Jacked AF is a 60-capsule triple blend: 10mg Andarine S4, 10mg MK-677 and 10mg Ostarine in every capsule. Andarine and Ostarine are SARMs that act at the androgen receptor. MK-677 is a ghrelin receptor agonist and GH secretagogue - not a SARM.
Two receptor systems in one formula. Post-cycle therapy needs to be planned before the window starts.
Jacked AF puts two SARMs and one GH secretagogue in the same capsule. It is for a defined research or training window, not a daily multivitamin. Read the dose, PCT notes and stacking context on this page before you add more than one bottle.
Andarine S4 is studied for supporting muscle definition and strength. MK-677 is studied for supporting growth hormone levels and recovery. Ostarine is studied for supporting lean muscle mass, endurance and fat loss.
One pill daily, ideally with food to support absorption. Follow the product label instructions and pair with a healthy diet and consistent training for optimal results.
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.

Key benefits
Andarine S4 at the androgen receptor
10mg. S4 is a SARM developed around selective androgen-receptor activity in muscle and bone.
How it works
MK-677 on a second pathway
10mg. Acts at GHSR, the ghrelin receptor. Researched for GH release, IGF-1, appetite and sleep. Not a SARM.
How it works
Ostarine for the lean-mass profile
10mg. Clinically researched for changes in lean body mass and physical function.
How it works
Why use Jacked AF?
Jacked AF is built around two jobs at once. Andarine S4 and Ostarine are SARMs that bind the androgen receptor. MK-677 works somewhere else entirely - GHSR, the ghrelin receptor linked to growth hormone release, IGF-1, appetite and sleep.
That is why all three are here. Two SARMs for one receptor pathway. One GH secretagogue for another. Every capsule contains 10mg of each compound.
-
Two SARMs target the androgen receptorAndarine S4 and Ostarine both act at androgen receptors in muscle and bone.
-
MK-677 targets a different receptorIt acts at GHSR, not the androgen receptor. It is a GH secretagogue, not a SARM.
-
One complete triple formula10mg of each compound per capsule. 60 capsules in the bottle.
Three compounds. Two pathways.
Andarine S4 and Ostarine belong to the same compound class, but they are not copies of each other. S4 was developed as a selective androgen receptor modulator with a tissue-selective profile. Ostarine has clinical data on lean body mass and physical function.
MK-677 is the third piece. It is a ghrelin receptor agonist, not a SARM. That adds a second receptor system instead of stacking a third androgen-receptor compound.

Ostarine for the lean mass profile10mg. Clinically researched for changes in lean body mass and physical function.

MK-677 for the GH secretagogue side10mg. Researched for GH release, IGF-1, appetite and sleep.
Needs a PCT
Jacked AF contains two SARMs. Post-cycle recovery needs to be planned before the window begins. Androgen-receptor modulation can affect natural testosterone and related hormone markers.
MK-677 does not cancel that out. It works through a different receptor and is not PCT. Recharge belongs after the window, followed by bloodwork to check recovery.

Product FAQs
Contact us Contact usWhat is in Jacked Af?
Jacked Af 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.
What is the typical dose for this stack?
10mg Andarine S4, 10mg MK-677, and 10mg Osta
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 Jacked Af 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 Jacked Af different in the APH catalogue?
Jacked Af 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 Jacked Af?
Buyers usually arrive looking for a specific training or research goal and want a labelled, consistently supplied product from a UK-facing brand. Jacked Af 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 Jacked Af?
Store Jacked Af 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 Jacked Af 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?
Jacked Af 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 Jacked Af label?
Use the milligram dose printed on the bottle and this page.
Can I stack Jacked Af 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 Jacked Af?
Jacked Af 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 Jacked Af after delivery?
Store Jacked Af 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 Jacked Af 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. Jacked Af 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 Jacked Af 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 Jacked Af for the current offer rather than assuming a sitewide discount code applies.
What should I do if I have a question about my Jacked Af order?
Contact APH Science support with your order number and the product name (Jacked Af). 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.
