More about SARMs Store
The range covers the compounds that appear most often in the published literature. Ostarine (MK-2866) is the most studied, with phase II and phase III trial data. Ligandrol (LGD-4033) and Testolone (RAD-140) reached phase I. Ibutamoren (MK-677) is a growth hormone secretagogue rather than a SARM, studied in older adults for two years. Cardarine (GW-501516) and Stenabolic (SR-9009) act on metabolic pathways rather than the androgen receptor. Andarine (S-4), YK-11, S-23, ACP-105 and TLB-150 are preclinical compounds with animal or cell data only. Combined formulations are listed under research stacks.
Each product page states the strength per capsule, the capsule count, the batch number format and a plain summary of what the published studies measured, what they did not, and where the compound stands in UK law. Our SARMs 101 guide explains how the compounds differ, and the Batch testing page explains how to match a bottle to its certificate of analysis. Independent batch certificates of analysis are being commissioned and will be published as each batch is tested.
Orders are dispatched the same working day when placed before 2 pm, by tracked delivery, free in the UK over £60. The compounds and their stated strengths have not changed. Research use only. 18+.
