Ostarine Stack, Cutting, Bulking & Strength MK 2866 Stacks

In this post, we’ll go over Ostarine (MK 2866) stacks. We’ll go over practical examples of Ostarine stacks for 4 different goals:

  • Cutting
  • Bulking
  • Body Recomposition
  • Strength
Ostarine Stack

What To Avoid

Before constructing a stack we need to go over a few things to keep in mind.

Firstly, we should never plan a SARMs stack that exceeds 8 weeks. Going over 8 weeks will exponentially increase Testosterone Suppression with any SARM, let alone a SARMs stack.

Secondly, we shouldn’t stack Ostarine with some of the most suppressive SARMs like YK11 or S23.

Stacking Ostarine with SARMs like that will just be a complete waste of MK 2866 since it won’t even get to do anything. YK11, for example, is so much stronger than Ostarine that taking both compounds together will be practically the same as taking only YK11 except that you risk more side effects.

The last thing that you need to keep in mind are PCT (Post Cycle Therapy) products. It’s always a good idea to have those on hand. Check out my protocol and the products that I always keep on hand here.

Ostarine Stack For Cutting

The best Ostarine stack for cutting is Ostarine + Cardarine.

Ostarine will ensure that you hold on to all of your muscle mass during a deficit and even build some muscle of the calorie cut isn’t too drastic. Cardarine will help you with your endurance and make cardio a lot easier. This will help you out a lot with burning more calories which ultimately means more fat loss.

A great cycle using this stack would be 8 weeks of 10mg Ostarine and 10mg Cardarine. This is one of the best cycles for somebody that’s new to SARMs and has a goal of losing fat.

Cardarine isn’t a SARM and won’t cause any suppression of your natural Testosterone. That combined with Ostarine being the mildest SARM and causing the least suppression means that you’re likely to not even need to do a PCT protocol. 

However, I always recommend to get your bloodwork done before, during and after the cycle to keep track of your hormones and to know for sure if you need to do a PCT or not.

Ostarine Stack For Bulking

MK 677 stacked with Ostarine is one of the best beginner cycles for bulking and gaining lean muscle.

Ostarine will enhance your muscle-building potential and thus help you gain more muscle in a shorter period of time. MK 677 will help with your appetite to make sure you’re not in a calorie deficit and increase your natural growth hormone production which will help with muscle building, fat loss and increase your hair, skin and sleep quality.

An example cycle would look like this:

Week 1-8: Ostarine at 15mg per day.

Week 1-16 MK 677 at 15 mg per day.

We take MK 677 for 12-16 weeks because it’s a compound that needs to be taken for a longer period of time to get the full benefits out of it.

MK 677 isn’t a SARM (It’s a growth hormone secretagogue) and won’t suppress your production of natural Testosterone

On top of that, since we’re taking MK 677 for 4 to 8 additional weeks after we’re done with Ostarine, it will act as some sort of a PCT and help us recover the suppression from Ostarine without the use of other drugs. Read more about this in our MK 677 PCT guide.

Ostarine Stack For Body Recomposition

Most people that are planning on doing SARMs want to do a body recomposition (losing fat and gaining muscle at the same time).

A great Ostarine body recomposition stack is Ostarine coupled with RAD 140.

A good example cycle would look like this:

Week 1-8 Ostarine at 10 mg per day & RAD 140 at 10 mg per day

RAD 140 will be able to give us the muscle building potential that’s needed for a body recomposition.

Ostarine stacked on top of that will enhance our recovery times and help us be in the gym 5 times a week which will be needed for a successful body recomposition.

It’s important to know that for a successful body recomposition you need to stay at calorie maintenence. This way you’ll be able to stay at the same weight throughout the whole cycle as all the muscle mass gained will be roughly the same as the fat lost.

RAD 140 is one of the more suppressive SARMs and that is why it’s important to keep track of your hormones and have PCT products on hand. 

Ostarine Stack For Strength

If you’re only looking to gain strength, Ostarine stacked with LGD 4033 is probably the best Ostarine stack for you.

A good example cycle for this stack would look like this:

Week 1-8 Ostarine at 10 mg per day & LGD 4033 at 5 mg per day

Ostarine will help with the recovery times allowing us to be in the gym 5 times a week.

LGD 4033 coupled with Ostarine will really help with strength progress allowing us to break PRs week after week.

In order to keep the strength gained during the cycle, intense training is required after the cycle is over.

Ligandrol is a lot more suppressive than Ostarine so I suggest you read our LGD 4033 PCT guide before you start with this stack.


As we’ve seen in this article, we can stack Ostarine with different compounds in order to achieve differen goals.

You should choose your Ostarine stack depending on the results that you want to get.
