Sermorelin

Description

Sermorelin is a synthetic analogue of the first 29 amino acids of human growth hormone-releasing hormone (GHRH 1-29), the shortest fragment of the native hormone that retains receptor activity. It is used in laboratory settings to study GHRH receptor binding, pituitary somatotroph signaling and downstream growth hormone secretion in cell and tissue models. Pure Peptides Canada supplies it as a lyophilized reagent to research laboratories, universities and biotech groups looking for research peptides in Canada with documentation to match. This product is for in-vitro laboratory research only.

Overview

Each vial contains 5mg of Sermorelin as a lyophilized (freeze-dried) powder, sealed under vacuum for stability during cold storage and transit. Lyophilization is the standard format for peptides of this class because the dry state avoids the hydrolysis and aggregation that shorten the useful life of a solution — the reagent stays inert until the researcher reconstitutes it in a solvent appropriate to the assay. Available as a single 5mg vial or a box of ten for laboratories running extended or repeated protocols. Every batch is analyzed by Janoshik, an independent third-party analytical laboratory, with purity determined by HPLC and identity confirmed by mass spectrometry; the certificate of analysis supplied is matched to the specific batch shipped, not a representative document from an earlier lot.

What it is known for

Sermorelin is best known in the literature as the minimum active sequence of GHRH — the truncated 1-29 fragment that still engages the GHRH receptor — which makes it a standard reference peptide in growth hormone axis work rather than a novelty compound. Buyers choose this listing for the paperwork behind it: independent Janoshik testing for both purity and identity, a certificate tied to the batch in hand, and domestic Canadian fulfillment that keeps a temperature-sensitive lyophilized reagent in transit for as short a time as possible.

Key features

• GHRH (1-29) analogue — Gives researchers the established minimum active fragment of growth hormone-releasing hormone, so results can be compared against a large existing body of GHRH receptor literature.
• Lyophilized powder format — The dry state is far more stable than a solution, so the vial can be stored cold and reconstituted only when the assay calls for it, at the concentration and in the solvent the protocol requires.
• Third-party HPLC purity testing (Janoshik) — Purity is verified by a lab with no commercial stake in the result, so impurity load is a known quantity rather than an assumption when interpreting dose-response data.
• Mass spectrometry identity confirmation — Confirms the material in the vial is the peptide named on the label — the check that catches misidentification and substitution before it reaches an experiment.
• Batch-matched certificate of analysis — The COA corresponds to the lot you receive, which is what a supervisor, grant record or method section actually needs to document reagent provenance.
• 5mg vial size — Enough material for a meaningful series of dilutions and replicates from a single reconstitution, without committing to a quantity that will sit past its useful life.
• Box of ten option — Keeps a longer project on a consistent supply of vials and simplifies reordering for labs running repeated or parallel protocols.
• Cold storage and Canadian domestic shipping — Shorter, tracked domestic transit and cold handling reduce the time a temperature-sensitive reagent spends outside controlled conditions before it reaches the bench.

Benefits

• Documented purity and identity you can cite, rather than a supplier claim you have to take on trust
• A stable dry format that lets you control the solvent, concentration and timing of reconstitution
• Consistent lot-to-lot documentation, so variation between experiments is easier to attribute to the model and not the reagent
• Domestic Canadian fulfillment with tracking, avoiding cross-border delays and customs holds on cold-chain material
• Single-vial or ten-pack options to match the scale of a pilot study or an extended protocol
• Discreet, tracked delivery nationwide

Specifications

Typical applications

• In-vitro study of GHRH receptor binding and activation
• Pituitary cell and somatotroph signaling models
• Investigation of growth hormone secretion pathways in cultured tissue
• Comparative work against other growth and signaling peptides
• Reference or control peptide in analytical method development

Important information

• Research use only. Not a drug, supplement, food or cosmetic, and not intended for human or veterinary use, ingestion or administration, or to diagnose, treat, cure or prevent any disease.
• Store the sealed lyophilized vial cold and protected from light; return it to cold storage promptly on arrival.
• Reconstitute only in a solvent appropriate to your assay, and prepare solutions immediately before use where the protocol allows — peptides in solution are considerably less stable than the dry powder.
• Avoid repeated freeze-thaw cycles of reconstituted material; aliquot instead.
• Request the batch-matched certificate of analysis and record the lot number in your experimental documentation.
• Purchase is intended for qualified research buyers and institutional laboratories.

Common questions

What form does Sermorelin arrive in?

As a lyophilized powder in a sealed 5mg vial. It contains no solvent and must be reconstituted in the laboratory before use in an in-vitro protocol.

Who performs the testing?

Janoshik, an independent third-party analytical laboratory. Purity is assessed by HPLC and identity confirmed by mass spectrometry, and the certificate of analysis provided corresponds to the batch shipped.

What is Sermorelin studied for?

It is the 1-29 fragment analogue of growth hormone-releasing hormone and is used in laboratory research on GHRH receptor activity and growth hormone secretion pathways in cell and tissue models. It is not supplied for any use in humans or animals.

How should the vial be stored?

Keep the unopened lyophilized vial in cold storage, away from light and moisture. Once reconstituted, follow your laboratory’s handling procedure, keep the solution cold and avoid repeated freeze-thaw cycles.

What is the difference between the single vial and the box of ten?

Both contain the same 5mg lyophilized vials. The ten-pack is intended for laboratories running longer or parallel protocols that would otherwise reorder repeatedly.

Where does it ship from?

From within Canada, with tracked nationwide delivery in discreet packaging — which keeps transit time for a cold-stored reagent as short as practical.

In summary

A well-documented Sermorelin reagent in the format most laboratories want it: 5mg lyophilized, cold-stored, independently tested for purity and identity, and accompanied by a certificate of analysis tied to the batch you receive. Supplied from Canada for in-vitro laboratory research only.
