|---|---|---|---|
| Goal fit | Fat Loss & Metabolism, GH Axis Optimization | Muscle Growth & Strength, Fat Loss & Metabolism, GH Axis Optimization | GH Axis Optimization |
| What users compare it for | Visceral fat reduction in HIV lipodystrophy (evidence-backed). General weight loss claims are limited. | 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 timeline | Clinical endpoints assessed at 26 weeks in pivotal studies. | 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 tradeoff | 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. | Evidence is stronger than most compounds in this category, but route, side effects, and vendor fit still matter. |
03 · Safety & restrictions
| Decision factor | Tesamorelin | CJC-1295 | Sermorelin |
|---|---|---|---|
| Adverse effects | Increased neoplasm risk, elevated IGF-1, fluid retention, glucose intolerance/diabetes, hypersensitivity. | Injection-site reactions, headache, diarrhea, flushing, transient hypotension at higher doses. | Glucose intolerance risk; theoretical neoplasia concerns with sustained IGF-1 elevation. |
| Contraindications | Active malignancy, pregnancy, pituitary gland disorders (per label). | GH-axis stimulation risks: glucose intolerance, theoretical neoplasia concerns with elevated IGF-1. | Active malignancy (by analogy to tesamorelin class warnings). |
| Interaction notes | CYP450-metabolized drugs; glucocorticoid replacement requirements may be affected. | 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. |
| Regulatory status | Prescription-approved | Not approved | Not approved |
| FDA flag | No current flag noted | FDA compounding caution | FDA status unclear |
