TRH Thyrotropin (Protirelin) (25mg)

$90.00

TRH (Thyrotropin Releasing Hormone), also known as Protirelin, is a hypothalamic tri-peptide that serves as a master regulator of the thyroid axis. Research focuses on its ability to stimulate the release of TSH and Prolactin, its potential as a rapid mood modulator, and its role in autonomic regulation and arousal.

Form: Lyophilized Powder
Primary Action: TRH-1 & TRH-2 Receptor Agonist
Research Focus: Thyroid disorders, clinical depression models, and circadian rhythm.

TRH (Protirelin) is a naturally occurring tri-peptide synthesized in the hypothalamus. While its primary biological role is to signal the anterior pituitary to produce Thyroid Stimulating Hormone (TSH), its receptors are widely distributed throughout the central nervous system, making it a versatile tool for studying neuro-endocrine signaling and behavioral science.

Key Research Areas:

Pituitary & Thyroid Axis: TRH is the fundamental trigger for TSH production, which subsequently stimulates the thyroid gland to release T3 and T4. Researchers use Protirelin to evaluate anterior pituitary function and the underlying mechanisms of thyroid-related metabolic disorders.
Mood & Depression Models: TRH is being actively studied for its rapid-acting neuro-modulatory effects. In spinal administration studies, researchers observed a 50% or greater reduction in depressive markers, suggesting that TRH may act as a positive modulator of mood independent of its hormonal functions.
Circadian Rhythm & Sleep: Because TRH production follows a natural cycle, studies have explored the impact of nocturnal exposure. Findings suggest that timing the introduction of TRH to match circadian rhythms may enhance its efficacy in mood disorder research.
TREK-1 Channel & Autonomic Function: Preliminary data indicates TRH may influence the TREK-1 potassium channel, impacting arousal, feeding behaviors, and autonomic regulation. It is also investigated for its potential to mitigate free radical damage in various cell types.
BBB Permeability Research: As a small peptide, TRH serves as a model for studying blood-brain barrier (BBB) transport, with ongoing investigations into how to optimize delivery to target CNS receptors.

Elite Peptide Supply provides high-purity TRH (Protirelin) for laboratory use. Our peptide is synthesized to ensure the Pyr-His-Pro sequence remains highly stable for accurate mapping of thyroid and neurological pathways.
