Ipamorelin vs Thymosin Alpha-1
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
Ipamorelin
Ipamorelin is a selective growth hormone secretagogue that stimulates the release of growth hormone from the pituitary gland without significantly affecting cortisol or prolactin.
Full details →Thymosin Alpha-1
Thymosin Alpha-1 is a peptide naturally produced by the thymus gland that plays a crucial role in immune system modulation. It is approved in over 35 countries for various conditions including hepatitis B and C.

| Aspect | Ipamorelin | Thymosin Alpha-1 |
|---|---|---|
| Mechanism | Acts as a ghrelin mimetic, binding to the ghrelin receptor (GHS-R) in the pituitary to stimulate GH release. Highly selective with minimal effect on other hormones. | 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 ranges from 200-300mcg administered 2-3 times daily, often combined with CJC-1295. | 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 administered fasted or before sleep. Often stacked with GHRH peptides. | Subcutaneous injection. Often used in cycles or as part of comprehensive immune support protocols. |
| Side Effects | Generally well-tolerated. May cause mild headaches, lightheadedness, or increased hunger initially. | Generally well-tolerated. Rare side effects include injection site reactions, mild flu-like symptoms, and temporary fatigue. |
