Sermorelin – 5mg

Sermorelin is a synthetic analogue of growth hormone releasing hormone (GHRH) consisting of the first 29 amino acids of the native 44 amino acid GHRH sequence. The biologically active fragment that retains full GHRH receptor binding and GH secretory stimulation activity. iLab Pharma’s formulation supplies 5mg as a lyophilized vial, preserving peptide structural integrity and potency across storage conditions until reconstitution. A standard practice for GHRH analogues where aqueous stability at ambient temperature is limited and lyophilized storage maintains compound activity across extended research timelines.

Sermorelin’s mechanism of action operates through selective GHRH receptor binding in the anterior pituitary, stimulating endogenous growth hormone secretion in a physiologically regulated pulsatile pattern. This pituitary stimulating mechanism preserves the natural feedback regulation of the GH/IGF-1 axis, somatostatin mediated suppression continues to regulate GH pulse amplitude, preventing the continuous GH elevation associated with exogenous GH administration. Sermorelin is the shortest GHRH analogue in active research use, and its truncated 29 amino acid sequence produces a shorter half-life than longer acting GHRH analogues like CJC-1295 and Tesamorelin, requiring more frequent administration to maintain sustained pituitary GHRH receptor stimulation but offering faster clearance and a more adjustable activity profile suited to short duration research protocols.

CSD stocks three distinct GHRH receptor agonists Sermorelin, Tesamorelin, and CJC-1295. Each offering different half-life profiles and clinical research backgrounds for comparative GHRH axis stimulation research. Sermorelin’s 29 amino acid truncated sequence and shorter half-life position it as the most rapidly clearing GHRH analogue in the range, Tesamorelin’s trans 3 hexenoic acid stabilization produces an intermediate profile with FDA approval backing its clinical literature, and CJC-1295’s DAC modification produces the longest active window among the three. Researchers examining GHRH receptor stimulation across different duration profiles can source all three from a single verified Canadian supplier.

iLab Pharma formulations are stocked by Canada Steroid Depot following the same rigorous third party lab verification process applied to every product in our range. Each batch is tested for concentration accuracy and purity before being made available, with COA documentation available on request. CSD’s sourcing standards apply uniformly across all manufacturers we carry, and iLab Pharma’s Sermorelin meets those standards consistently. All orders ship discreetly across Canada in plain, unmarked packaging with no identifying information on the exterior.

Reconstitute with bacteriostatic water prior to use. Store lyophilized peptide at 2–8°C away from direct light. Once reconstituted refrigerate and use within 28 days. Intended for research purposes only.
