Peptides, in the right order.

A full biomarker panel first — your baseline, properly read. Then, if it is right for you, a medicine registered with the Ministry of Health and dispensed by an authorised pharmacy. Never the other way round.

The basics

What a peptide is

A short chain of amino acids that your body already makes, and uses to carry instructions from one organ to another. Insulin is one. The shape it folds into is what lets it fit a receptor.

A message, not a substance

Semaglutide copies a gut hormone that tells the brain you have eaten.

Registered, not research-grade

Most peptides sold online read “research use only”. Ours are registered with the Ministry of Health.

Not all of them are peptides

Testosterone is a hormone. Metformin is a tablet. The evidence decides, not the word.

How it works

Four steps

Nothing is prescribed before your blood has been drawn and read. We take no margin on your laboratory tests.

  1. 1

    Pre-qualification

    A short questionnaire. Free, no appointment, no clinician. It tells us what to measure, and it rules out anyone this would not be safe for. Not everyone goes further, and that is the point.

  2. 2

    Bloodwork (if applicable)

    Everyone is assessed on blood: the seven baseline markers, plus whatever your answers call for. What varies is only whether you need a fresh draw, or recent results of your own will do.

  3. 3

    Expert plan

    A molecular biologist reads your panel; a physician decides whether medicine is right at all. Either answer comes with a plan — medicine, or nutrition alone. Nobody leaves with nothing.

  4. 4

    Continued monitoring

    Someone stays with you. A repeat panel at three months, then once a year — re-measuring what moved rather than everything, with shorter check-ins in between so nothing drifts unnoticed.

Who reads your results

A physician and a molecular biologist

A panel is only worth what the person reading it knows. These are the people who would read yours.

Prescribing physician

A Costa Rican physician in general practice, with a year of clinical training through the CCSS across primary care, hospital and ambulatory settings. He works daily with chronic pain, sleep disorders and inflammatory conditions, taking an evidence-based approach, and prescribes on what he finds rather than on what is asked for.

Biomarkers

Over thirty years in scientific research as a molecular biologist, now working in functional nutrition. She specialises in functional blood chemistry analysis — reading a panel for the subclinical drift that sits inside the reference range and gets reported as normal. That is the part of this clinic most people underestimate.

Every prescription is written by a physician registered with the Colegio de Médicos y Cirujanos de Costa Rica, after an individual assessment, and dispensed by a licensed pharmacy.

Treatments

Six ways in, one way of working

Every one of them starts with the same assessment and the same seven‑marker panel — blood count, fasting glucose, HbA1c, lipids, liver and kidney function, and thyroid. Which you end up on is your doctor’s decision, not a choice you make on a website.

The Clinic Fee

The same for every patient, whatever your plan.

Initial assessment, 30 minutes$125₡62,500
Monitoring, and your doctor two to three times a year$125/mo₡62,500
Baseline panel, seven markersfrom $219₡109,300
Repeat panel, three markersfrom $106₡53,000
Sometimes the answer is no medicine.The fee buys the assessment and the reading of your results, not a prescription. If your panel says treatment is not right for you, your doctor will say so — and we would rather tell you that here than after you have paid.
Most asked for

Metabolic

1The programme

Weight, insulin resistance, pre-diabetes and the cardiovascular risk that travels with them. The area where the evidence is strongest and the change shows up soonest.

2The medicine
Semaglutide — a peptideYour gut already makes a hormone that tells your brain you have eaten. Semaglutide is a copy of it that lasts longer, so you feel full on less.
Prescribed
Semaglutide, once a week. Tirzepatide where your doctor prefers it, nearer $362 a month.
3The laboratory
TrackedHbA1c, fasting glucose, lipids, liver enzymes, kidney function, blood pressure
from $305per monthapprox. ₡152,500 per month
For men

Men’s hormones

1The programme

Fatigue, lost strength, poor sleep, low mood. Prescribed only where your biomarkers support it, and monitored closely because this one has to be.

2The medicine
Testosterone — a hormone, not a peptideThe level drifts down with age. Replacing it tops up what has fallen, which is why we prescribe it only once your blood has shown that it has.
Prescribed
Testosterone 1% gel, applied daily at home, from a licensed pharmacy.
3The laboratory
TrackedTotal and free testosterone, oestradiol, haematocrit, PSA, lipids
from $277per monthapprox. ₡138,500 per month
For women
A woman in her late forties, relaxed and smiling

Women’s hormones

1The programme

Perimenopause and menopause. Sleep, temperature and mood, and the bone and heart risk that arrives quietly alongside them, years before anyone mentions it.

2The medicine
Progesterone — a hormoneProgesterone usually drops before oestrogen, often years earlier. That is why sleep tends to go first, and why so many women are told it is only stress.
Prescribed
Progesterone, with testosterone added where your own results indicate it.
3The laboratory
TrackedFSH, oestradiol, thyroid function, lipids, vitamin D and calcium
from $220per monthapprox. ₡110,000 per month
Body composition

Growth and recovery

1The programme

Body composition, recovery and sleep. The dose is set on your IGF-1 and adjusted on repeat testing, never on how you happen to feel that week.

2The medicine
Sermorelin — a shorter peptideIt does not replace growth hormone — it nudges your own gland into making more, so the dose follows your IGF‑1 rather than how you feel that day.
Prescribed
Sermorelin, prescribed here and dispensed by a licensed pharmacy.
3The laboratory
TrackedIGF-1, fasting glucose, HbA1c, thyroid function, lipids
from $230per monthapprox. ₡115,000 per month

Metformin

1The programme

The oldest and cheapest option on this page, and for a good number of people the right one. Sixty years of safety data sit behind it.

2The medicine
Metformin — a small moleculeNot a hormone at all. It works in the liver, telling it to release less stored sugar while you sleep.
Prescribed
Metformin tablets, the same medicine your pharmacy already stocks.
3The laboratory
TrackedHbA1c, fasting glucose, renal function, vitamin B12, liver enzymes
from $140per monthapprox. ₡70,000 per month

Cardiovascular

1The programme

Cholesterol, ApoB and the arterial risk that shows nothing at all until the day it does. The area where treating early changes the most, and where waiting costs the most.

2The medicine
A statin — a small moleculeYour liver makes most of your cholesterol, not your dinner. A statin slows that production, which is why diet alone so often fails to move the number.
Prescribed
Atorvastatin or rosuvastatin, one tablet in the evening, from a licensed pharmacy.
3The laboratory
TrackedApoB, LDL, HDL, triglycerides, liver enzymes, HbA1c
from $143per monthapprox. ₡71,500 per month

Every plan: first review at three months, then once a year.

Laboratory figures are the Colegio de Microbiólogos minimum tariff, which is the legal floor in Costa Rica; your laboratory may charge above it, and anything your doctor adds for your own case is extra. Colon figures are converted at ₡500 to the dollar on 22 October 2026, and the rate moves. Package prices are indicative and include the clinic fee above. Medicines are dispensed by a licensed pharmacy and paid for there. Laboratory fees are paid to the laboratory.
