Verified batches tested via RP-HPLC and ESI-MS with comprehensive analytical release dossiers for clinical pipelines and commercial supply.
Sermorelin Acetate (GRF 1-29 amide) is a synthetic 29-amino acid polypeptide stimulating pituitary growth hormone secretion. Meeting global pharmacopeial standards requires precise control over synthesis kinetics, stereoisomer formation, and trace impurity profiles.
Utilizing high-loading CTC resin and Fmoc/tBu orthogonal protection strategies. Sequential coupling is automated to suppress racemization of sterically hindered amino acids (Arg, Leu, and Lys residues), guaranteeing single-chain peptide sequence fidelity over 99.0%.
Two-step orthogonal reverse-phase liquid chromatography combining C18 and C8 silica matrices. Effectively eliminates critical related substances including [D-Arg]-sermorelin, oxidized Met27, and des-amino truncated species, pushing individual impurities to < 0.1%.
Formulated with medical-grade mannitol excipient under Grade A laminar air flow. Cycle parameters are adjusted through automated shelf freeze-drying to maintain Cake integrity, low moisture content (≤ 3.0%), and reconstitution stability without aggregation.

Leveraging multi-ton raw material integration, domestic chemical precursor supply chains, and specialized automated synthesis equipment to mitigate global shortage risks.
In-house production and direct sourcing of protected amino acids, coupling reagents (HBTU, HATU, DIC), and solid support resins in Zhejiang and Jiangsu chemical clusters, cutting manufacturing costs by 35% compared to Western contract CDMOs.
Equipped with commercial-scale automated peptide synthesizers (up to 1000L solid-phase reactors) and industrial dynamic axial compression (DAC) chromatography columns, enabling single batch delivery from grams up to 25+ kilograms of active peptide API.
Situated within Hangzhou's biopharmaceutical corridor with seamless links to Shanghai Pudong (PVG) international cargo terminals. Dry-ice and cryogenic qualified thermal parcel systems ensure temperature-controlled international transport within 48 to 72 hours.
Global pharmaceutical procurers and compounding pharmacies face stringent scrutiny from health authorities. Thinheal structures regulatory dossiers aligned with FDA, EMA, NMPA, and PMDA expectations.
We provide full Common Technical Document (CTD) format data, including Drug Master File (DMF) open parts, detailed synthetic route validation, impurity justification studies, and stability testing reports according to ICH Q1A(R2) conditions (accelerated and long-term).
Our multilingual desks in Hangzhou provide dedicated support for North America, Western Europe, CIS, Asia-Pacific, and the Middle East, managing customs clearance declarations, non-hazardous chemical transportation certificates, and batch specific release certificates (CoA).
We welcome third-party GMP qualified audits from global partners. Our QA system maintains complete traceability from incoming raw chemical materials to outbound finished lyophilized vials, adhering to 21 CFR Part 210/211 and ISO 9001/13485 standards.
The peptide therapeutics sector is expanding rapidly, transitioning from niche specialty endocrinology treatments to broad preventative and restorative wellness programs.
Unlike recombinant human growth hormone (rhGH), Sermorelin acts directly on the somatotrophs in the anterior pituitary to stimulate endogenous, episodic pulsatile GH release, reducing risks of down-regulating endocrine feedback loops or inducing tachyphylaxis.
Extensively prescribed by private anti-aging, longevity, and sports science clinics to improve nitrogen retention, enhance lean skeletal muscle mass, promote deep restorative slow-wave sleep, and accelerate cellular tissue recovery post-injury.
Emerging research protocols combine Sermorelin with Ghrelin mimetics (e.g., Ipamorelin or GHRP-2/GHRP-6) to trigger synergistic dual-pathway GH release, creating higher sustained therapeutic efficacy for neurodegenerative and cachectic conditions.
Direct technical answers addressing purity, storage conditions, batch testing, customs clearance, and contract manufacturing options.
Our standard commercial supply batches are delivered with ≥ 98.0% purity as assessed by reverse-phase HPLC, with specialized therapeutic batches exceeding 99.0%. Every order includes full HPLC chromatograms and Mass Spectrometry (MS) identification certificates.
Yes. We accommodate both requirements: raw bulk peptide API powder packaged in amber pharmaceutical glass bottles (from 10g to 5kg lots), and sterile lyophilized injection vials (0.5mg, 1mg, 2mg, 5mg/vial) formulated with custom mannitol/saline excipients under aseptic cleanroom conditions.
Lyophilized Sermorelin is stable at ambient room temperature for up to 3 weeks during transit. However, for long-term storage, it must be kept desiccated at -20°C. Once reconstituted with bacteriostatic water, the peptide solution should be stored at 2°C to 8°C and used within 21 days.
Our compliance department prepares custom documentation, including TSCA statements, MSDS, non-hazardous declarations, and origin certificates. We also maintain cold-chain shipping channels with verified global forwarders to ensure trouble-free customs clearance worldwide.
