About PeptoClinic: how we verify every lot
PeptoClinic works with synthetic peptides: sourcing the right compound, verifying what the lot actually contains, and getting it to you with its documentation intact. A physician reviews every consultation before anything ships.
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
Plenty of people buy peptides that arrive without usable documentation, or degraded after weeks in transit. We built PeptoClinic to close that gap — sealed lyophilised material that holds up on the route, real third-party assays, and a certificate that names the batch in your hand. And a physician reviews every consultation before an order ships.
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 operate 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 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 43 Freedom Diagnostics 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 Dr. Emily Parker, alongside the supply team that handles batch documentation, packaging and customs.

Reviews every consultation as it comes in
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
Is PeptoClinic legit? How can I check?
You can check it without taking our word for it. Every laboratory analysis we publish carries the report number and the key of the laboratory that ran it, so you can verify it in the lab's own system. We are based in Garín, Buenos Aires province, Argentina, with a Google Maps listing; on Instagram we are @peptoclinic.ok; and we answer at [email protected] and on WhatsApp. The site is peptoclinic.com, spelled with an "o".
Is PeptoClinic the same as PeptiClinic?
No. PeptoClinic is spelled with an "o" and its site is peptoclinic.com. PeptiClinic, with an "i", is a different company with no connection to us. Because the names are similar, search engines sometimes correct one into the other.
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 and the United States. Argentina is dispatched from Garín, Buenos Aires; the United States from our US operation. We do not ship to other countries.
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: it stays stable at room temperature for weeks, so no cold chain is needed. Dispatch leaves in a discreet box with tracking.
