Human growth hormone as is used in the injections is not measured in nanograms (ng), it is measured in IU (international units) or mg (milligrams). Some sellers use what we call the "nanogram scam" to try to mislead customers into thinking their product contains a larger amount of human growth hormone than other products, which is not true.
Also, any product that gives the amount of HGH in their product in nanograms is not an FDA registered product because the FDA does not allow the use of milligrams, grams, etc., because it is not the proper form of measurement for homeopathic products. Proper FDA registered homeopathic products like ours will give the amount of each ingredient in potencies such as "X" and "C" (see the previous question). The HGH Nanogram scam.
