Peptides, verifiable lot by lot.
We are a supply consultancy, not a checkout. Tell us what your programme needs and our technical team reviews compound, purity spec, quantities, batch documentation and the route to your bench — then sends you a written quote.
No prices are published. Every compound is quoted through a technical consultation.
Verification of purity, not promises
Purity claims are only worth anything if you can check them. Here is exactly what we test and how you can audit it.
- Batch-level CoA included
- A certificate of analysis matched to the exact batch you would receive
- ≥99% HPLC purity
- Third-party HPLC and mass spectrometry verification
- Cold chain on every dispatch
- Lyophilised powder sealed under inert atmosphere
- Technical support in Spanish & English
- A dispatch route and customs pack prepared for your destination
Read the lab report before you read our copy
Anyone can write “≥99% purity”. These are the analyses behind that number: a named laboratory, a dated report and a link that leaves this site for them.

Faultless delivery
I ordered in the morning and it arrived the same day, in thermal packaging with the vial sealed. The COA matched the lot number. Very professional.
Mateo
First-rate support
They answered every question over WhatsApp before I ordered and sent the lot's certificate of analysis without my having to ask twice.
Diego
All of it checkable
I compared the COA against the lot on the vial and it matched exactly. The care shows in the packaging, the cold chain and the paperwork.
Nicolás
Quick and serious
We sorted everything over WhatsApp in minutes. The parcel arrived the same day, with refrigerant and well protected. No runaround.
Lucas
Complete documentation
The only supplier who sent me the full chromatogram and lot analysis before I bought. That builds a lot of confidence.
Tomás
Would order again
Clear pricing, punctual shipping and support that answers at any hour. The product quality and the documentation are on another level.

What is Peptide Therapy?
Peptides are short chains of amino acids — think of them as tiny messengers that tell your cells how to function. These powerful proteins occur naturally in your body. However, at age 30 we start losing them. Peptides play a huge role in processes like healing, weight management, energy levels, and even how you age.
Peptide therapy is a cutting-edge treatment designed to support your body's natural processes by using peptides to promote healing, enhance performance, and improve overall wellness.

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.
Why does PeptoClinic publish no prices?
Because there is no single price. Cost turns on quantity, vial size, the documentation the programme needs and the dispatch route. Each compound is quoted in writing after a free, no-obligation technical consultation, normally within one business day.
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 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 ship
Transit is quoted per destination, because import rules for research-use materials differ by country. Every cross-border shipment carries research-use declarations and a safety data sheet.
