Prescribed when the panel asks. Not before.
Six classes, each graded by how strong the human evidence actually is.

Same method at every depth. What changes is how long we stay with it.
The body already speaks this language.
- 01
What they are
Short chains of amino acids, the same units the body builds every protein and hormone from. Short enough to act as a message rather than as a structure.
- 02
How they work
Each one has a shape that fits a particular receptor on a particular cell, and that fit triggers one response. The body already runs on this. A peptide protocol borrows the mechanism deliberately.
- 03
Why the precision cuts both ways
A narrow target means a narrow effect. Matched to the right problem, that is the advantage. Matched to the wrong one, it does nothing at all, which is most of what the grey market sells.
One distinction to hold onto: a peptide is not a vitamin and not a supplement. Used clinically it is a prescription medicine, even when the sequence is one your own body makes. Anyone selling you it as wellness has skipped the part where a doctor decides.
Six classes. Graded by what is actually known.
The limit comes before the promise on every one of these, because the limit is the part nobody else will show you.
Licensed by a major regulator for a named condition, on the back of completed human trials.
Randomised human trials exist and are published, but the molecule is not licensed for this use.
Small human studies or a single research group. Real signal rather than yet a settled answer.
Animal or laboratory data only. No published randomised human trial.
- Approved
Metabolic regulators
GLP-1 and related incretins
Semaglutide, tirzepatide
Blunt appetite signalling and slow gastric emptying, which moves weight, glucose control and the lipid picture together.
The limitThe strongest evidence base on this page, and the most over-prescribed class in the region. It treats a metabolic problem; it does not treat wanting to be thinner.
Considered whenInsulin resistance, HbA1c or body composition that has not moved on a real training and nutrition plan.
- Emerging
Growth hormone axis
Secretagogues
Tesamorelin, sermorelin, ipamorelin, CJC-1295
Prompt the body's own growth hormone release rather than replacing it, with the intent of supporting recovery, body composition and sleep.
The limitThese reliably move IGF-1 on a blood test. Whether moving IGF-1 makes a healthy adult better at anything is a separate question, and it has not been answered. Tesamorelin is the only one licensed anywhere, for one specific condition.
Considered whenA documented deficit on the panel alongside a clinical picture. Never for cosmetic or performance reasons.
- Preclinical
Tissue repair
Regenerative signalling
BPC-157, TB-500
Widely used after soft-tissue injury and surgery on the strength of animal work and clinical anecdote.
The limitAfter three decades of animal work, BPC-157 has no approved formulation, no validated dose and no completed phase II trial. If somebody sells you this as proven, they have not read it.[2]
Considered whenConsidered only alongside physiotherapy and rehabilitation, for an identified injury, with the state of the evidence put in writing first.
- Trialled
Immune modulation
Thymic peptides
Thymosin alpha-1
Regulates immune response. Trialled in hepatitis B and C, sepsis and aspergillosis, and used in thousands of patients.
The limitRegistered in a number of countries, but not licensed by the FDA or the EMA, which is why it is graded trialled here rather than approved. Dose, schedule and what to measure remain unsettled, and the evidence in otherwise healthy adults is thin, exactly the population most likely to be sold it.[1]
Considered whenInflammatory and immune markers that are genuinely abnormal rather than a run of ordinary winters.
- Trialled
Sexual and reproductive axis
Melanocortin and kisspeptin
Bremelanotide, kisspeptin-54
Act on the brain's desire and reproductive-axis pathways rather than on blood flow, which is what separates them from the familiar tablets.
The limitBremelanotide is licensed for one condition in women. Kisspeptin has real trial data, and the short grey-market form sold online is not the form that was studied.
Considered whenA hormonal panel and a history that support it, after the ordinary causes have been ruled out.
- Preclinical
Longevity and mitochondrial
Cellular signalling
Epitalon, MOTS-c
Target the cellular-ageing and mitochondrial pathways that longevity research is currently most interested in.
The limitMouse data and one or two small studies from single research groups. This is the class with the biggest gap between how it is marketed and what is known, and it is the class Orba is slowest to reach for.
Considered whenOnly for someone already doing the things that are proven: strength, cardiorespiratory fitness, sleep, metabolic health, and told plainly that this is the speculative end.
Four rules we do not bend.
Not disclaimers. This is how you can tell whether any peptide programme, ours or anyone’s, is being run as medicine or as retail.
The panel decides. Neither you nor we do
A peptide is proposed when your results show a specific thing to correct. Asking for one by name is not an indication, and neither is reading about it. If the data does not support it, you will be told no and told why.
You are told what is known before you decide
Every class on this page carries an evidence grade, and you get it in writing before anything is prescribed, including when the honest grade is 'nobody has tested this in people'. Consent that skips that is not consent.
Prescribed against a marker, reviewed against the same marker
Whatever justified the prescription is what gets re-measured. If it has not moved by the review, the prescription stops. A protocol does not continue because you have got used to it.
Never part of a package
Peptides are not in a membership tier, a retreat or an experience. They are individual prescriptions, individually justified. A clinic that bundles them has decided what you need before it met you.
Where we are with this
Prescribing peptides in Thailand runs through a licensed physician and a licensed compounding pharmacy, with a certificate of analysis on every batch. Orba is putting that chain in place, the licence and a supplier we are willing to put our name to, and will not prescribe from this page until both are done. Other Bangkok clinics work this way already; we would rather be late than be sourcing from somewhere we cannot audit.
Until then, this page exists so you can judge the evidence for yourself, and judge anyone else who offers you these.
What people ask.
Before anything is prescribed, and often instead of it.
