Muscle Research: supplement stacks, single bottles and a free shipping code

Shopping at Muscle Research? See all current Muscle Research discount codes and deals, checked regularly.

Muscle Research is an online shop run by Muscle Research Limited, a company registered in London in 2018. It sells its own range of food supplements in capsule form, aimed at people who train with weights, and sorts them into bulking, cutting and stacks sections. Prices are in pounds, and the shop says it delivers worldwide with tracking.

The site says its products are not for anyone aged 18 or under, and that its statements haven't been evaluated by the Food Standards Agency. We're not making any claims about what the products do: this is a look at the range, prices and how buying works. Speak to your GP or pharmacist if you have any concerns about your health.

What's worth a look

• D-Bol: one of the shop's single bottles, currently £49.99 (was £59.99).
• Test 500: another single product at the same price, currently £49.99. Most singles in the range share this price, which makes comparing them simple.
• Growth Stack: four products sold together as a 30-day set, currently £149.99 against a listed £199.96. At the time of writing it was on pre-order, with shipping due at the end of October.
• Genotrope pGH: the most expensive single item in the range, currently £99.99 (was £130.00).
• Ultimate Stack: a bundle of the shop's base single products, for anyone who wants the full range in one order.

Stack pages carry notes about stock and pre-orders, so read them before you order to see when your parcel is likely to leave.

Questions about orders go through the contact form or by email to the address on the contact page, with replies promised within 24 to 48 hours. The site also runs a blog and a coaching service, and you'll need to be over 18 to buy, as the shop says its products are not for anyone aged 18 or under. If you're unsure whether a product suits you, read the ingredients on the product page and check with a professional before ordering.
