PT141

Description

PT141 is a synthetic melanocortin peptide supplied as a lyophilized reagent for laboratory investigators working with melanocortin receptor systems. Like the rest of our research peptides in Canada, it arrives as a dry vial for reconstitution in a solvent of the researcher’s choosing, accompanied by third-party analytical data tied to the specific batch in the box. It is a research chemical: not a drug, supplement or cosmetic, and not for human or veterinary use.

Overview

Each vial contains 10mg of PT141 as a lyophilized powder — freeze-dried rather than supplied in solution, because the dry state is the stable state for a peptide of this kind and lets the researcher control the solvent, concentration and buffer used in their own protocol. Vials are available singly or in a box of ten for laboratories running extended work or parallel conditions who want material from a consistent production run. Before release, each batch goes to Janoshik, an independent analytical laboratory, for purity determination by HPLC and identity confirmation by mass spectrometry. The resulting certificate of analysis is matched to the batch you receive, not a generic document reused across production runs. Orders are held cold, packed discreetly and shipped from within Canada with tracking.

What it is known for

PT141 is one of the melanocortin-family peptides most often requested by researchers, and buyers select a given supplier on two things: whether the analytical data is independent and batch-specific, and whether the material can be sourced domestically without an international customs delay. This listing addresses both — Janoshik HPLC and MS results tied to the lot number, and a Canadian-owned operation shipping domestically rather than drop-shipping from overseas.

Key features

• Lyophilized 10mg vial — Dry powder is the stable presentation for peptide storage and transit, and it leaves reconstitution volume and buffer choice entirely in the researcher’s hands rather than fixing a concentration you then have to work around.
• Third-party HPLC purity testing — Purity is determined by an outside laboratory rather than asserted in-house, so the number on the certificate is not the seller marking their own work.
• Mass spectrometry identity confirmation — Confirms the material’s molecular mass matches PT141 — the check that distinguishes correct peptide from a mislabelled or substituted one, which purity alone will not catch.
• Batch-matched certificate of analysis — The document corresponds to the lot in your vial, so it can be filed against the experiment and referenced if a result needs to be traced back to material quality.
• Single vial or box of ten — Take one vial for a pilot or method development, or ten from the same production run when you need consistent material across a longer series and want to avoid batch-to-batch variation as a confounding variable.
• Cold storage and discreet, tracked Canadian shipping — Material is handled cold before dispatch and moves domestically, so transit is short and traceable and the parcel gives nothing away on the outside.
• Melanocortin-family reagent — Sits alongside related compounds in receptor and pigmentation-focused research programs, so it can be worked into comparative studies with other peptides in the same class.

Benefits

• You can verify what you received rather than trust a claim — the analytical work is independent and specific to your batch.
• Domestic dispatch keeps transit short and avoids the customs uncertainty that comes with importing research reagents.
• Freeze-dried format lets you set concentration and solvent to suit your protocol instead of adapting to a pre-mixed solution.
• Buying ten vials from one run removes material variation as a variable across an extended set of experiments.
• Documentation is ready to file against the work, which matters when results need to be defensible later.

Specifications

Typical applications

• In-vitro melanocortin receptor studies
• Comparative work across peptides within the melanocortin family
• Analytical method development and reference work
• Assay development and validation requiring a characterized peptide input

Important information

• Research use only. Not a drug, supplement, food or cosmetic. Not for human or veterinary use, ingestion or administration, and not intended to diagnose, treat, cure or prevent any disease.
• Request or download the certificate of analysis for your batch and check the lot number matches the vial before beginning work.
• Store the vial cold and keep it sealed until reconstitution; lyophilized peptide is stable in the dry state, reconstituted peptide is not, and should be handled according to your laboratory’s own protocol for solution stability.
• Reconstitute with a solvent appropriate to your assay. Choice of solvent, concentration and buffer is the researcher’s responsibility.
• Handle with standard laboratory practice — gloves, clean technique, and dating of any prepared solution.

Common questions

What form does PT141 arrive in?

A sealed vial of lyophilized (freeze-dried) powder containing 10mg. It is not supplied in solution, so you reconstitute it yourself in whichever solvent your protocol calls for.

Who performs the testing?

Janoshik, an independent analytical laboratory, runs HPLC for purity and mass spectrometry for identity. The results are issued per batch, not as a one-off certificate reused across production.

Is the certificate of analysis specific to my vial?

Yes. The COA is matched to the batch you receive, so the lot number on the document corresponds to the lot on the vial.

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

The box supplies ten 10mg vials, which is the option to take when you need enough material for a longer series and want it drawn from consistent production rather than accumulated across separate orders.

Where does it ship from and how is it packaged?

It ships domestically from Canada with tracking, held cold before dispatch and packed discreetly so the contents are not identifiable from the outside of the parcel.

Can I use this on myself or an animal?

No. This is a laboratory reagent sold strictly for in-vitro research. It is not a drug or supplement and is not intended for human or veterinary administration in any form.

In summary

A 10mg lyophilized PT141 vial with independent HPLC and mass spectrometry data attached to the batch, available singly or in tens, shipped cold and tracked from within Canada. Strictly for in-vitro laboratory research.
