If you need the batch report for research records, contact sales@sarmsstore.co.uk with your batch number.

Orders placed before 2pm Monday to Friday are dispatched the same day. Tracked UK delivery is free over £60 (£3.49 below), usually two to three working days, with a next day upgrade for £4.49 at checkout. Packaging is plain with no product names on the outside.

Unopened products can be returned within 30 days of delivery for a full refund, and faulty items within 14 days.

Is MK-677 legal in the UK in 2026? MK-677 is not a controlled substance under the Misuse of Drugs Act 1971 and is not scheduled as an anabolic steroid, so it is lawful to buy and hold as a research chemical in the United Kingdom. The MHRA treats it as an unlicensed medicine if it is sold or advertised for human use, which is why it is listed here strictly for laboratory research.

How fast is delivery? Orders placed before the daily cut off are despatched the same working day by tracked delivery, with UK orders usually arriving within two to three working days and a next day upgrade available at checkout. Everything leaves in plain outer packaging with no reference to the contents or to the compound on the outside of the parcel. International delivery is available to most countries, although some destinations are restricted because of local customs rules, and restricted countries are listed at checkout.

How should the capsules be stored? Store sealed, below 25C, in a dry place away from sunlight and heat. Under those conditions the material is stable to the expiry date shown on the bottle. Humidity is the usual problem with capsules, so a cupboard is better than a windowsill or a bathroom shelf.

Is MK-677 banned in sport? Yes. Growth hormone secretagogues are prohibited at all times under section S2 of the WADA prohibited list, and ibutamoren has been detectable in anti doping testing since 2015. Its long half life means the detection window is not short.

How is MK-677 different from a SARM? It works on a different receptor entirely. SARMs such as ostarine and LGD-4033 bind the androgen receptor. MK-677 binds the ghrelin receptor and raises the body's own pulsatile release of growth hormone, with IGF-1 rising downstream. That is why the published trials do not describe androgenic suppression, and why the reported issues centre on appetite, fluid retention and glucose handling instead.
