What users compare it forGH-axis modulation; sleep architecture research interest.Sustained GH and IGF-1 elevation; body composition modulation (long-horizon, not well-established for consumer outcomes).GH axis stimulation; growth/body composition changes over months.
Onset timelineAcute endocrine effects; sleep effects studied overnight.Biomarker effects persist multiple days; IGF-1 elevations up to ~2 weeks after single dose.GH secretion changes occur acutely; body composition endpoints are months-horizon.
Main tradeoffPotential upside comes with much more safety and screening caution than lower-risk alternatives.Evidence is stronger than most compounds in this category, but route, side effects, and vendor fit still matter.Evidence is stronger than most compounds in this category, but route, side effects, and vendor fit still matter.

03 · Safety & restrictions

Decision factorHexarelinCJC-1295Sermorelin
Adverse effectsEndocrine spillover (ACTH, cortisol, prolactin).Injection-site reactions, headache, diarrhea, flushing, transient hypotension at higher doses.Glucose intolerance risk; theoretical neoplasia concerns with sustained IGF-1 elevation.
ContraindicationsNo formal label.GH-axis stimulation risks: glucose intolerance, theoretical neoplasia concerns with elevated IGF-1.Active malignancy (by analogy to tesamorelin class warnings).
Interaction notesUnknown; caution with other GH-axis compounds.Monitor insulin/glucose sensitivity, thyroid axis, and cortisol/prolactin. Trials report no significant cortisol/prolactin/TSH/LH increases at 60 µg/kg single dose.Unknown interaction profile outside supervised settings.
