TRH Thyrotropin 20 mg (also known as Protirelin) is a synthetic analog of thyrotropin-releasing hormone (TRH), a tripeptide produced by the hypothalamus. Supplied by Peptide Sciences USA in a research-grade 20 mg vial, this peptide is studied for its role in regulating the hypothalamic-pituitary-thyroid (HPT) axis and influencing neurotransmitter activity. It serves as a critical component in research exploring thyroid function, endocrine feedback loops, and CNS signaling.
Mechanism of Action
TRH acts by binding to TRH receptors in the anterior pituitary, triggering the release of thyroid-stimulating hormone (TSH), which in turn stimulates the thyroid gland to produce T3 and T4 hormones. This cascade is vital in maintaining metabolic homeostasis, thermoregulation, and cardiovascular balance. In research models, TRH administration leads to increased circulating TSH and thyroid hormone levels, useful in evaluating pituitary responsiveness and endocrine function.
Beyond the HPT axis, TRH exhibits neuromodulatory effects in the central nervous system. It has been shown to influence arousal, mood regulation, and motor function. Some studies suggest potential roles in neuroprotection, seizure modulation, and even reversal of opioid-induced respiratory depression. These wide-ranging actions make TRH an attractive subject in both endocrinological and neurological research domains.
Key Features & Benefits

Frequently Asked Questions
Thyrotropin, also known as thyroid-stimulating hormone (TSH), regulates the production of thyroid hormones (T3 and T4) by stimulating the thyroid gland in response to TRH signals from the hypothalamus.
TRH Thyrotropin (Protirelin) is a synthetic form of thyrotropin-releasing hormone used in research to evaluate pituitary and thyroid axis function and explore neuroendocrine activity.
In primary hypothyroidism, TRH levels are typically elevated due to reduced negative feedback from low thyroid hormone levels. This causes increased TSH secretion in an attempt to stimulate the thyroid.
