What users compare it forModerate weight loss, improved satiety, and HbA1c reduction in clinical populations.Sustained GH and IGF-1 elevation; body composition modulation (long-horizon, not well-established for consumer outcomes).Visceral fat reduction in HIV lipodystrophy (evidence-backed). General weight loss claims are limited.
Onset timelineMetabolic and appetite effects begin within days to weeks; body-weight effects build over months.Biomarker effects persist multiple days; IGF-1 elevations up to ~2 weeks after single dose.Clinical endpoints assessed at 26 weeks in pivotal studies.

03 · Safety & restrictions

Decision factorLiraglutideCJC-1295Tesamorelin
Adverse effectsGI effects are common, especially nausea, vomiting, constipation, and diarrhea. Pancreatitis and gallbladder events remain class concerns.Injection-site reactions, headache, diarrhea, flushing, transient hypotension at higher doses.Increased neoplasm risk, elevated IGF-1, fluid retention, glucose intolerance/diabetes, hypersensitivity.
ContraindicationsAvoid in personal or family history of medullary thyroid carcinoma or MEN2. Use caution with pancreatitis history and pregnancy.GH-axis stimulation risks: glucose intolerance, theoretical neoplasia concerns with elevated IGF-1.Active malignancy, pregnancy, pituitary gland disorders (per label).
Interaction notesSame class cautions as other GLP-1 agents: hypoglycemia risk rises with insulin or sulfonylureas, and gastric emptying delay can affect oral medications.Monitor insulin/glucose sensitivity, thyroid axis, and cortisol/prolactin. Trials report no significant cortisol/prolactin/TSH/LH increases at 60 µg/kg single dose.CYP450-metabolized drugs; glucocorticoid replacement requirements may be affected.
