Core Molecular Specs & Technical Index
Sermorelin, also known as GRF (1-29) amide, is a synthetic analog of the human growth hormone-releasing hormone (GHRH). It consists of a 29-amino acid peptide chain that specifically targets the pituitary gland to stimulate the endogenous release of growth hormone. For B2B buyers, understanding the precise molecular specifications is the first step in evaluating sermorelin peptide benefits for cosmetic formulations and laboratory research.
- Molecular Formula: C₁₄₉H₂₄₆N₄₄O₄₂S, with a molecular weight of approximately 3357.8 Da, ensuring high specificity for GHRH receptors.
- Purity Grade: Standard industrial grade is ≥98% by HPLC, with premium research grade reaching ≥99.5% for maximum bioactivity and minimal impurity interference.
- Solubility Profile: Highly soluble in sterile water for injection (WFI) and phosphate-buffered saline (PBS) at concentrations up to 10 mg/mL, with optimal stability at pH 4.5–5.5.
- Storage Requirements: Lyophilized powder must be stored at -20°C or below, protected from light and moisture. Reconstituted solutions remain stable for 14 days at 2–8°C.
- Appearance & Form: White to off-white lyophilized powder, free from visible particulates, supplied in sterile, depyrogenated vials with rubber stoppers and aluminum seals.
Industry data from the Peptide Therapeutics Foundation indicates that peptides with purity above 99% demonstrate a 40% higher receptor binding affinity compared to those at 95% purity, directly correlating with enhanced efficacy in research applications.
Manufacturing & Quality Control
The production of high-purity sermorelin involves a multi-step solid-phase peptide synthesis (SPPS) process, followed by rigorous purification and analytical validation. Each batch must meet strict quality control standards to ensure consistent sermorelin peptide benefits for downstream users.
Production Process
Starting with Fmoc-protected amino acids, the peptide chain is assembled on a resin support using automated synthesizers. After cleavage and deprotection, the crude peptide undergoes preparative reverse-phase high-performance liquid chromatography (RP-HPLC) to achieve target purity levels. The final product is lyophilized under sterile conditions and sealed in vacuum vials.
Quality Control Measures
- HPLC Analysis: Every batch is tested for purity using a validated C18 column method with UV detection at 214 nm and 280 nm.
- Mass Spectrometry: ESI-MS or MALDI-TOF confirms molecular weight within ±0.5 Da of the theoretical value.
- Endotoxin Testing: LAL assay ensures endotoxin levels below 0.5 EU/mg for safe laboratory handling.
- Residual Solvents: GC analysis verifies that solvents like acetonitrile and TFA are below ICH Q3C limits.
- Stability Studies: Accelerated stability testing at 40°C/75% RH for 4 weeks predicts shelf life of 24 months at -20°C.
Certifications
- ISO 9001:2015 certified manufacturing facility
- GMP compliance for peptide synthesis
- Certificate of Analysis (CoA) provided with each batch
- Third-party testing by independent laboratories (e.g., SGS, Eurofins)

Commercial Application Scenarios
Understanding the practical applications of sermorelin helps B2B buyers align product specifications with end-use requirements. The sermorelin peptide benefits extend across multiple commercial channels.
Cosmetic Formulation
In anti-aging skincare, sermorelin is incorporated into serums and creams at concentrations of 0.1–1.0% to support collagen synthesis and skin firmness. Formulators value its stability in oil-in-water emulsions when combined with antioxidants like vitamin C and E. The peptide’s ability to stimulate endogenous growth hormone release makes it a key ingredient in premium cosmeceutical lines targeting mature skin.
Laboratory Research
Research institutions use sermorelin for in vitro studies on pituitary cell function, growth hormone regulation, and cellular senescence. It is also employed in animal models to investigate metabolic pathways and aging processes. High-purity grades are essential for reproducible results in academic and pharmaceutical R&D.
Bulk Wholesale Usage
Distributors and contract manufacturers purchase sermorelin in bulk quantities (1–100 grams) for resale or incorporation into finished products. Bulk buyers prioritize consistent batch-to-batch quality, competitive pricing, and reliable supply chains. The sermorelin peptide benefits in this context include cost efficiency and formulation flexibility.

Bulk Purchase Selection Guide
When sourcing sermorelin for commercial use, B2B buyers must navigate common pitfalls to ensure they receive genuine sermorelin peptide benefits. This guide outlines key selection criteria.
Common Pitfalls
- Mislabeled Purity: Some suppliers claim 99% purity but deliver material with significant impurities. Always request a CoA with HPLC chromatogram.
- Inadequate Storage: Peptides shipped without cold chain packaging degrade rapidly. Verify that the supplier uses insulated containers with ice packs or dry ice.
- Lack of Traceability: Without batch numbers and manufacturing dates, quality issues cannot be traced. Choose suppliers with full lot tracking.
Selection Standards
- Request third-party test reports from accredited labs.
- Confirm that the peptide is manufactured in a GMP-compliant facility.
- Check for residual solvent and heavy metal analysis.
- Evaluate the supplier’s lead time and minimum order quantity (MOQ).
- Ask for references from other B2B clients in your industry.

Frequently Asked Questions
Q1: What is the typical purity range for sermorelin used in cosmetic formulations?
For cosmetic applications, a purity of ≥98% is generally acceptable, but premium brands often require ≥99% to ensure product consistency and minimize potential irritants. Always request a CoA to verify the actual purity level.
Q2: How should sermorelin be stored after reconstitution for laboratory use?
Reconstituted sermorelin should be stored at 2–8°C and used within 14 days. For longer storage, aliquot the solution and freeze at -20°C, avoiding repeated freeze-thaw cycles to maintain bioactivity.
Q3: Can sermorelin be combined with other peptides in a single formulation?
Yes, sermorelin is compatible with many peptides, such as GHRP-2 or ipamorelin, in research settings. However, compatibility testing is recommended to avoid precipitation or degradation. Always consult a formulation specialist for specific combinations.
