Steroids in the UK: Know the Law and the Risks

Our approach

Before You Buy, Read the Evidence

Supplement marketing promises more than the research supports. We judge every ingredient on four things and publish the result on the product page, including when the honest answer is that it will not do much for you. The method is set out in our editorial policy.

The ingredient

What it is and what the body does with it, without borrowed claims from a different form or dose.

The dose

The amount used in the studies compared with the amount in the scoop.

The evidence

How strong the research is: many trials in people like you, or a handful of small ones.

The limitations

What it will not do, who should not take it, and when food does the job for less.

The shop

Testosterone support and legal supplements, dosed as the research says

No hormones, no prohormones, nothing that needs a prescription. Where an ingredient has no authorised claim behind it, we say so on the page rather than implying one.

22 products
15 products

Four ranges cover most of what anyone actually needs. Here is what each one does, who it suits, and the dose the research supports, so you can rule things out before you spend.

RangeWhat it actually doesWho it suitsTypical dose
ProteinCovers your daily protein target on the days food alone falls short. Convenience, not magic.Anyone eating under roughly 1.6g of protein per kg of bodyweight a day20g to 40g per serving
CreatineThe most tested ergogenic aid there is. Small, repeatable gains in strength and training volume.Almost anyone training for size or strength3g to 5g daily, timing does not matter
Amino acids and BCAAAdds very little once your daily protein target is met. If you use them anyway, EAA beats BCAA on the evidence.Fasted trainers, or anyone who struggles to hit protein from food5g to 10g around training
Vitamins and mineralsFills the gaps a normal UK diet leaves. Vitamin D through the winter is the clearest case of all.Most people between October and MarchPer label. The NHS advises 10 micrograms of vitamin D a day

Dosing guidance follows the NHS vitamin D advice. Where a claim is not authorised for use in Great Britain, the product page says so rather than implying a benefit.

Testosterone and TRT

Testosterone, TRT and Steroids Are Not the Same Thing

These five words get used as if they were interchangeable, and that confusion causes real harm. Here is the difference in one line each. The full picture, including how diagnosis works on the NHS and privately, is in our TRT UK guide.

Testosterone

The main male sex hormone, made mostly in the testicles and controlled by signals from the brain.

Low testosterone

A medical condition diagnosed from symptoms plus at least two early morning blood tests.

TRT

Prescribed treatment that restores normal levels in diagnosed deficiency, with regular monitoring.

Anabolic steroids

Testosterone and its derivatives used above normal levels to build muscle. Class C in the UK.

Testosterone support supplements

Nutrients such as zinc with a small authorised claim. They do not treat deficiency.

NHS or private?

How the two routes to TRT compare on speed, cost, thresholds and monitoring.

How it works

How ordering works, start to finish

01. Check the dose

Every product page prints what is in it and at what dose. Compare it against the research before anything goes in the basket.

02. Build your order

Filter by category or work from the comparison above. Nothing here is a subscription and nothing renews on its own.

03. Checkout securely

Card details go straight to the payment provider and are never stored on our systems. Your delivery estimate is shown before you pay.

04. Tracked to your door

UK orders are dispatched on working days, and your dispatch confirmation carries the tracking details.

Why buy from us

Four things that are unusual in testosterone supplements

Every dose printed

No proprietary blends. A blend giving only a total weight exists to hide how little of the expensive ingredient made it in.

Only authorised claims

We use only health claims on the GB register. Where a botanical has none, the page says so instead of implying a benefit.

We will tell you not to buy

Several product pages say the product does very little if you already hit your protein target. That costs sales and earns attention.

Clear labels

Every product page lists each active ingredient and its dose, so you can compare like with like before you buy.

The detail

Everything else worth knowing before you buy

The full picture on the law, the side effects, what we will and will not sell, TRT, how these pages are written and how delivery works. Open whichever matters to you.

Table of testosterone esters including propionate, enanthate, cypionate, undecanoate and the Sustanon blend, with how each differs in duration and use

Anabolic steroids are Class C controlled drugs under the Misuse of Drugs Act 1971. That sentence gets repeated across the internet without anyone explaining what it means for you, so here is the version that matters.

Possession for personal use is not an offence. You can hold anabolic steroids in a medicinal form for your own use without committing a crime, which surprises most people because it is the opposite of how the other drug classes work. Carrying them into the country yourself, for yourself, is also permitted.

Supply is where the law turns hard. Supplying or offering to supply carries up to fourteen years and an unlimited fine. Supply does not only mean selling. Handing a vial to a training partner is supply. Splitting an order with two friends is supply. Posting them is supply and importation together, and Border Force intercepts a great deal of it.

This is why this site sells none of them, and why any UK store that does is running a criminal enterprise however professional the checkout looks. If a shop is shipping trenbolone or testosterone to a UK address, someone is committing a fourteen year offence, and the customer list is that person’s evidence file.

The compounds covered include testosterone and all its esters, nandrolone, trenbolone, stanozolol, oxandrolone, methandienone, oxymetholone, boldenone, drostanolone and methenolone, alongside human growth hormone in most practical circumstances. Class C also covers ketamine and most benzodiazepines, which gives you a sense of where Parliament placed them.

Two things people routinely get wrong. Buying from an overseas website does not place you outside UK law, because importation with intent to supply is still importation. And a prescription changes everything: testosterone prescribed by a GMC registered doctor and dispensed by a registered pharmacy is entirely lawful, which is the whole basis of testosterone replacement therapy.

Comparison showing oral steroids carry liver toxicity from 17 alpha alkylation while injectables carry infection and sterility risk

Two failure modes dominate writing about anabolic steroid side effects. Public health pages list every possible harm at maximum severity, which readers who have already decided simply discount. Forums flatten everything into manageable inconvenience. Neither helps anyone make a real decision.

The cardiovascular picture deserves the most attention and gets the least. Anabolic steroid use suppresses HDL cholesterol substantially and raises LDL, and left ventricular changes are measurable in long term users. It is the effect most likely to matter in twenty years and least likely to be noticed now, because nothing hurts while it happens.

Gynaecomastia comes from aromatisation, the conversion of testosterone into oestrogen. Once glandular tissue forms it does not resolve on its own and surgery is the only reliable answer. That is why search volume for it is so high, and so full of regret.

Hair loss follows genetics more than dose. If male pattern baldness runs in your family, androgens accelerate what was already coming. If it does not, you will most likely keep your hair.

Suppression of natural production is universal, and the recovery timeline varies enormously. Some men return to baseline within months. Some never do and end up on testosterone replacement permanently, which is the outcome nobody plans for and a meaningful number of men arrive at.

Blood pressure, acne, mood and sleep disruption, fertility effects and liver strain from oral compounds all belong on the list. Our side effects guide covers each against the evidence, including the places where that evidence is genuinely thin.

Most supplements that disappoint are not fake. They are real ingredients at doses too small to do anything, sold at a price that assumes you will never check. Five things give it away.

A proprietary blend hides the doses. If the label gives one total for a blend of six ingredients, you cannot know how much of any single one you are getting. That is the point of the blend.

The dose is per serving, and a serving may be two scoops. A tub that looks generous on the front often halves once you read how many scoops a serving actually is.

Compare against the dose used in the research. Creatine monohydrate is 3g to 5g a day. Citrulline studies use 6g to 8g. Beta alanine works at 4g to 6g. Anything well under those figures is decoration on a label.

The form matters as much as the name. Magnesium oxide and magnesium bisglycinate are both sold as magnesium and behave very differently once you swallow them. The same is true of zinc and of iron.

Third party tested should mean a certificate you can read. A badge on a product page is not a test result. Ask which laboratory, which batch, and what they actually tested for.

We hold ourselves to the same list. Every dose on this site is printed in full, and where a figure comes from the manufacturer rather than an independent test, the product page says so. If a product will do very little for you, we would rather say that than take the sale. The creatine and protein pages show what that looks like in practice, and the guides go further.

Comparison of legal steroid supplement ingredients showing creatine, protein and certain vitamins carry authorised GB health claims while tribulus and most botanicals do not

The shop stocks legal sports nutrition and food supplements. Whey, isolate, casein and plant protein. Creatine monohydrate, Creapure and creatine HCL. Branched chain and essential amino acids, glutamine, L carnitine, beta alanine, electrolytes, multivitamins and minerals.

Alongside those we are building an own brand range covering natural testosterone support, oestrogen balance and post training recovery, formulated around zinc, magnesium, vitamin D3, ashwagandha, DIM, calcium D glucarate, milk thistle and fenugreek at doses that match the published research rather than a label claim.

We will not stock anabolic steroids, SARMs, prohormones, DHEA, melatonin, yohimbine, sibutramine, DMAA, DMHA, or anything else that is a prescription only medicine or banned in a food supplement in Great Britain. Several of these are sold openly by sites that look entirely legitimate, which is exactly why the list is worth writing down.

We will not describe a supplement as a legal steroid, or imply that anything here replicates an anabolic compound. The Advertising Standards Authority has ruled against that repeatedly, and a product marketed as achieving a medicinal effect can be reclassified by the MHRA as an unlicensed medicine. It is also simply untrue.

Every product page states the dose of every active ingredient. Where an ingredient carries an authorised health claim in Great Britain we use the authorised wording, so zinc contributes to the maintenance of normal testosterone levels in the blood and creatine increases physical performance in successive bursts of short term high intensity exercise. Where no claim is authorised, which covers most botanicals including ashwagandha, tongkat ali and DIM, we give you the extract ratio, the standardisation and the dose, and make no claim at all.

Comparison of the NHS and private routes to TRT in the UK showing the NHS is free but slower and private is faster but paid

Testosterone replacement is legal on prescription. We explain what the clinics charge, what bloodwork you need first, and what the NHS will and will not do, without selling you anything you cannot legally buy.

Getting TRT on the NHS is possible but slow, and the threshold is stricter than most men expect. You generally need two morning total testosterone readings below the reference range alongside symptoms, and many GPs will refer to endocrinology rather than treat directly.

Private clinics are faster and charge for the convenience. Expect an initial consultation and a full blood panel, then a monthly or quarterly fee covering medication and monitoring. Prices vary widely, and the cheapest option is rarely the one with the best monitoring, which is the part you are actually paying for.

Before any of it, get tested properly. Morning total testosterone taken twice, plus SHBG, free testosterone, LH, FSH, oestradiol, a full blood count and a lipid panel. Low testosterone symptoms overlap heavily with sleep debt, depression, thyroid dysfunction and simple undereating, and a great many men who feel exactly like a TRT candidate turn out to have something cheaper and easier to fix.

Health content here is reviewed by a named, qualified person and carries the date it was last checked. We cite the NHS, TALK TO FRANK, the MHRA and peer reviewed research. Where the evidence for an ingredient is thin or absent, the page says so plainly. That is the whole difference between this site and the rest of the category.

In practice that means naming who checked the page and when. It means citing the NHS, TALK TO FRANK, the MHRA and peer reviewed research rather than other blogs recycling each other. And it means stating that a botanical carries no authorised health claim on the same page where we are trying to sell you that botanical.

That last one costs us conversions. It is also the only reason a site in this category deserves to rank, and the only sound reason to believe anything else on it.

Everything here applies to orders delivered within the United Kingdom.

Dispatch. UK orders are dispatched on working days. Your estimated delivery date is shown at checkout before you pay, and the dispatch confirmation carries your tracking details. Estimates are estimates. If something is going to be late we will tell you rather than leave you wondering, and if a delay becomes unreasonable you can cancel and be refunded.

Returns. Change your mind and you can return an unopened supplement within 14 days for a refund, in line with the Consumer Contracts Regulations. For hygiene reasons we cannot take back opened supplements unless they are faulty, which is standard across the industry rather than us being difficult.

If something is wrong. If a product arrives faulty, damaged or not as described, email Contact@peakprotocol.co.uk. Under the Consumer Rights Act 2015 you are entitled to a repair, replacement or refund, and we are not going to make you argue for it.

The full detail sits on the shipping and returns page.

Common questions

What people ask before they trust a site like this

Possessing anabolic steroids in medicinal form for your own use is not an offence. Supplying them to anyone, possessing them with intent to supply, producing them and importing them by post or courier are offences carrying up to fourteen years and an unlimited fine. Anabolic steroids are Class C under the Misuse of Drugs Act 1971. The full detail is in our UK steroid law guide.

No. Any site shipping anabolic steroids to a UK address is supplying a controlled drug, wherever it is based. The only lawful route to testosterone is a prescription from a GMC registered doctor, dispensed by a registered pharmacy.

Products marketed as legal steroids are ordinary food supplements given names that imply otherwise. Some ingredients inside them have genuine evidence behind them, creatine most obviously. None of them replicate an anabolic steroid, and claiming they do breaches UK advertising rules.

Testosterone replacement therapy is prescribed testosterone for men with clinically low levels. It is entirely legal in the UK on prescription, whether through the NHS or a private clinic, and it is a completely different proposition to buying testosterone online.

Morning total testosterone taken twice, SHBG, free testosterone, LH, FSH, oestradiol, full blood count, a lipid panel, and liver and kidney function. Test before you change anything, so you have a baseline worth comparing against.

Bloodwork first, so you know where you stand rather than guessing. Sleep, calories and training volume matter more than any supplement. Zinc, magnesium, vitamin D3 and vitamin B6 all carry authorised claims relevant to hormonal activity, protein synthesis and fatigue. Anything sold as a post cycle therapy drug is a prescription only medicine and not something we will ever sell you.

No, and we never will. This site exists because the information layer around them is either frightening or dishonest, and because the legal supplement market deserves a seller that prints its doses.

One last thing worth stating outright, because it explains most of the choices on this site. We make less money when we tell you a product will not do much. We do it anyway, because the alternative is the model everyone else in this category already runs, and you can see how much trust that has bought them.

If you are researching anabolic steroids, you will find pages here that explain how they work, what they do to blood pressure and cholesterol and fertility, and what the law says about possession against supply. None of that is an endorsement and none of it is a sales pitch. It is information that already exists in the medical literature, written in a form you can actually use, because people are going to make these decisions with or without accurate information and the version with accurate information goes better.

If you are looking for legal supplements, the shop sells them with the doses printed and the claims kept inside what is authorised in Great Britain. If you want the legal route to testosterone, the TRT guides explain how it works without selling you anything you cannot lawfully buy.
