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.

Free Muscle is the house brand of FreeMuscle LTD, a UK company based in Scunthorpe. This collection lists every Free Muscle-brand research compound we currently stock. All of them are supplied in capsule form, and each listing states the compound, the strength per capsule where applicable and the number of capsules per pack. What sets the range apart from the other brands on Muscle Market is testing: every Free Muscle batch is assayed by Janoshik Analytical, an independent laboratory, before it is sold.
What is in the Free Muscle range
The range covers growth hormone secretagogues, SARMs, a PPAR-delta agonist, a selective oestrogen receptor modulator, a peptide-class compound and two multi-compound packs. Each compound also has its own collection page.
- MK-677 (ibutamoren) in three strengths, each 60 capsules: 10 mg, 12.5 mg and 25 mg. See all brands on the MK-677 collection.

How to compare listings
Where a strength is stated, multiply it by the capsule count to get the total milligrams in the pack, then compare the cost per milligram against the same compound from another brand. Our article on price per milligram walks through the arithmetic. Strength and pack size are product facts, not a recommendation.
Batch testing and certificates of analysis
Every Free Muscle batch is sent to Janoshik Analytical for independent assay before release. The resulting certificate of analysis records the identity of the compound and its measured purity for that specific batch. To receive the certificate for the batch you hold, email us with the batch number printed on the pack. A generic PDF with no batch number is not a batch certificate; our lab tests page explains what to look for. This is the main difference from the other brands on Muscle Market, where a certificate is shown only when the manufacturer supplies one for the batch held.
Legal status in the UK
No product in this collection is a licensed medicine. None has been assessed by the MHRA for safety, quality or efficacy, 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. In sport, the compounds in this range are prohibited under the World Anti-Doping Agency list, either by name (the SARM RAD-140, the metabolic modulator GW-501516 and the growth hormone secretagogue MK-677) or by category (selective oestrogen receptor modulators such as enclomiphene, and substances with no current approval for human use). Background on the SARM class is in our SARMs research guide.
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
Is every Free Muscle product batch-tested?
Yes. Every batch of a Free Muscle-brand product is assayed by Janoshik Analytical, an independent laboratory, before it goes on sale. The certificate of analysis for the batch you hold is sent on request by email; quote the batch number printed on the pack. Other brands sold on Muscle Market show a certificate only where the manufacturer supplies one for that batch.
Are Free Muscle products legal to buy in the UK?
The compounds in this range are not licensed medicines and are not authorised food supplements. They are sold in the UK to adults aged 18 or over for laboratory research purposes only and are not for human consumption. Most are prohibited in sport under the World Anti-Doping Agency list, so anyone subject to testing should treat them as banned.
Which strength of MK-677 should I choose?
We do not advise on strength selection. The 10 mg, 12.5 mg and 25 mg listings exist so that research buyers can select the concentration their protocol calls for, and the total milligrams per pack is the strength multiplied by 60 capsules. All three are sold for laboratory research only and nothing on this site is dosing guidance.
How are Free Muscle orders shipped?
Every order ships with free tracked delivery within the UK in plain packaging. Orders placed before 2pm Monday to Friday are dispatched the same working day. EU orders typically arrive within 3 to 7 working days. Full details, including how tracking works, are on the shipping page, and buyers must be 18 or over.
Can I return a Free Muscle product?
Unopened items can be returned within 30 days of delivery under our returns policy. Because the products are sold as research materials, opened packs cannot be accepted back. Details of how to raise a return are on the guarantee page, and any question about an order can be sent to us by email.
