A modified fragment of human growth hormone (amino acids 177-191) originally developed as an anti-obesity agent. Targets fat metabolism without the growth-promoting effects of full HGH.
A synthetic analog of growth hormone-releasing hormone (GHRH) that stimulates the pituitary gland to produce more growth hormone. Available with or without a Drug Affinity Complex (DAC) that extends its half-life.
Stimulates lipolysis (fat breakdown) and inhibits lipogenesis (fat formation) by mimicking the fat-reducing action of natural growth hormone without affecting blood sugar or tissue growth.
Binds to GHRH receptors on the pituitary gland, stimulating pulsatile release of growth hormone. The DAC version binds to albumin in the blood, extending the half-life from minutes to approximately 6-8 days.
