Frequently asked questions
Which brands can I compare on Muscle Market?
Free Muscle, our own brand, and four partner brands: BioLab, iMuscle, Thoroughbred Labs and Yakka Strength. Each brand has its own page, and each compound page lists every brand we stock side by side with strength, pack size, price per capsule and price per milligram.
Can I order several brands in one basket?
Yes. Every brand on Muscle Market goes into the same basket and the same checkout, and the order is sent as one parcel from our UK stock. UK delivery is free and tracked on every order, with no minimum spend, and usually arrives 2-3 working days after dispatch.
Is every brand batch-tested?
Every Free Muscle-brand batch is assayed by Janoshik Analytical, and we send the certificate for your batch on request. For BioLab, iMuscle, Thoroughbred Labs and Yakka Strength, a certificate is shown where the brand supplies one for the batch we hold; each brand page explains what that brand publishes and how to check a pot.
Do you deliver Muscle Market orders to Romania and 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 a Muscle Market order?
Yes: unopened items can be returned within 30 days, whichever brand they are from. Our guarantee page has the full policy. Research compounds on Muscle Market are sold for laboratory research use only, not for human consumption, to adults aged 18 or over.
