Description
HGH176-191 is a lyophilized peptide reagent for laboratory research use, held by Pure Peptides Canada alongside the rest of our research peptides for Canadian labs. It sits in our Growth & Signaling category and is supplied in sealed 5mg vials, either singly or in a box of ten, for reconstitution in a solvent chosen by the investigator. It is intended for in-vitro and analytical work by qualified researchers, and for nothing else.
Overview
Each vial contains 5mg of HGH176-191 as a lyophilized powder — the dry, freeze-dried form that peptides are normally shipped in because it is far more stable in transit and in storage than a solution. The powder is reconstituted at the bench in a suitable research solvent at whatever concentration the protocol calls for, which leaves the working strength entirely in the researcher’s hands rather than fixed at the point of manufacture. Every batch is sent to Janoshik, an independent analytical laboratory, for HPLC purity analysis and mass spectrometry identity confirmation, and the resulting certificate of analysis is matched to the batch you receive rather than to a representative sample from some earlier production run. Vials are held cold and shipped from within Canada in discreet, tracked packaging.
What it is known for
Buyers choose this reagent for the documentation behind it. Third-party HPLC and MS results tied to the specific batch in the box are the difference between a supplier telling you what is in a vial and an independent lab confirming it — which matters when results have to be defensible and when a reagent of uncertain identity can quietly invalidate weeks of work. The domestic supply chain is the other reason: sourcing within Canada means no international customs hold and no unexplained days at ambient temperature.
Key features
- Lyophilized 5mg vial — The dry form travels and stores far better than a pre-mixed solution, so the reagent arrives in the condition it left in and can be held until the study is ready for it.
- Independent HPLC purity testing (Janoshik) — Purity is verified by a lab with no stake in the sale, so you are not relying on the vendor’s own assurance when you record reagent provenance.
- Mass spectrometry identity confirmation — Confirms the material in the vial is the peptide named on the label — the check that catches mislabelling and substitution before it reaches your bench.
- Batch-matched certificate of analysis — The COA corresponds to the lot you actually receive, which is what an audit, a supervisor or a methods section requires.
- Two pack formats — single vial or box of ten — Take one vial to trial a protocol, or a full box when a study is scoped and you need consistent material across every run.
- Cold storage and tracked domestic shipping — Held cold before dispatch and shipped from Canada with tracking, so transit time is short and the package can be accounted for from door to door.
- Discreet packaging — Nothing on the outer packaging describes the contents, which suits shared receiving areas and mailrooms.
Benefits
- Documented purity and identity you can cite, rather than an unverified label
- Reconstitute at the concentration your protocol requires instead of working around a fixed dilution
- Consistent material across a study when ordered as a box of ten
- Short domestic transit with tracking, avoiding cross-border delays
- A stable dry format that can be stored until the experiment is scheduled

- Reference material for comparison against in-house or incoming lots
- Multi-run studies where consistent batch material is needed across experiments
Important information
- Research use only. This product is not a drug, supplement, food or cosmetic, is not intended to diagnose, treat, cure or prevent any disease, and is not for human or veterinary use, ingestion or administration.
- Keep the vial cold and sealed until you are ready to reconstitute; the lyophilized form is the stable form.
- Choose a reconstitution solvent appropriate to your protocol and handle under the conditions your lab’s procedures specify.
- Once reconstituted, store and handle the solution according to your own validated practice — a solution is less stable than the dry powder.
- Request the batch-matched certificate of analysis and file it with your lot records before use.
- Order by attribute: the single 5mg vial and the box of ten are the same material in different pack sizes.
Common questions
What is in the vial and what form is it in?
5mg of HGH176-191 as a lyophilized (freeze-dried) powder. It is not pre-mixed and requires reconstitution in a research solvent of your choosing before use.
Who performs the testing?
Janoshik, an independent third-party analytical laboratory, runs HPLC for purity and mass spectrometry for identity on each batch.
Does the certificate of analysis match my specific vial?
Yes. The COA is matched to the batch you receive, not to a generic or historical lot.
Where does it ship from?
From within Canada, cold-stored before dispatch and sent tracked in discreet packaging, which keeps transit short and avoids international customs delays.
Can I buy a single vial before committing to more?
Yes. It is available as a single 5mg vial or as a box of ten, so you can qualify the material against your protocol first and then order at study scale.
Can this be used in humans or animals?
No. It is supplied strictly for in-vitro laboratory research by qualified researchers and is not for human or veterinary use, ingestion or administration.
In summary
A 5mg lyophilized HGH176-191 reagent with independent HPLC and MS results tied to the batch you receive, shipped cold and tracked from within Canada, in single vials or boxes of ten. Strictly for laboratory research use.
