GHRH 5mg Overview

GHRH 5mg from Peptide Science is the synthetic 44-amino-acid full-length native human growth-hormone-releasing hormone (also known as somatocrinin or somatoliberin), supplied as a lyophilised vial for in-vitro pituitary research. The compound is the unmodified native sequence, distinct from the stability-enhanced analogs Sermorelin (truncated 1-29) and Tesamorelin (44-residue with N-terminal trans-3-hexenoyl group).

Compound Class and Mechanism

GHRH 1-44 is the native hypothalamic peptide released from the arcuate nucleus that binds the GHRH receptor on pituitary somatotrophs and triggers growth-hormone synthesis and release through the adenylate cyclase / cAMP / PKA signalling cascade. The native unmodified form is short-acting in cell-culture conditions due to DPP-IV enzymatic cleavage at the position 2 to 3 peptide bond, which is the structural basis for the half-life-extending modifications in the Sermorelin (truncation) and Tesamorelin (trans-3-hexenoyl modification) analogs.

Specifications

For the truncated 29-residue Sermorelin format and the stabilised Tesamorelin format, see Sermorelin 5mg and Tesamorelin 5mg.

Reconstitution and Handling

The lyophilised vial reconstitutes with bacteriostatic water at the working concentration set by the principal investigator. Aliquoting reconstituted stock for single-use frozen storage is the standard preclinical handling practice for short-sequence peptides.

Quality and Shipping

Each batch passes HPLC at greater than 99 percent purity, with mass-spectrometry identity confirmation. A Certificate of Analysis accompanies every order. Material is filled in a US laboratory under ISO 9001:2015-aligned quality systems and dispatched in temperature-monitored insulated packaging.
