Strength and pack size as stated by each manufacturer. Total milligrams = strength per capsule multiplied by capsules per pack. Price per milligram is calculated from the current price. A dash means the manufacturer does not state that figure.

iMuscle is a SARMs brand that sells capsules through its own country websites in Europe, among them a Romanian-language shop at imuscle.ro, and describes itself as an international online shop for SARMs. It is one of the third-party brands in our Muscle Market range. This page lists all 17 iMuscle products Free Muscle stocks: the nine single-compound pots of the brand's standard line and eight stacks that pair or group those compounds. Each compound also has its own collection page, where iMuscle can be set beside the other brands we hold. Every listing here is offered to adults of 18 or over, for laboratory research alone.
About iMuscle
What can be checked about iMuscle comes from its own websites and packaging, read in October 2026:
- Where it sells. A Romanian-language shop at imuscle.ro, whose product pages link sister shops for Spain, France, Italy, the Netherlands, Slovakia and Greece. Its About page lists ten countries where its products are available, the United Kingdom among them.
- How it describes itself. In its own words, an international online SARMs shop. The About page divides the range into a standard line of nine single-compound products and a combined series, VENOM, HULKED, COMBAT and MACHINE, in which several compounds share a capsule.
- What it says about testing. iMuscle states that, because SARMs are unregulated, it has every lot tested at an independent European laboratory, and its quality page says incoming raw material must reach at least 97% purity. These are the brand's own statements, not results we have checked.
- How it labels strength. Each pot is black with a colour-coded label, the iMUSCLE logo at the top and a box giving the capsule count and milligrams per capsule. The brand's shop writes the same figures as capsules over milligrams, for example 60/15mg, and for all nine singles they match our listings.
Some things could not be verified. iMuscle's websites do not say where the business is registered or who runs it, we found no official social media accounts, and we could not match the brand to an active company on the UK register at Companies House. None of the pages we read names a UK stockist, so Free Muscle does not describe itself as an official, authorised or exclusive seller of the brand.
What is in the iMuscle range
All nine single-compound pots of iMuscle's standard line are stocked, each 60 capsules with the strength printed on the label. The name printed largest on the pot is not always the compound name:
| Compound | Name on the iMuscle pot | Stated strength | Listing |
|---|---|---|---|
| Andarine (S-4) | ANDARINE S4 | 15 mg x 60 | iMuscle Andarine S-4 |
| Cardarine (GW-501516) | CARDARINE | 10 mg x 60 | iMuscle Cardarine GW-501516 |
| MK-677 (ibutamoren) | IBUTAMOREN | 10 mg x 60 | iMuscle Ibutamoren MK-677 |
| LGD-4033 (ligandrol) | LIGANDROL | 8 mg x 60 | iMuscle Ligandrol LGD-4033 |
| Ostarine (MK-2866) | OSTABOLON | 15 mg x 60 | iMuscle Ostarine MK-2866 |
| RAD-140 (testolone) | TESTOLON | 10 mg x 60 | iMuscle Testolone RAD-140 |
| S-23 | S-23 | 15 mg x 60 | iMuscle S-23 |
| SR9009 | STENABOLIC | 10 mg x 60 | iMuscle Stenabolic SR-9009 |
| YK-11 | YK 11 | 10 mg x 60 | iMuscle YK-11 |
The eight stacks offer two or three of those compounds in one listing, as iMuscle does on its own shop. Their photographs show a separate labelled pot for each compound; ask us to confirm the contents of the stock held before ordering. A stack is how the products are offered for sale, not a suggestion that they be studied together:
- Cardarine and Ligandrol
- Cardarine and Ostarine
- Cardarine and Testolon (RAD-140)
- Cardarine, Ibutamoren and Andarine
- Ostarine, Andarine and Cardarine
- Ligandrol, Ibutamoren and Ostarine
- Ligandrol, Testolon and YK-11
- Testolon, YK-11 and Ibutamoren
Not stocked: iMuscle's combined series (VENOM, HULKED, COMBAT and MACHINE) and the brand's products outside its standard line.
All combination packs across brands are grouped under Bundles and Stacks.
How to compare listings
For a single-compound pack, multiply the stated strength by 60 to get the total milligrams, then work out the cost per milligram and set it against the same compound from another brand. The price per milligram article shows the method. Multi-compound packs cannot be compared this way unless the per-compound content is stated on the listing.
Batch testing and certificates of analysis
iMuscle is a third-party brand, so its products are outside the Janoshik Analytical programme that tests every Free Muscle batch. For iMuscle, a certificate of analysis is shown only where the manufacturer supplies one for the batch we hold. Eight of the nine single listings show two documents in their galleries: a Bulgarian-language test protocol from a laboratory in Sofia that names iMuscle LTD. as manufacturer and reports an HPLC assay of one sample, and an English HPLC print-out with a lot number. All of them date from 2021 and the protocols carry no lot number, so they record earlier tests rather than the pots in stock now. The Cardarine single and the eight stacks show no document. See our lab tests page for what is provided per brand.
How to check an iMuscle batch
- Find the lot code. It is not visible in the product photographs, so look on the label, base and cap of the pot itself.
- Match it to the document. A certificate speaks only for the lot whose number it carries; a document with no lot number, or a different one, describes another run.
- Read what was measured. Look for the compound named on the label and, ideally, the content per capsule as well as purity. A purity percentage alone does not confirm the milligram figure.
- Ask us with the code. Use the contact page, give the product and its lot code, and we will send any document iMuscle has supplied for that lot or tell you that there is none.
Reading the fields of a COA is explained in our piece, how to read a certificate of analysis; the UK supplier checklist applies the same tests to any seller.
Where to buy iMuscle in the UK: how to check a supplier
Whichever shop you buy iMuscle from, check these five points before you order:
- A batch number and a certificate for that batch. The pack should carry a batch number, and the seller should be able to show a certificate of analysis for that same batch from a named laboratory, with the test date. For iMuscle, a certificate is shown where the brand supplies one for the batch we hold.
- The strength per capsule and the capsule count. With both figures you can work out the total milligrams in the pack and the price per milligram; the comparison table above does this for every listing here that states both. If a listing does not state one of them, ask the seller before you order.
- Research-use labelling and an age check. A research compound should be sold for laboratory research use only, not for human consumption, to adults aged 18 or over, with no dosing or usage advice. That is how every listing here is sold.
- Prices in pounds sterling and tracked UK dispatch. UK delivery from us is free and tracked on every order, with no minimum spend, and usually arrives 2-3 working days after dispatch; orders placed before 2pm Monday to Friday are processed the same working day.
- A clear returns policy. Unopened items can be returned to us within 30 days.
Other brands we stock: Free Muscle, BioLab, Thoroughbred Labs and Yakka Strength. Compare them side by side in the Muscle Market.

Research compounds sold by Free Muscle are supplied for laboratory research use only and are not for human consumption.

Frequently asked questions
Are iMuscle SARMs legal in the UK?
SARMs are not licensed medicines in the UK and are not authorised food supplements. The iMuscle listings here are sold to adults aged 18 or over for laboratory research only and are not for human consumption. All SARMs, along with MK-677, SR-9009 and Cardarine, are prohibited in sport under the World Anti-Doping Agency list at all times.
Does iMuscle test its products?
iMuscle says it does: its website states that every lot goes to an independent European laboratory and that incoming raw material is held to a 97% purity minimum. Those are the brand's claims. The papers on our single listings are from 2021, and the protocols lack a lot number, so they say nothing about current stock. iMuscle is outside the Janoshik testing that covers Free Muscle's own brand; a certificate is displayed only when iMuscle has sent us a document for the stock we hold.
Is iMuscle legit?
We can only point to what can be checked. iMuscle runs its own shops in several European countries, its pot labels state strength and capsule count, and those figures match our listings. Its test documents on our site are from 2021, and we found no company register entry or independent reviews to cite. Judge a pot by its lot code and any certificate for that lot, which you can request from us before ordering.
What is in an iMuscle stack?
Each stack listing names the compounds iMuscle offers together, such as Ligandrol, Testolon and YK-11, and each listing's photographs show one labelled pot per compound. Before ordering, please check with us what the stock held contains. A stack is a way of selling the products, not a suggestion that they be used or studied together, and it differs from iMuscle's combined capsules, which we do not stock.
Where is iMuscle based?
iMuscle does not say where it is registered. It sells through separate country websites, one of them in Romanian, and names ten countries, the UK included, where its products can be bought. The test protocols in our product galleries come from a laboratory in Bulgaria and name iMuscle LTD. as manufacturer, but we could not match that name to an active UK company, so we state no location for the brand.
Is Free Muscle an official iMuscle stockist?
No such status is claimed. Free Muscle stocks iMuscle products alongside its own brand and the other Muscle Market brands, but iMuscle's websites name no UK stockists on the pages we checked, so we describe ourselves only as a seller of the brand. Orders are placed with FreeMuscle, a business registered in Andorra, and ship from Scunthorpe with free tracked UK delivery in plain packaging.
Do you stock iMuscle HULKED, VENOM, COMBAT or MACHINE?
No. Those belong to iMuscle's combined series, in which each capsule holds more than one compound, and none of them is listed on Free Muscle. What we do stock is the standard line of nine single pots plus eight stacks built from them, every one linked from this page.
Where can I buy iMuscle in the UK?
Free Muscle lists the iMuscle products on this page and ships them from the UK, with free tracked delivery on every UK order, usually 2-3 working days after dispatch. We describe ourselves only as a seller of the brand, not as an official stockist. Supplied for laboratory research use only, not for human consumption, to adults aged 18 or over.
How can I check that the iMuscle pot I receive is genuine?
Find the lot code on the label, base or cap of the pot; it is not visible in the product photographs. A certificate speaks only for the lot whose number it carries, so match the two, and look for the compound named on the label and, ideally, the content per capsule as well as purity. Send us the product name and the lot code and we will send any document iMuscle has supplied for that lot, or tell you that there is none.
How fast is UK delivery?
UK delivery is free and tracked on every order, with no minimum spend, and usually arrives 2-3 working days after dispatch. Faster tracked UK delivery costs £6 and usually takes 1-2 working days. Orders placed before 2pm Monday to Friday are processed the same working day.
Do you deliver to Romania and the rest of the EU?
Yes. Orders to Romania and other EU countries travel by our paid, tracked international service and usually arrive 3-7 working days after dispatch; delivery to the rest of the world usually takes 5-14 working days. Prices are in pounds sterling (GBP). Rules differ in other countries, so check local law before ordering for delivery abroad.
Can I return an order?
Yes: unopened items can be returned within 30 days. Our guarantee page has the full policy.
