Hexarelin side effects and risks

Reported side effects

• Cortisol and prolactin increases: In acute IV tests, prolactin rose up to about 180% and cortisol about 40%; these are changes, not incidence rates., moderate (source)
• Weaker GH response with repeated use: GH AUC fell from 19.1 to 10.5 mcg/L·hour by week 16; recovered after four weeks off., mild (source)
• Reduced deep sleep: Observed in a seven person nighttime experiment; event rate not reported., moderate (source)
• Blood pressure changes: unknown, moderate (source)
• Swelling, joint discomfort or glucose changes: unknown, moderate (source)
• Immune reaction or injection infection: unknown, serious (source)

Stop and get help if

• Trouble breathing, tongue swelling, fainting or widespread hives: Stop and get emergency care now.
• Sudden severe headache, new vision loss or repeated vomiting: Get emergency assessment now; a pituitary or pressure problem must be excluded.
• Chest pain, severe breathlessness or collapse: Call emergency services now.
• Persistent severe abdominal pain or repeated vomiting: Stop and get urgent medical assessment.
• Confusion, seizure, or low blood sugar that does not resolve: Get emergency help now; do not drive.
• Fever with a hot, spreading, painful injection site: Get urgent care for a possible injection infection.

Who should avoid it

• pregnant: Avoid during pregnancy. Reproductive safety is unstudied; this screen is precautionary.
• breastfeeding: Avoid while breastfeeding. Human infant exposure and safety are unknown.
• tryingToConceive: Avoid while trying to conceive. Human fertility and early-pregnancy safety are unknown.
• under18: Historical child studies do not support unsupervised use in minors.
• activeCancer: GH and IGF-1 are growth signals. Avoid with active cancer; this applies GH-treatment precautions to secretagogues.
• cancerHistory: Prior cancer needs a clinician review before raising GH or IGF-1. Recurrence risk with this compound is unknown.
• diabetes: GH-related changes can worsen insulin sensitivity. Review blood sugar control and medicines.
• heartCondition: Fluid retention may strain the heart. Heart-disease safety is not established for home-use schedules.
• uncontrolledBloodPressure: Review uncontrolled blood pressure before use. Fluid retention and pressure changes need assessment.
• kidneyDisease: Kidney-disease dose adjustments and repeated-dose safety are not established.
• liverDisease: Liver-disease dose adjustments and repeated-dose safety are not established.
• diabeticRetinopathy: Review proliferative eye disease before raising GH or IGF-1. This is a GH-class precaution.
• pancreatitisHistory: Review prior pancreatitis. GH-class safety concerns do not establish a risk rate for this compound.
• sleepApnea: Review sleep apnea and new swelling. GH-related tissue or fluid changes are a class concern.
• surgeryPlanned: Tell the surgical team about use and all stacks. Perioperative safety depends on the specific study setting.
• testedAthlete: WADA bans this compound at all times, including out of competition.
• other: Do not add a GH secretagogue when GH or IGF-1 is already excessive. Investigate the cause.
• other: A pituitary mass needs specialist review. GH testing and GH-raising drugs are not interchangeable.

Interactions

• Insulin and sulfonylureas: GH-class precaution: insulin sensitivity and medicine needs can change. Exact interaction trials for this peptide are lacking.
• Other GH secretagogues, GH, and IGF-1: Overlapping GH/IGF-1 effects can add hormone, swelling and blood sugar risks. Combination benefit is not established.
• Glucocorticoids and oral estrogen: These can change GH responses or IGF-1 interpretation. Do not change prescribed hormone replacement to alter a peptide response.
• Anticoagulants and antiplatelets: General injection precaution: blood thinners increase bleeding/bruising risk. A direct interaction with this peptide has not been established.

Product quality risks

• Unregulated products may have the wrong identity, dose or sterility. A purity percentage alone cannot establish injection safety.
• Related GHRPs had altered identities in seized products. No hexarelin-specific market survey was found.
• No representative market-wide contamination or underdosing rate was found for this compound.

How Hexarelin works

It turns on the ghrelin receptor, which helps the pituitary release growth hormone. GH can then raise IGF-1, a growth signal. A larger hormone pulse does not prove better strength, recovery or longer life.

• GHS-R1a, the ghrelin receptor: Prompts GH release through the brain and pituitary.
• GH / IGF-1 pathway: Can increase growth signals; lasting benefits depend on the compound and schedule.

Half-life: No confirmed human plasma half-life of the peptide itself was found; a reported 55 minutes describes the GH response.
