Sermorelin

Description

Sermorelin is supplied by Cytera Peptides as a lyophilised powder in 10mg vials, independently tested by HPLC and mass spectrometry to a minimum of 99% purity. Every vial carries a scannable per-lot certificate of analysis, so the material in your hand can be matched to the exact batch it came from.

Sermorelin is studied in the context of growth hormone axis research. This listing is intended for qualified researchers and laboratory purchasers.

Sermorelin — technical overview

GHRH (1-29) analogue. The material ships as a white to off-white lyophilised cake under vacuum seal. Lyophilisation removes water by sublimation, which is what gives the dry powder its long shelf stability compared with material held in solution.

Each production lot is assayed independently rather than by the manufacturer alone. Reversed-phase HPLC establishes purity as a percentage of total peak area, and mass spectrometry confirms that the molecular weight of the principal peak matches the expected structure — purity and identity are two separate questions, and both are answered before a lot is released.

Certificate of analysis

Every Sermorelin vial is printed with a QR code that resolves to the certificate of analysis for that specific lot — not a generic sample document. The COA states the assay result, the method used, the lot number and the release date. You can browse the full COA library without buying anything.

This matters more in this category than in most. Purity claims are trivially easy to assert and difficult for a buyer to verify, which is why we publish per-lot documentation rather than a single certificate reused across every batch.

Reconstitution and handling

Sermorelin arrives dry and must be reconstituted with bacteriostatic water before any measurement can be made. The resulting concentration depends entirely on how much solvent is added: the same vial can yield very different mg/ml figures. Our free peptide calculator works out concentration, draw volume and insulin-syringe units for any combination.

• Add solvent slowly against the inside wall of the vial, never directly onto the cake.
• Swirl gently to dissolve. Do not shake — foaming indicates denaturation.
• Return reconstituted material to 2–8 °C and avoid repeated freeze–thaw cycles.
• Keep the vial protected from light at all times.

Bacteriostatic water contains 0.9% benzyl alcohol, which allows a vial to be entered more than once. Sterile water contains no preservative and is single use only. Bacteriostatic water and reconstitution supplies are stocked alongside the catalogue.

Published literature on sermorelin

Researchers evaluating sermorelin typically begin with the primary literature. Indexed publications are searchable through PubMed. Cytera does not summarise or interpret findings, and nothing in this listing should be read as a claim about outcomes in any organism.
