HGH Fragment 176-191 is a spliced variant of native human growth hormone. Specifically, it is made of the last 16 amino acids on GH’s long 191 amino acid sequence. This fragment seems to retain some (not all) of the biological activity of growth hormone. On the one hand, the compound is no longer able to bind with the cellular GH receptor. As such, it does not elevate serum IGF-1, nor appear to have anabolic effects. On the other, it may still have distinct lipolytic (fat loss) properties. A drug like this could be applicable in situations where fat loss is desired, but GH’s wider spectrum of anabolic effects (and potential side effects) is not. In the fitness community, this substance is used exclusively for fat loss.

Side Effects

The most common side effects to HGH Fragment 176-191 include sleepiness and lethargy. Injection site reactions are also highly prominent (See below). Otherwise, the safety and adverse reaction profile of this drug are not fully characterized at this time.

The subcutaneous administration of this drug may cause redness, itching, pain, and/or lumps at the site of injection.

Administration

HGH Fragment 176-191 is generally given via subcutaneous (SC) injection.

When used for physique-enhancing purposes, HGH Fragment 176-191 is usually administered at a dosage of 0.25 to .5 mg (250-500 meg) per injection. This may be given 1-2 times daily, usually on an empty stomach. One dosing episode is typically 30-60 minutes before cardio training, which may further intensify its fat loss effects. Total daily dosage generally does not exceed 1,000 meg.

Cycles of HGH Fragment 176-191 usually last 2-3 months, though longer programs are not uncommon.
