Evidence-first · UK

Peptide therapy, the honest version.

A small number of peptides are licensed medicines in the UK with strong human trial evidence. Most of the peptides sold by wellness clinics are unregulated research chemicals with limited or no human data. We help you tell them apart, and match you to a GMC-registered specialist who prescribes what is licensed and evidenced for your goal.

Why patients choose us

  • 01

    Evidence-first, not marketing-first

    We only recommend peptides with UK marketing authorisation and quality human trial data. We do not sell or refer for grey-market research peptides.

  • 02

    Licensed alternatives, on a GMC route

    For weight, hormones, hair, libido and recovery, there are evidence-based licensed options. We match you to a GMC-registered specialist who prescribes them.

  • 03

    Independent, and free

    We are paid by no clinic, so the recommendation is impartial and costs you nothing.

Indicative pricing

What a licensed, evidence-based programme costs.

For context, grey-market peptide stacks sold by wellness clinics typically run £150–£450 per month with no MHRA oversight. Licensed treatments vary by drug and by dose.

In short

Evidence-based, licensed, GMC-prescribed: £250–£850 for a proper first consultation and month one.

Programme Indicative range
Evidence review and specialist matching Free
GLP-1 weight-loss programme (semaglutide, tirzepatide) - month 1 £250–£450
Testosterone replacement therapy - initial workup + first month £450–£850
Menopause consultation with body-identical HRT initiation £280–£450
Teriparatide (licensed peptide for severe osteoporosis) £350–£550/mo
Second opinion on a peptide plan you have been offered elsewhere £250–£400

We do not sell, prescribe, arrange or refer for research peptides such as BPC-157, TB-500, ipamorelin, CJC-1295, MOTS-c, Semax, Selank or Melanotan. If a clinic quotes you a monthly stack of those, we will happily give you an honest second opinion at no cost.

The problem

Wellness marketing has outrun the science.

London wellness clinics increasingly offer peptide stacks for weight, recovery, hair, libido and longevity. Most of those peptides are research chemicals without UK licences or human trial evidence.

  • Is it actually licensed in the UK?

    GLP-1s, teriparatide, goserelin, leuprorelin, desmopressin and oxytocin are. BPC-157, TB-500, ipamorelin, CJC-1295, MOTS-c, Semax and Selank are not.

  • Is there human trial evidence?

    For most of the popular peptides sold in wellness clinics the published evidence is animal studies, small unblinded case series, or open-label reports. That is not the same as an RCT.

  • Who is actually prescribing it?

    Ask whether the prescriber is a GMC-registered specialist for your condition, and whether the clinic is CQC-registered with a named Responsible Officer.

The journey

From your goal to a written, evidence-based plan.

One team, from first message to the follow-up review - matching you to a GMC-registered specialist for the goal you actually have.

  1. 01

    Before

    You tell us the goal

    Weight loss, hormone symptoms, hair thinning, recovery, libido, longevity - a short, confidential form. Not the specific peptide you have read about, the outcome you want.

  2. 02

    Before

    We do an evidence check

    Within one working day we come back with what is licensed in the UK for your goal, what has quality trial data, and what is currently sold as an unregulated research chemical.

  3. 03

    Before

    We match you to a GMC specialist

    An obesity physician, endocrinologist, dermatologist, sports physician or menopause specialist - depending on the goal - who prescribes licensed treatments on the UK label.

  4. 04

    On the day

    Consultation and baseline tests

    A full history, medication review, examination and the right baseline bloods. Not a same-day injection - a proper clinical assessment.

  5. 05

    On the day

    A written plan

    Which licensed treatment fits, expected effect size from real trial data, side-effect profile, monitoring plan, and how to stop. In writing, for your GP.

  6. 06

    After

    Monitoring and honest review

    Bloods, symptom scores or weight at defined intervals. If it is not working, we stop and reconsider - rather than escalating a stack.

  7. 07

    After

    If you still want a peptide we do not offer

    We tell you what the evidence actually says, what the sterility, purity and dosing risks are, and what a GMC-registered prescriber will and will not do. Your decision, informed.

What to actually consider

The evidence-based first step for the goals peptides are sold for.

For each common reason people ask about peptides, there is usually a licensed, evidence-based first step. Start there.

  • Weight loss you want a peptide for

    For most adults with BMI in range, a licensed GLP-1 (semaglutide, tirzepatide) has strong RCT evidence. We match you to a GMC-registered obesity physician.

  • Hair thinning or androgenetic alopecia

    Evidence-based options: topical minoxidil, oral finasteride or dutasteride, PRP, low-level laser, and transplant - not GHK-Cu or unlicensed peptides.

  • Low libido or erectile symptoms

    Confirm hypogonadism with morning testosterone (twice) before TRT. PDE5 inhibitors for ED. PT-141 is licensed in the USA, not the UK.

  • Menopause symptoms

    Body-identical HRT is the evidence-based treatment for vasomotor symptoms, bone and mood. Oxytocin nasal sprays are not licensed for menopause in the UK.

  • Sports injury or slow recovery

    BPC-157 and TB-500 have no human RCT evidence and no UK marketing authorisation. Physiotherapy, load management, and PRP for selected tendinopathies.

  • Anti-ageing and longevity

    Mediterranean diet, resistance training, sleep, tobacco and alcohol cessation - and topical retinoids for skin. MOTS-c and epithalamin have no human outcome data.

  • Cancer hormonal treatment

    Goserelin and leuprorelin are licensed peptide analogues prescribed by oncologists for prostate and breast cancer - not wellness clinic products.

  • You have been sold a peptide stack

    Bring the labels, the invoice and the injection schedule. We will tell you what is licensed, what is grey-market, and what to raise with your GP.

Peptide categories

Licensed, imported, research chemical, or illegal.

A plain-English map of the peptides you may have been offered. Know which bucket the vial actually sits in before you inject.

  • Licensed in the UK - well evidenced

    GLP-1 receptor agonists (semaglutide, tirzepatide, liraglutide), teriparatide for severe osteoporosis, desmopressin for diabetes insipidus and nocturnal enuresis, goserelin and leuprorelin for hormone-sensitive cancers, and oxytocin for obstetric use.

  • Licensed abroad, not in the UK

    Bremelanotide (PT-141) is FDA-approved for hypoactive sexual desire disorder in premenopausal women in the USA but has no UK marketing authorisation. Importing is a personal-use grey zone with real safety questions.

  • Research chemicals with no human trials

    BPC-157 and TB-500 are sold widely for tendon and ligament recovery. The published evidence is almost entirely in animal models. There are no adequately powered human RCTs, and no UK licence.

  • Grey-market growth hormone secretagogues

    Ipamorelin, CJC-1295 and similar peptides raise growth hormone and IGF-1. Sold as anti-ageing or muscle-gain products. Not licensed in the UK, purity varies, and long-term safety data are absent.

  • Longevity peptides marketed without evidence

    MOTS-c, epithalamin and similar mitochondrial or pineal peptides are marketed for lifespan extension. No human outcome trials, no licence, unclear pharmacokinetics.

  • Nootropic peptides from other jurisdictions

    Semax and Selank are used in Russia as nootropics. They are not licensed medicines in the UK, and the published evidence base is small, mostly non-blinded, and hard to appraise.

  • Illegal in the UK - MHRA enforcement

    Melanotan I and Melanotan II are unlicensed and specifically warned against by the MHRA and NHS. Documented harms include melanoma, changes in existing moles, nausea, and priapism.

  • Compounded peptides from wellness clinics

    Peptides mixed at a compounding pharmacy for a single named patient sit in a grey zone. Sterility, potency, dose, batch consistency and adverse-event reporting are usually not audited to MHRA GMP standards.

Safety concerns

What is unknown about grey-market peptides.

Sterility, purity, dose accuracy, contamination, adverse-event surveillance and drug interactions are all essentially unknown for peptides sold as research chemicals or compounded outside GMP standards.

  • Sterility and contamination

    Grey-market peptides are commonly imported as research chemicals not made to GMP standards. Endotoxin, bacterial and heavy-metal contamination have all been reported. You cannot verify a vial with the naked eye.

  • Purity and dose accuracy

    Independent testing of grey-market vials has repeatedly found the labelled peptide missing, degraded, or present in the wrong quantity. That means you cannot predict effect or side effect.

  • No adverse-event system

    Licensed medicines feed into the MHRA Yellow Card scheme. Grey-market peptides do not - so serious adverse events in the community are not tracked and not fed back to prescribers.

  • Growth hormone stack risks

    Sustained IGF-1 elevation from CJC-1295 or ipamorelin stacks has theoretical cancer, cardiovascular and metabolic risks that no long-term human trial has quantified.

  • Melanotan and melanoma

    Melanotan II is linked to changes in moles and to melanoma in case reports. The MHRA has taken enforcement action against UK sellers. Do not use it.

  • Interactions with real medicines

    Peptides can interact with anticoagulants, hormones, diabetes medications and psychiatric drugs. A wellness clinic that does not take a full drug history is not a safe route to prescribe them.

  • Injection technique and infection

    Repeated subcutaneous injection carries infection, lipohypertrophy and nerve injury risk. Training and sharps disposal matter.

  • Pregnancy, breastfeeding and fertility

    Almost all research peptides have zero human reproductive safety data. Do not use any peptide in pregnancy or when trying to conceive without a specialist assessment.

  • Red flags: stop and seek help

    New chest pain, breathlessness, jaundice, sudden mood change, a changing mole, prolonged priapism, or a hard lump at an injection site - stop, seek medical assessment the same day, and bring the vials.

Reading your plan

Your plan in four parts. Read the last one first.

Whichever licensed treatment fits your goal, the plan your specialist sends you keeps to the same shape.

A quiet reminder

If a plan skips baseline tests, monitoring intervals and a stopping rule, it is not a plan.

Frequently asked

Peptide therapy, straight answers.

Legality, safety, licensed alternatives, and what the MHRA actually says.

  • Is BPC-157 legal in the UK?

    BPC-157 is not a licensed medicine in the UK. It is sold online as a research chemical, labelled not for human use. Selling it for human use, or as a medicine, is unlawful under the Human Medicines Regulations 2012. Personal possession is a legal grey zone, but no GMC-registered prescriber can lawfully prescribe it for you.

  • How safe are grey-market peptides bought online?

    The honest answer is that you cannot tell. Independent testing of vials sold as BPC-157, TB-500, ipamorelin and CJC-1295 has found variable potency, missing active ingredient, and bacterial and endotoxin contamination. There is no MHRA oversight, no Yellow Card system, and no batch traceability. Any injectable that has not been made to GMP standards carries a real infection and adverse-event risk.

  • What are the licensed alternatives for the things peptides are sold for?

    For weight loss, licensed GLP-1 receptor agonists (semaglutide, tirzepatide, liraglutide) have strong RCT evidence. For hair loss, minoxidil, finasteride, PRP and transplant. For low libido or hypogonadism, testosterone replacement after proper diagnosis, and PDE5 inhibitors for ED. For menopause, body-identical HRT. For recovery, physiotherapy and PRP for selected tendinopathies. For osteoporosis, teriparatide is a licensed peptide prescribed by specialists.

  • Does TB-500 work for tendon and ligament injuries?

    The mechanistic and animal evidence for thymosin beta-4 fragments in tissue healing is interesting, but there are no adequately powered human randomised controlled trials in tendon, ligament or muscle injury. Marketing claims run well ahead of the clinical evidence, and TB-500 is not a licensed medicine in the UK. The evidence-based first step for most tendinopathy remains progressive loading physiotherapy.

  • Will my insurer cover peptide therapy?

    UK private medical insurers generally cover licensed treatments prescribed for a diagnosed medical condition - for example, teriparatide for severe osteoporosis, or GLP-1 medications when funded criteria are met. They do not cover research peptides, wellness compounded peptides, or off-licence use for anti-ageing or longevity. We confirm cover in writing before booking.

  • What is the MHRA position on peptides sold by wellness clinics?

    The MHRA has issued specific warnings and taken enforcement action against unlicensed peptides sold in the UK, most publicly against melanotan. Peptides sold as research chemicals are not for human use. Compounded peptides supplied from a pharmacy for a named patient sit in a narrower grey zone, but sterility, potency and pharmacovigilance are frequently not audited to the same standard as a licensed medicine.
