SARMs Bundles for Muscle Building, Bulking, and Cutting
Building a SARMs stack from scratch means researching which compounds are commonly combined, in what ratios, and for what goal. Our bundles do that work for you: each one groups 3-4 compounds already studied together for a specific outcome, at a lower combined price than buying each separately.
CORE SARMS delivers SARMs bundles to UK customers. We currently offer three bundles, each built around compounds frequently stacked together for that goal. Want to understand the stacking logic? The CORE Handbook has a full guide to bundles, usage and stacks.
What Is in Each Bundle?
Muscle Building Bundle
Combines Ligandrol (LGD 4033), RAD 140 (Testolone), Ostarine (MK 2866) and MK 677 (Ibutamoren) in one pack. Built for researchers focused on lean mass and strength. See the full muscle building range.
Bulking Bundle
Combines YK11 (Myostatin), Ligandrol (LGD 4033), RAD 140 (Testolone) and MK 677 (Ibutamoren) for mass and strength protocols. Read our guide to the best SARMs for bulking.
Cutting Bundle
Combines RAD 140 (Testolone), Ostarine (MK 2866) and Cardarine (GW501516) for fat loss with muscle retention. Read The Ultimate Cutting Stack: SARMs for Fat Loss.
Verified Quality Across Every Bundle
Every compound in every bundle is third-party lab-tested for purity and screened for contamination. Batch-specific certificates of analysis are available on our Lab Tests page, updated as new batches are tested.
Why Quality Matters
Contaminated or under-purity SARMs can introduce side effects unrelated to the compound itself, or reduce its research value. That’s why every product in these bundles is verified above 99% purity before it ships.

Frequently Asked Questions
Contact supportSARMs bundles are pre-selected stacks of compounds, including SARMs, combined to support specific fitness goals such as muscle building, bulking or cutting.
Each bundle contains 3-4 compounds commonly studied together for that goal. The exact compounds are listed on each bundle’s product page.
No, our SARMs bundles do not include PCT products. However, we have a dedicated post-cycle therapy supplement available for purchase separately.
SARMs bundles are designed to simplify product selection by combining compounds that are commonly stacked together. However, they may include more potent SARMs; hence, it is recommended to research the compounds pre-purchase.
Choose by research goal: the Muscle Building Bundle for lean mass and strength, the Bulking Bundle for mass-focused protocols, and the Cutting Bundle for fat loss with muscle retention. Each bundle’s product page lists its compounds and usage details.
