Shop

Everything here is a food supplement. These are legal supplements UK customers can buy without a prescription, from a shop that prints the dose on every page and keeps its claims inside what is actually authorised. We do not sell anabolic steroids, and we never will.

That last sentence is the whole positioning. A large part of this market sells products named to resemble controlled substances and priced as though they behave like them. Nothing in this range does, nothing legally sold in Britain does, and every product page here says so where it applies.

What the legal supplements UK range actually covers

Thirteen categories, one hundred and five legal supplements, and every one of them a food supplement rather than anything requiring a prescription. The range is built around a simple split: the handful of things with genuine evidence behind them, and the things people ask for, which we stock while being honest about what the research says.

Thirty eight products are our own label and sixty seven come from twenty two other companies we do not own and are perfectly willing to criticise. That mix of legal supplements is deliberate, and the reasoning is set out on our supplement brands page.

The short list of things that actually work

The first group is short, and it is worth stating before anything else on this page tries to sell you something. Creatine and protein both carry authorised health claims in Great Britain, which very few legal supplements do. Vitamin D is the deficiency that genuinely affects most British adults through winter. Beta alanine has good evidence in a narrow window of one to four minute efforts. That is most of what works, and it is all inexpensive.

Everything in the legal supplements range beyond that list is optional in a way those four are not. Some of it is well made and pleasant to use. Some of it is bought on a mechanism that sounds convincing and has never produced an effect in a controlled trial. Our guide to which legal supplements have real evidence goes through the category by category version of that argument, and it is the most useful twenty minutes you can spend before buying legal supplements anywhere.

If you are starting from nothing, the honest order is protein first if your diet is short, then creatine, then vitamin D through the winter. That costs under fifty pounds a month and captures most of the benefit available from legal supplements. The NHS guidance on vitamins and minerals covers the same ground for the third of those and costs nothing to read.

How the legal supplements UK pricing works

Own brand legal supplements skip the licensing and marketing costs, so you pay for the ingredient rather than the name. Branded products carry a premium that buys a longer track record and, at the larger manufacturers, deeper quality control. Both are legitimate purchases and we say plainly on each product page which one you are making.

Every product page prints the specification and compares cost per serving rather than cost per tub, because serving sizes across legal supplements are set by whoever made the product and a headline price tells you very little on its own. A cheap tub with a small scoop and an expensive tub with a large one can cost exactly the same to use for a month.

For a single ingredient, go one step further and compare cost per gram of the active. A creatine at twenty pounds for five hundred grams and one at fifty pounds for two hundred grams are not close, whatever the front of the tub says. That test is why the cheapest creatine in this shop is also the best evidenced form of it.

Own label against the imported brands

Our own label legal supplements exist because there were gaps we could not fill from other ranges at a price we thought was fair. Twenty four of the thirty eight own label products contain a single active at a stated dose, which makes them easy to compare against anything else on the market and impossible to hide behind a proprietary blend.

The imported legal supplements are here because some brands make things we do not, and some make a specific product better than we would at the price. Where a competitor product on this site is the better buy for what you are trying to do, the product page usually says so. We would rather sell you the right tub once than the wrong tub twice.

What may lawfully be claimed on any of this

Every one of these legal supplements is a food supplement under UK law rather than a medicine, and that distinction sets what anyone is allowed to say about it. Only wording on the Great Britain nutrition and health claims register may be used, and only where the product actually delivers the required amount of the nutrient. The Food Standards Agency guidance for food supplement businesses explains how that works, and the food labelling rules govern what has to appear on the pack.

In practice that means a page here may tell you zinc contributes to the maintenance of normal testosterone levels, because that claim is authorised and the product hits the threshold. It may not tell you zinc boosts testosterone, because that is a different statement and it is not authorised for anything. When a competitor tells you a mineral boosts anything, they are either outside the register or relying on nobody checking.

Competitive athletes have a separate problem that no amount of label reading solves. Legal supplements being legal is not the same as a batch being clean, because contamination happens at the manufacturing level. UK Anti-Doping publishes guidance on supplement use, and if you are tested you should be checking the batch rather than trusting the brand.

What we will not sell

Peak Protocol does not sell, supply or source anabolic steroids, SARMs, or anything else requiring a prescription. Our legal supplements UK range is exactly that, and the guides covering controlled substances exist because people search for honest information, not because we have anything to sell them at the end of it.

We also do not describe these legal supplements as legal steroids or steroid alternatives. That phrasing is misleading about what the product does and it sits outside UK advertising rules, which is why you will find it on a great many competitor sites and none of our product pages. Our guides on where UK law sits and the Misuse of Drugs Act 1971 cover the category we deliberately stay out of.

There is no fat burner in the range either, for the simple reason that legal supplements cannot produce meaningful fat loss and selling one implies that they can.

How to choose well here

Four checks, in order, and they take about a minute each.

Read the serving size before the price. Everything else on the label is quoted against it, and it is the single number that makes two products comparable.

Look for the active early in the ingredient list. Ingredients are declared by weight, so position tells you roughly how much is in there even when the amount is not stated.

Avoid proprietary blends. A blend exists to stop you seeing how little of each named ingredient is present. There are none in our own range and we flag them where they appear in an imported one.

Check what you already take. Duplication is the commonest waste across legal supplements. Three products can each contain zinc and between them push you well past what any of them intended on its own.

How to read a supplement label in one minute

With legal supplements, most of what separates a good purchase from a bad one is visible on the back of the pack before you buy. Four things are worth finding, in this order.

The amount per serving, not per hundred grams. Manufacturers quote whichever figure flatters the product. Per serving is what you will actually take, and it is the only number that compares across two tubs with different scoop sizes.

The form of the mineral, not just its name. Zinc picolinate and zinc oxide are both zinc on the front of the pack and behave very differently once swallowed. The same is true of magnesium bisglycinate against magnesium oxide, which is the usual reason people conclude magnesium upsets their stomach.

Where the active sits in the ingredient list. Ingredients are declared in descending order by weight. An active listed after the flavouring and the anti caking agent is present in a token amount, whatever the front of the pack implies.

The allergen line. Whey declares milk. Blended plant proteins frequently declare soy through the lecithin used as an emulsifier. Hydrolysed whey still declares milk, because hydrolysis shortens the protein chains without removing the source.

Those four checks catch nearly everything that matters, and they work on legal supplements from any brand in any shop rather than only on this one.

Why a shop publishes guides about things it does not sell

Roughly half of what we publish covers compounds we will never stock: anabolic steroids, SARMs, and the clinical question of testosterone replacement. That looks odd for a retailer and there is a straightforward reason for it.

People search for this material either way. The alternative to accurate information is not silence, it is the information they would otherwise find, which is split between sites committed to selling them a controlled substance and sites written to frighten. Neither is useful to somebody making a real decision, and the second kind does more harm than it prevents, because it closes the tab and sends the reader back to a forum.

So the guides cover what the law actually says, including the parts people get wrong, such as the fact that possession for personal use and supply are treated completely differently. They cover side effects from the evidence rather than the anecdotes. They cover harm reduction, because people make these decisions with or without accurate information and the version with it goes better. What they never contain is a dose, a protocol or a source, and that line is deliberate.

The commercial consequence is that a reader arrives for a guide about something we do not sell, and either buys nothing or buys a twenty pound tub of creatine. That is a worse funnel than the one our competitors run and a considerably better business over five years. Our editorial policy sets out the rules the guides are written to, and our experts covers who writes them and what review is still outstanding.

Delivery, payment and returns

All of these legal supplements ship from UK stock, so there is no customs charge and no wait on a European dispatch. Orders placed before the afternoon cut off go out the same working day, tracked as standard, in plain outer packaging with an unremarkable billing descriptor.

Payment works differently here from most shops and it is worth reading before you order: nothing is charged at checkout, and the payment details come from our support team against your order number rather than being published on the site. How to pay explains why, in full.

Unopened legal supplements can be returned within fourteen days under the Consumer Contracts Regulations. Opened supplements cannot, for hygiene reasons that apply across the industry. If something arrives faulty or does not arrive, that is ours to fix. Shipping and returns sets out exactly where you stand.

Common questions about the shop

Are these legal supplements UK regulated?

They are regulated as food rather than as medicines, which is a lower bar than a licensed drug and a real framework nonetheless. Composition, labelling and permitted claims are all governed, and the Food Standards Agency oversees the sector.

Do you sell anabolic steroids or SARMs?

No, and we never will. Both sit outside what a food supplement retailer may lawfully sell in the UK. The guides covering them are information, not a catalogue.

Why do some product pages talk the product down?

Because the evidence behind some categories is thin, and a page that hides that is selling you something you will not repurchase. We would rather lose one sale than lose the reader.

What is the cheapest useful thing to buy?

Creatine monohydrate. Around twelve to twenty pounds for five hundred grams, which is roughly a hundred servings, from the single best evidenced product in sports nutrition.

Do you ship outside the UK?

Orders are handled for delivery within the United Kingdom. Everything on the shipping page applies to UK addresses.

How do I know the dose is really what the page says?

You do not, from a page alone, and that is true of every supplement retailer. What we control is that the figure printed is the figure the manufacturer declares, and that where we cannot verify a number we say so rather than repeating it.

How should I store what I buy?

Dry and sealed covers almost all of it. Creatine is stable as a powder and degrades once mixed, so make each serving fresh. Omega 3 oxidises with heat and light, which is why a fish oil that tastes strongly of fish has usually gone off. Electrolyte powders pull moisture out of humid air and clump, which is a storage symptom rather than a fault. Capsules belong in a cupboard rather than on a windowsill.

Do any of these legal supplements interact with medication?

Some can, and a product page is not the place to settle that. Anything you take alongside a prescription is a question for the prescriber or a pharmacist, who can see the whole list rather than one item from it. That applies as much to a multivitamin as to a botanical extract, and it is the single most common reason to ask before buying rather than after.

Browse by category above, or start with creatine and protein, which are the two categories where the evidence is strongest and the prices lowest. If you would rather read first, the guide library covers UK law, testosterone and blood work in full.
