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 trading name of FreeMuscle, a business registered in Andorra, with UK operations and dispatch 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 a multi-compound pack. 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.
- MK-777 (Acetamoren), part of the Bioreactive Series: MK-777 Bioreactive Series. Compound page: MK-777.

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.
Where to buy Free Muscle products in the UK: how to check a supplier
Whichever shop you buy Free Muscle products 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. Every Free Muscle-brand batch is assayed by Janoshik Analytical, and we send the certificate for your batch on request.
- 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 Free Muscle research compound is sold; CREATREN and NitraGlyc on this page are food supplements, and the rest of the range is gym apparel.
- 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: iMuscle, BioLab, Thoroughbred Labs and Yakka Strength. Compare them side by side in the Muscle Market.
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.

Research compounds sold by Free Muscle are supplied for laboratory research use only and are not for human consumption. They are not authorised as medicines by the MHRA, EMA or FDA, are not food supplements, and are sold only to adults aged 18 or over. Nothing on this page is medical or dosing advice.
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.
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.
Is there a discount when I buy more than one?
Yes, on Free Muscle-brand products: 5% off automatically when your cart holds 2 of them and 10% off with 3 or more, applied in the cart. MK-677 25mg also has a buy 2, get 1 free offer. The offers do not combine. Apparel and the Bioreactive Bundle are not part of the offer.
