TB-500 vs CJC-1295
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
TB-500
Thymosin Beta-4 (TB-500) is a naturally occurring peptide present in almost all human and animal cells. It plays a crucial role in tissue repair and regeneration.
Full details →CJC-1295
CJC-1295 is a synthetic analog of growth hormone-releasing hormone (GHRH) that stimulates the pituitary gland to produce more growth hormone.

| Aspect | TB-500 | CJC-1295 |
|---|---|---|
| Mechanism | TB-500 promotes cell migration and differentiation, regulates actin (a cell-building protein), and reduces inflammation. It supports the formation of new blood vessels and wound healing. | CJC-1295 binds to GHRH receptors in the pituitary, triggering increased production and release of growth hormone. The DAC (Drug Affinity Complex) version extends half-life significantly. |
| Typical Dosage | Research protocols typically use 2-2.5mg twice weekly during the loading phase, followed by maintenance dosing of 2mg every 2 weeks. | CJC-1295 DAC: 1-2mg weekly. CJC-1295 no DAC (Mod GRF 1-29): 100-300mcg 2-3 times daily. |
| Administration | Administered via subcutaneous or intramuscular injection. Some protocols suggest injection near injury sites. | Subcutaneous injection, often combined with a GHRP like Ipamorelin for synergistic effects. Best administered before sleep or fasted. |
| Side Effects | May cause temporary fatigue, headache, or localized irritation at injection sites. | Water retention, tingling in extremities, potential increase in cortisol and prolactin levels. |
