HGH Fragment 176-191 vs Thymosin Alpha-1
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
HGH Fragment 176-191
HGH Fragment 176-191 is the fat-reducing portion of the growth hormone molecule. Unlike AOD-9604 (which has an additional tyrosine), this is the exact fragment of HGH responsible for lipolytic effects.

| Aspect | HGH Fragment 176-191 | Thymosin Alpha-1 |
|---|---|---|
| Mechanism | Mimics the lipolytic region of growth hormone, stimulating fat breakdown and inhibiting lipogenesis without affecting blood sugar or promoting growth. Works independently of GH receptors. | Enhances T-cell function and maturation, stimulates dendritic cell activity, and modulates cytokine production. Promotes the differentiation of stem cells into mature T lymphocytes. |
| Typical Dosage | Typical dosing: 250-500mcg daily, often split into 2-3 doses. Usually administered on empty stomach, often with fasted cardio. | Clinical dosing typically ranges from 1.6mg to 6.4mg administered subcutaneously 2-3 times weekly. Research protocols may vary. |
| Administration | Subcutaneous injection. Best results when used fasted and combined with exercise. Avoid eating for 30 minutes post-injection. | Subcutaneous injection. Often used in cycles or as part of comprehensive immune support protocols. |
| Side Effects | Generally well-tolerated. May cause injection site irritation, temporary lethargy, or headache. Does not affect blood glucose significantly. | Generally well-tolerated. Rare side effects include injection site reactions, mild flu-like symptoms, and temporary fatigue. |
