injections?

Unlike a traditional blood test — which would merely screen for the presence of a particular hormone or biomarker in the blood — the insulin-like growth factor-1, or IGF-1 test, will tell your doctor if your pituitary gland responds correctly to a given stimulus, and is producing the amount of human growth hormone it should. If the results of the test, your exam, and your medical history, indicate GHD, you will be given a prescription for HGH injections.

What Is the Right Dosage of Injectable HGH?

HGH injections are given once or twice daily. The daily dosage of HGH varies by your age, weight and the condition it is being prescribed for. There are several manufacturers, or name brands, of prescription HGH injections available. They vary in their dosages and injection methods.
