Mass Series 60 Capsules

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 product legal in the UK in 2026? The compounds used across our mass range are not controlled substances under the Misuse of Drugs Act 1971, so buying and holding this material as a research chemical is lawful in the United Kingdom in 2026. Selling or advertising it for human consumption would make it an unlicensed medicine under MHRA rules, so this listing is written for laboratory research only.

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? 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. SARMs are prohibited at all times under section S1.2 of the WADA prohibited list and growth hormone secretagogues under section S2. Detection methods are established for each and the detection windows are not short.

How does this differ from the multi bottle bundles? Format, not pharmacology. The bundles supply each compound in its own labelled bottle with its own certificate, which suits work where the compounds need to be handled separately. The Mass Series consolidates them into one capsule. Neither format has been validated as a combination by any published trial.
