About Muscle Research
Muscle Research is an online supplement shop run by Muscle Research Limited, a company registered in London in 2018. It sells its own range of food supplements for people who train with weights, in capsule form, grouped into bulking, cutting and stacks sections.
Single products such as D-Bol, Test 500 and Deca 300 sit alongside four-product stacks and a product called Genotrope pGH. At the time of writing, stacks were listed as buy one get one free and some were on pre-order. The site states that its products are not for anyone aged 18 or under and that its statements have not been evaluated by the Food Standards Agency. A coaching service and a blog are also offered.
Prices are in pounds. The shop says it ships worldwide with tracked delivery, and prints a free shipping code on its homepage banner. Unused, unopened products can be returned within 30 days for a full refund. Support is by email through its contact page. Speak to your GP or pharmacist if you have any concerns about your health.
