View brandDetailed compound information
Tesamorelin is a stabilized synthetic analog of growth hormone-releasing hormone (GHRH), engineered with an N-terminal hexenoyl trans-3 modification that resists DPP-IV degradation. The result is a GHRH molecule that survives long enough to drive a clean, pulsatile release of endogenous growth hormone from the pituitary — restoring physiological GH-pulse architecture rather than the flat supraphysiological signal of exogenous rhGH.

Reference material & peer-reviewed citations
Research peptides are chemical reagents for laboratory analysis. Regulations vary by jurisdiction — it is the buyer's responsibility to ensure compliance with local laws. See our Terms & Conditions page for the full regulatory framework across the EU, UK, US, Switzerland, Thailand, and other major markets.
Lyophilized (unreconstituted) peptides should be stored at -20°C for long-term storage or 2-8°C (refrigerated) for short-term use. Once reconstituted with bacteriostatic water, store at 2-8°C and use within 30 days. Avoid repeated freeze-thaw cycles — aliquot into smaller portions if needed.
For laboratory research use only. Not for human consumption, diagnosis, treatment, prevention, or in-vivo administration. By purchasing you confirm you are a qualified researcher or institution.
Reconstitute the 5mg vial with 2mL bacteriostatic water along the interior wall. Swirl gently — do not shake. Yields 2.5 mg/mL. On a U-100 insulin syringe, 40 IU = 0.4 mL = 1 mg. Dose subcutaneous abdomen immediately before bed to align with the natural overnight GH pulse.
Gently inject bacteriostatic water (bacteriostatic water) along the inside wall of the vial — do not spray directly onto the powder. Let it dissolve naturally or gently swirl. Never shake vigorously. Standard reconstitution: add the desired volume of bacteriostatic water based on your concentration needs. For example, 5mg peptide + 2.5ml bacteriostatic water = 2mg/ml concentration.
Yes. Every batch undergoes independent third-party HPLC (High-Performance Liquid Chromatography) and mass spectrometry analysis. We provide a Certificate of Analysis (COA) for each product, verifying identity, purity (≥99%), and the absence of contaminants. COA documents are available for download on each product page.
Yes. We offer temperature-controlled shipping to most EU and Asian countries. Standard EU delivery is 24-48 hours. International orders are shipped in discreet, professional packaging with cold-chain protection where required. Customs documentation and regulatory paperwork are provided as needed.
We currently operate on an inquiry-based ordering system. Submit your order through checkout and our team will contact you within 24 hours to confirm details and arrange payment. We are working on integrating direct payment options for a seamless experience.
