Triptorelin- Summary
- ARA-290 is a synthetic 11-amino acid peptide derived from the helix B region of erythropoietin (EPO). Unlike EPO, it selectively activates the innate repair receptor (IRR) without stimulating hematopoiesis, providing tissue protection, anti-inflammation, and neuropathy relief.
- Triptorelin is a synthetic decapeptide analog of gonadotropin-releasing hormone (GnRH) with 100x the potency of native GnRH. An FDA-approved drug (Trelstar) for prostate cancer and precocious puberty, it is also used in post-cycle therapy (PCT) to rapidly restart the hypothalamic-pituitary-gonadal (HPG) axis after anabolic steroid suppression.
