Everything Free Muscle sells: own-brand research compounds batch-tested by Janoshik, Muscle Market brands, creatine, pre-workout and gym apparel. 18+.
This page lists everything Free Muscle sells: own-label research compounds in capsule form, the Bioreactive Series, two performance nutrition food supplements, gym apparel, and, through Muscle Market, research compounds from four other brands. The categories have different rules. Research compounds are sold to adults for laboratory study and are not for human consumption. Creatine and pre-workout are food supplements. Apparel is apparel. Every Free Muscle-brand batch is assayed by Janoshik Analytical, an independent laboratory, with the certificate available on request.

Muscle Market brands
Alongside our own label we list research compounds from iMuscle, Yakka Strength, Thoroughbred Labs and BioLab, which adds LGD-4033, Ostarine, Andarine, S-23, SR9009, BPC-157, SLU-PP-332 and 5-Amino-1MQ to the range. Each compound page shows every brand side by side so you can compare strength, pack size and batch testing.
How to compare listings
For research compounds, multiply milligrams per capsule by capsules per pack, work out the price per milligram, and ask for the batch certificate. For food supplements, read the ingredient panel and per-serving quantities. Our price per milligram article shows the working.
Batch testing and certificates of analysis
A certificate of analysis states what an independent laboratory identified in a specific batch and the purity it measured. Every Free Muscle-brand batch goes to Janoshik Analytical, and the batch number is printed on the pack; email us the number and we will send the certificate. For iMuscle, Yakka Strength, Thoroughbred Labs and BioLab, a certificate is shown only where the manufacturer supplies one for the batch we hold. A generic PDF with no batch number is not a batch certificate. See how we test.
Legal status in the UK
None of the research compounds is a licensed medicine (MHRA) or an authorised food supplement. They are sold to adults for laboratory research only and are not for human consumption. Most are prohibited at all times under the WADA list. Creatren and NitraGlyc are food supplements and should not replace a varied diet. Our SARMs research guide explains the legal position in more detail.

Frequently asked questions
Is everything on this site a research compound?
No. The catalogue has three kinds of product. Research compounds such as SARMs, peptides and MK-677 are sold to adults for laboratory research and are not for human consumption. Creatren and NitraGlyc are food supplements. The merch range is gym apparel. Each product page states which category it belongs to, and the rules for each are different.
Which brands does Free Muscle stock?
Our own Free Muscle label, which includes the Bioreactive Series and every batch of which is assayed by Janoshik Analytical, plus four Muscle Market brands: iMuscle, Yakka Strength, Thoroughbred Labs and BioLab. For those brands we show a certificate only where the manufacturer supplies one for the batch we hold. Each compound page lists every brand side by side.
How do I verify a batch?
For Free Muscle-brand products, email us the batch number printed on the pack and we will send the Janoshik Analytical certificate for that batch, which records the compound identified and the purity measured. Match the batch number to your pack. For other brands, check the product page for a manufacturer certificate covering the batch we hold; if none is shown, none was supplied.
Do you ship outside the UK?
Yes. Every order ships free with tracking inside the UK in plain packaging, and EU delivery takes 3 to 7 working days. Orders placed before 2pm Monday to Friday are processed the same working day. Import rules for research compounds differ by country, so check the law where you live before ordering. Our shipping page has the full details.
Can I return a product?
Unopened items can be returned within 30 days of delivery. Opened research compounds and opened food supplements cannot be resold, so they cannot be returned unless faulty. If anything arrives damaged or incorrect, contact us with your order number and we will resolve it. The guarantee page sets out the full policy.
