I am back in clothes I had put away

I had been trying to lose weight for a long time, but I always ended up giving up. The hardest part for me was controlling portions and cravings. With the support I started to feel that keeping to a routine was much easier. Over time the weight came down and I ended up wearing clothes I had had put away for years.

I stopped thinking about food all day

My problem was never not knowing what to eat. I knew perfectly well what I had to do, but by the afternoon I would end up picking at whatever was around. The first thing I noticed was that eating normal portions became much easier. Then the scale started to move as well, and that motivated me a great deal more.

I thought I was going to quit again

I had tried diets a thousand times and I always lasted two or three weeks. This time I went about it differently and made changes little by little. When I started to see the weight come down without feeling that I was constantly on a diet, I decided to carry on. The best part was getting my consistency back.

I feel comfortable in a T-shirt again

After 40 I started putting on weight, and there came a point where I avoided certain T-shirts because I did not like how they looked on me. I started the process without expecting a huge change, but little by little I noticed a difference at the waist and in my clothes. That is what motivated me most.

I noticed the difference in my clothes first

At first I was weighing myself every day and it was driving me mad. Then I stopped. One day I put on a pair of jeans that used to be tight on me and they were loose. That was when it hit me how much had changed.

FAQ

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".

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.

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.

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.

Virtual Consultation

The consultation is reviewed by a physician. Tell us what you are looking for and the intake will ask what he needs in order to review it.

No payment. No account. No obligation. One business day response.

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

International transit is quoted per destination, because import rules differ by country. Every cross-border shipment carries its documentation and a safety data sheet.

  • Argentina
  • United States

Supplied only after a physician reviews your intake. Not evaluated or approved by the FDA or ANMAT.
