Every iMuscle listing compared
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 one of the third-party brands sold through Muscle Market alongside our own Free Muscle range. This collection lists every iMuscle product we currently stock. It is the widest SARM selection of any single brand on the site: seven single-compound capsule listings with a stated strength per capsule, plus five multi-compound packs. Every pack in our data contains 60 capsules. Each compound also has its own collection page where iMuscle can be compared with the other brands we hold.
What is in the iMuscle range

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 manufacturer, so its batches are not covered by the Janoshik Analytical programme that tests every Free Muscle batch. For iMuscle products, a certificate of analysis is shown only where the manufacturer supplies one for the specific batch we hold; where none is available, the listing does not claim one. A usable certificate names the batch, confirms the identity of the compound and states the measured purity. A generic PDF without a batch number is not a batch certificate. See our lab tests page for what is provided per brand.
Legal status in the UK
None of these compounds is a licensed medicine. None has been assessed by the MHRA, and none is an authorised food supplement. They are supplied to adults aged 18 or over for laboratory research only and are not for human consumption. SARMs (YK-11, RAD-140, S-23, Ostarine, LGD-4033, Andarine), the growth hormone secretagogue MK-677 and the metabolic modulators SR-9009 and Cardarine are all prohibited in sport under the World Anti-Doping Agency list. Our SARMs research guide covers the class in more depth.
Delivery and returns
Every order ships with free tracked UK delivery in plain packaging. Orders placed before 2pm Monday to Friday are processed the same working day. EU delivery takes 3 to 7 working days. Unopened items can be returned within 30 days. Full details are on our shipping page and guarantee page. Customers must be 18 or over.

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 provide a certificate of analysis for each batch?
Only where the manufacturer supplies one for the batch we hold. iMuscle batches are not part of the Janoshik Analytical testing that covers the Free Muscle brand, so a certificate cannot be promised for every pack. Where one is available it is shown on the listing, and it should carry the batch number, compound identity and measured purity.
What is the difference between RAD-140, LGD-4033 and Ostarine?
All three are non-steroidal SARMs that bind the androgen receptor, but they differ in chemical structure, binding affinity and the depth of published human data. Ostarine progressed furthest, reaching late-stage clinical trials without gaining approval; LGD-4033 was studied in early-phase trials that were not taken further; RAD-140 has the least human data, limited to a small early-phase trial. iMuscle supplies them at 15 mg, 8 mg and 10 mg per capsule respectively, for research only.
What is in an iMuscle combination pack?
Each combination listing names the compounds the manufacturer has packed together, for example Ligandrol, Testolone and YK-11, in a 60-capsule pack. The per-compound content is whatever the individual listing states. The combination is how the product is supplied; it is not a protocol recommendation, and we do not advise on selection or use.
How are iMuscle orders shipped and can they be returned?
Orders ship with free tracked UK delivery in plain packaging. Orders placed before 2pm Monday to Friday are dispatched the same working day, and EU delivery takes 3 to 7 working days. Unopened items may be returned within 30 days under our guarantee; opened research materials cannot be accepted back. Buyers must be 18 or over.
