GHRP-6

GHRP-6 is a synthetic peptide known as Growth Hormone-Releasing Peptide 6. It is a growth hormone secretagogue, meaning it stimulates the body to produce and release its own growth hormone (GH), unlike human growth hormone (HGH) which is an exogenous hormone. GHRP-6 works by acting as a mimic of the hormone ghrelin, often called the "hunger hormone," and binding to the ghrelin receptor in the pituitary gland and hypothalamus. This action leads to a pulsatile release of GH.

Benefits and Side Effects

GHRP-6 has been explored for various potential benefits, particularly in a research context. Some of the reported benefits include:

• Increased muscle mass and strength: By elevating GH and IGF-1 levels, it can promote protein synthesis and muscle growth.

• Fat loss: It can increase the metabolism of fat cells, leading to a reduction in body fat.

• Improved recovery and healing: Enhanced GH levels can speed up recovery from injuries and training, and promote collagen synthesis for better joint and skin health.

• Increased appetite: Mimicking ghrelin, it can stimulate hunger, which is beneficial for those who have trouble consuming enough calories for muscle gain.

• Better sleep: GH is crucial for deep sleep cycles, and GHRP-6 can enhance this, leading to more restorative rest.

Potential side effects, which are often related to its ghrelin-mimicking properties, can include:

• Increased hunger: This is the most common side effect and can be difficult to manage.

• Water retention and bloating: Elevated GH and IGF-1 levels can cause mild fluid retention.

• Fatigue or lethargy.

• Carpal tunnel-like symptoms.

• Elevated prolactin and cortisol levels: It has been shown to increase levels of these hormones, which can have various downstream effects.

Dosage and Half-Life

There is no universally accepted clinical dosage for GHRP-6, but research studies and anecdotal usage often point to a dosage of 100 mcg per injection, administered 2 to 3 times per day. The injections are typically subcutaneous (under the skin) and should be taken on an empty stomach to maximize the GH release, as high blood glucose levels can blunt its effect.

The half-life of GHRP-6 is relatively short, approximately 2.5 hours. This is why it needs to be injected multiple times a day to maintain elevated GH levels. The detection time in a doping test is also quite short. The parent compound is typically detectable in urine for up to 23 hours, and its metabolites are detectable for up to 12 hours.

Effects on Other Hormones and Ratios

• Prolactin: GHRP-6 can cause a slight increase in prolactin levels.

• Progesterone and Estrogen: There is no significant evidence that GHRP-6 directly impacts progesterone or estrogen levels. Its primary action is on the GH/IGF-1 axis and ghrelin receptors.

• Sterogenic/Androgenic Ratio: GHRP-6 is not a steroid and therefore does not have a measurable anabolic or androgenic ratio like anabolic-androgenic steroids (AAS). The anabolic effects of GHRP-6 are mediated through the GH/IGF-1 axis, which is a different pathway from androgen receptors.
