The Intermediate Cutting Stack combines three compounds supplied as three separate bottles of 90 capsules each: andarine (S-4) at 25mg per capsule, ostarine (MK-2866) at 10mg per capsule and cardarine (GW-501516) at 10mg per capsule. Two are selective androgen receptor modulators and one is a PPAR delta agonist. All three are manufactured in the United Kingdom. Supplied for laboratory research only and not for human consumption.
Each compound in this bundle has its own literature, and the honest way to describe a multi compound bundle is to summarise each one separately.
Andarine (S-4), 25mg per capsule, is preclinical. Gao and colleagues showed in Endocrinology in 2005 that it restored levator ani muscle and bone strength in castrated rats with only partial prostate stimulation, and Kearbey and colleagues reported preserved bone mineral density in ovariectomised rats in 2007.
Ostarine (MK-2866), 10mg per capsule, is the most studied compound in the category. Dalton and colleagues reported in the Journal of Cachexia, Sarcopenia and Muscle in 2011 that twelve weeks of enobosarm increased total lean body mass and stair climbing power against placebo, and Dobs and colleagues reported similar lean mass findings in Lancet Oncology in 2013.
Cardarine (GW-501516), 10mg per capsule, is a PPAR delta agonist rather than a SARM. Oliver and colleagues reported raised HDL in obese monkeys in PNAS in 2001 and Narkar and colleagues reported increased running endurance in mice in Cell in 2008. Development stopped after long term rodent studies reported tumours across multiple organs.
No published trial has tested these compounds together. Every figure above comes from a study of a single compound in a specific population, and combination pharmacology cannot be inferred by adding those studies together. Where components suppress the endogenous hormonal axis, as LGD-4033 and RAD-140 do, no published data describe what happens when they are combined. This bundle exists because researchers buy these compounds together, not because a combination protocol has been validated.
Dexterz Labs products are manufactured in the UK to a fixed strength per capsule with the batch number printed on every bottle. Every batch is independently tested and its certificate of analysis is published on the product page and on the Lab Testing page. 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 this bundle legal in the UK in 2026? None of the compounds in this bundle is controlled under the Misuse of Drugs Act 1971, so buying and holding them as research chemicals is lawful in the United Kingdom in 2026. Selling or advertising any of them for human use would make them unlicensed medicines under MHRA rules, which is why this listing carries no usage guidance.
How fast is delivery? UK orders go out the same working day when placed before the cut off and arrive by tracked delivery, usually within two to three working days for UK addresses, with a next day upgrade available at checkout. Parcels are plain and unbranded, with nothing on the outside that identifies the contents. International delivery is available to most destinations, with a restricted list at checkout covering countries where customs rules make delivery unreliable.
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.
Are these compounds banned in sport? Yes, all of them, at all times. The SARMs fall under section S1.2 of the WADA prohibited list, MK-677 under section S2 as a growth hormone secretagogue, and cardarine and SR-9009 under section S4.5 as metabolic modulators. Detection methods exist for each.
What is the difference between this bundle and the beginner version? This one adds cardarine, which is not a SARM and does not act on the androgen receptor at all. It is a PPAR delta agonist studied in endurance and lipid contexts. Adding it changes the character of the bundle from two androgen receptor ligands to a mixed pharmacology set, and it brings the rodent carcinogenicity finding described above into the picture, which is a point buyers should weigh rather than ignore.
