Is S-23 legal in the UK in 2026? SARMs are not controlled substances under the Misuse of Drugs Act 1971, so buying and possessing S-23 as a research chemical is lawful in the United Kingdom in 2026. What is not lawful is selling or advertising it for human use, because the MHRA treats it as an unlicensed medicine in that context. That is why this listing, and every listing on this site, is worded for laboratory research and nothing else.

How fast is delivery? We despatch UK orders the same working day by tracked delivery, usually arriving within two to three working days, with a next day upgrade available at checkout, in discreet plain packaging that carries no product or compound name on the outer label. International shipping is offered to most countries, subject to a restricted destination list shown at checkout where local import rules apply.

How should the capsules be stored? Keep the bottle sealed in a cool, dry place below 25C and out of direct sunlight. Stored that way the capsules remain stable for the shelf life printed on the label. Avoid humid environments such as bathrooms and kitchens, because moisture is the main cause of degradation in capsule form.

Is S-23 banned in sport? Yes. S-23 is prohibited at all times under section S1.2 of the WADA prohibited list. Anti doping laboratories have published detection methods for it and it has featured in adverse analytical findings.

How is S-23 different from other SARMs? Two things set it apart. It was developed as a male contraceptive candidate, so the published work deliberately characterised suppression of the hormonal axis rather than treating it as an unwanted effect. And its binding affinity for the androgen receptor reported in the rat work is higher than that of ostarine or andarine. What it lacks, compared with ostarine, is any human data at all.
