GHRP-6

GHRP-6 is a small peptide, six amino acids long. It is the original version of this hunger-and-growth-hormone family.

Like GHRP-2, it copies ghrelin, your hunger hormone. It pushes your body to release a burst of growth hormone. So it is a GH secretagogue, meaning it makes you release your own growth hormone.

Its claim to fame is intense hunger. People often feel a strong urge to eat within minutes of a shot. It came out of lab work in the 1990s. There is almost no modern human data on it.

People use GHRP-6 to try to raise their own growth hormone for muscle, recovery, or fat loss.

But the real draw is the hunger. It produces a stronger appetite spike than GHRP-2. People on a bulk sometimes want exactly that.

It is older and less popular now, since cleaner options exist.

The proof is very thin. Thinner than GHRP-2, even.

It does release growth hormone, and it reliably triggers hunger. Those effects are real. But the evidence is just small pilot studies from the 1990s. There is no Phase 3 trial.

The hunger is so reliable that people sometimes use it just to prove the shot worked.

The same long-term worry applies: it raises IGF-1, which is a cancer concern over time. We have no long-term safety data. So this is a guess, built on very old science.

People take it as a small shot under the skin.

The typical research dose people mention is around 200 mcg. The half-life is short, about 15 to 30 minutes, so it does not stick around long.

This is what users report, not a recommendation. There is no approved dose because it is not an approved drug.

The common stuff

• A strong, fast hunger spike. Stronger than GHRP-2. For some people this is the point. For others it backfires.

The serious stuff

• It raises IGF-1, which is a long-term cancer concern. No long-term safety data exists.
• It is banned in sports by WADA. A tested athlete will fail.
• Avoid it if you have had cancer recently, or if you have a binge-eating history.
• Do not stack it on top of a GHRH-type peptide like CJC-1295 or sermorelin. That doubles the growth hormone signal and the IGF-1 rise, which stacks the cancer worry.

Talk to a real doctor before trying this. We are not your doctor.

Here are the ways people get it, safest to riskiest.

• Brand. Does not exist. There is no FDA-approved GHRP-6.
• Compounded. A few pharmacies make it with a prescription, around $100–$220 a month. Most clinics avoid it because of the hunger effect.
• Research-only (RUO). This is most of the supply. About $25–$70 a month.
• Gray market raw. The cheapest, $3–$10 a month. Banned in sports no matter the source.

If you buy research-grade, ask for a COA, a lab report on the vial. Make sure it lists molecular weight, since that is the only way to tell GHRP-6 (873) apart from GHRP-2 (817). They get swapped often.
