Side-by-Side Comparison

AspectHGH Fragment 176-191Thymosin Alpha-1
MechanismMimics 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 DosageTypical 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.
AdministrationSubcutaneous 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 EffectsGenerally 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.
