About PeptoClinic: how we verify every lot
PeptoClinic supplies research programmes working with synthetic peptides. The work is supply work: sourcing the right compound, verifying what the lot actually contains, and getting it to the destination laboratory with its documentation intact.
What separates one supplier from another in this category is not what they assert about the molecule, but whether they can show the report of the laboratory that measured it. So the full certificates are published, with the laboratory's letterhead and task number, rather than our summary of them.

Why we exist
Research groups routinely wait weeks for reference compounds that arrive without usable documentation, or arrive degraded after sitting in an uncooled warehouse. We built PeptoClinic to close that gap — real cold chain, real third-party assays, and a certificate that names the batch in your hand. The consultation exists because getting that right takes a conversation, not a shopping cart.
How we operate
We source from synthesis facilities that will submit to independent verification, and we publish what the testing lab actually reported rather than a marketing summary. When a batch fails specification, it does not ship. That is the entire policy.
Where we operate
We run supply from Argentina and from the United States. The Argentine operation serves enquiries from the country and the region; the US one serves North American enquiries and institutional accounts. Each dispatches internationally wherever the destination's import rules for research-use materials allow it. Documentation is prepared in English and Spanish, and technical questions are answered by people who can read a chromatogram.
The laboratory reports
We publish 6 Janoshik reports exactly as the laboratory issued them: its letterhead, the report number, the date of the analysis, the purity it found, and the key anyone can use to verify them on the laboratory's own system, without going through us. Each report covers the batch submitted for that analysis and no other — it is evidence about that material, not a guarantee about every vial that ships.

Every intake is reviewed individually by Nayana Ambardekar, MD, alongside the supply team that handles batch documentation, cold chain and customs.

That review is not an in-person examination and does not replace your own doctor. If you are under treatment for anything, or taking anything, the intake asks — the answer is what changes the review.

Frequently asked questions
What is a peptide?
A short chain of amino acids synthesised in a laboratory to a defined sequence, supplied as lyophilised powder in a vial and reconstituted before use. None of them is an approved medicine. Which one applies to a given person, and whether any does, is what the physician's review of the intake decides.
How do I know a lot is what it claims to be?
From that lot's certificate of analysis, not from what the supplier asserts. The certificate names the laboratory that took the measurement, the date, the task number, the method and the purity found. PeptoClinic publishes the full reports uncropped, exactly as the laboratory printed them.
What is a certificate of analysis and how do you read one?
It is the report an analytical laboratory issues on a specific sample. Four things are worth checking: which compound it claims to have measured, by what method (HPLC for purity, mass spectrometry for identity), what figure it found, and whether the task number can be verified against the laboratory. A certificate with no verifiable task number is a picture.
Which countries does PeptoClinic ship to?
Argentina, the United States, Uruguay, Chile, Paraguay, Bolivia, Peru, Brazil, Mexico and Colombia. Each destination is served from whichever operation is closest — Argentina or the United States — on one verification and documentation standard.
Is a prescription required?
You do not bring one. What releases an order is the physician's review of your intake, and that review is part of the consultation itself — PeptoClinic does not ask you for a prescription from elsewhere and cannot accept one in place of the review.
How is the material stored and dispatched?
The peptide travels lyophilised, as a powder, which is the form that tolerates transit. Dispatch leaves in a discreet insulated box with phase-change coolant and tracking, with contents documented as laboratory reference material. Reconstitution happens in the destination laboratory.
