This stack is built for bulking and for those looking to increase size and muscle definition - combining RAD-140 and MK-677 (Ibutamoren).
RAD-140 (Testolone) is studied for selectively activating androgen receptors to support lean mass, strength and muscle efficiency. MK-677 (Ibutamoren) is studied for stimulating growth hormone and IGF-1, supporting protein synthesis, hypertrophy and tissue repair.
RAD-140: 1-2 tablets (10mg each) daily with breakfast, cycle 8-16 weeks. MK-677: 1-2 tablets (20mg each) daily, cycle 8-12 weeks. Do not exceed 2 tablets per product daily, and include a PCT afterward (see our Recharge 2.0 PCT).
Free UK shipping on all orders over £100. Every order goes out in plain, unbranded packaging with no external branding. Orders under £100 ship via standard tracked delivery.
Every batch is independently tested by a third-party lab before it is released for sale. Research products sold by APH Science are strictly for research purposes only and are not intended for human consumption. Consult a healthcare professional before use.

Product FAQs
Contact us Contact usWhat is in Bulking Stack?
Bulking Stack is a multi-compound stack from APH Science. Open the description and benefit blocks on this page for the full compound list and strengths per bottle.
Do stacks need PCT?
Most multi-SARM stacks are researched as suppressive. Plan recovery support (such as Recharge 2.0) into the protocol unless the individual compounds are clearly non-hormonal.
How do I take a stack?
10mg each) daily with breakfast, cycle 8-16
Can I buy the stack with PCT included?
Where a Complete your cycle option appears on the buy box, you can add Recharge 2.0 in one step. You can also add PCT from the cart drawer later.
Why buy Bulking Stack as a stack?
Stacks group complementary research compounds so the protocol ingredients ship together. Check each bottle’s strength on this page so your study design matches what is in the box.
Are stack compounds all equally suppressive?
Not always. Read each component. Many APH stacks still assume recovery planning because at least one bottle is commonly researched as suppressive.
How should stack research be structured?
Treat each compound’s published literature separately, then combine only if your protocol allows it. Label maximums on each bottle still apply.
Documentation and testing
Batches are put through APH’s third-party testing process before release. Ask for lot paperwork where you need it for lab records.
Storage
Store each bottle sealed, cool, and dry. Do not combine capsules into unlabelled containers if you need clear chain-of-custody for research notes.
What makes Bulking Stack different in the APH catalogue?
Bulking Stack is listed with APH Science's standard QC culture: clear labelling, UK dispatch, and the same cart thresholds as the rest of the store. Always read the product description and label for the specific compound or formula details.
If you are comparing similar products, use the dose, format, and intended research or supplement category on this page as your primary guide - not third-party marketing claims.
Who typically buys Bulking Stack?
Buyers usually arrive looking for a specific training or research goal and want a labelled, consistently supplied product from a UK-facing brand. Bulking Stack should be chosen only when it matches that goal and the product category on this page.
If you are unsure, use the on-page quiz (where shown), read the FAQs, or contact support before ordering multi-bottle quantities.
How should I store Bulking Stack?
Store Bulking Stack sealed in a cool, dry place away from direct sunlight, moisture, and heat sources. Keep out of reach of children. Do not use if the seal is broken or the product looks compromised.
Follow any extra storage notes on the label (for example cold-chain guidance on certain research formats).
Is this suitable to stack with other APH products?
Many customers build multi-product carts (for example a primary compound plus recovery support). Whether Bulking Stack fits a stack depends on the product class and your goal - use the description, FAQ, and quiz on this page as a starting point.
This is catalogue guidance only, not medical advice. When in doubt, keep the stack simple and verify compatibility yourself.
What makes APH Science different for this product?
Bulking Stack is formulated under the same UK-owned QC culture as the rest of the APH Science range - clear labelling, third-party testing culture, and plain packaging. Buyers compare us against generic marketplace listings because batch consistency and support matter when stacking a full protocol.
Every order ships through the same fulfilment flow as our SARMs, stacks, and supplements catalogue, so cart thresholds for free UK shipping and gifts apply the same way.
What dose is on the Bulking Stack label?
Use the milligram dose printed on the bottle and this page.
Can I stack Bulking Stack with other APH products?
Stack only what matches this product class. Check the description on this page rather than generic recovery or strength copy from another SKU.
This is catalogue guidance only, not medical advice.
What shipping and cart benefits apply when I buy Bulking Stack?
Bulking Stack counts toward free UK shipping over £100, free protein gift thresholds, and next-day gift tiers in the same cart as every other APH Science product. Discrete packaging is standard. Tracked options are available at checkout depending on destination and service level.
How should I store Bulking Stack after delivery?
Store Bulking Stack in a cool, dry place away from direct sunlight and moisture. Keep the bottle closed between uses. Do not use past any stated best-before guidance on the pack. If the product is a research peptide vial rather than a capsule bottle, follow the dry-storage and reconstitution notes on that product page instead.
Is Bulking Stack suitable for beginners?
If you are new to this category, start by reading the full product description, FAQ, and any dosage or research framing on the page. Bulking Stack is positioned for buyers who already understand the compound class - not as a casual everyday multivitamin. When in doubt, choose a lower entry point or speak to a qualified professional before use.
Does Bulking Stack qualify for subscribe and save or bulk pricing?
Where multi-bottle or bulk tiers are shown on the product page, the unit price drops as you increase quantity - that is the live price you add to cart. Subscription options appear only when configured for that SKU. Always check the buy box on Bulking Stack for the current offer rather than assuming a sitewide discount code applies.
What should I do if I have a question about my Bulking Stack order?
Contact APH Science support with your order number and the product name (Bulking Stack). Typical queries include delivery timing, batch documentation, and stacking advice. Response times are usually within one business day on UK working days.
Where do you ship from?
Orders dispatch from the UK with tracked shipping options. Free UK shipping applies on carts over £100.
How long does delivery take?
Timing depends on the service selected at checkout and courier performance. You will receive tracking when the order leaves the warehouse.
How are orders packed?
Orders are dispatched from the UK with standard e-commerce packing. Tracking is provided so you can follow the parcel in transit.
Is every batch third-party tested?
APH Science targets independent lab verification for research batches before release. Certificate or purity paperwork can be requested where available for your lot.
Is this for human consumption?
No. Research compounds, SARMs, and research peptides are sold strictly for laboratory research purposes only. They are not intended for human consumption, medical use, or as food or dietary supplements.
How do bulk buy discounts work?
Where Buy 1 / Buy 2 / Buy 3 tiers appear on the product, choosing a higher tier applies the stated saving at add-to-cart. The price on the button updates to match the selected tier.
How do I track an order?
Use the Track order page with your order details once you have confirmation and tracking. Contact us if a label has not appeared within the expected dispatch window.
How fast do UK orders ship?
Orders typically leave the UK warehouse within 1–2 working days. Free UK shipping applies over £100. International options depend on destination and product type - checkout shows available rates.
All orders use discreet outer packaging. Tracking is provided once the parcel is with the carrier.
Can I get batch / CoA documentation?
Where certificates of analysis or batch documentation are available for a product, APH Science can supply them on request. Include your order number and product name when contacting support.
Keep screenshots of the product page and your invoice for your own records if your lab requires them.
