Ostarine MK 2866 was the very first cycle I ever ran. I knew it was one of the most well-researched SARMs and was proven to shred body fat and pack on lean muscle mass.
So, I gave it a shot. I decided to take the “advanced level” Ostarine MK 2866 dosage of 25mg/day which is pretty high, and what many bodybuilders recommended at the time.
I recorded everything on my phone, like:
- How Much Muscle Mass I Gained
- How Much Body Fat I Lost
- How Much Strength I Gained
- What My Cycle Felt Like
- My Caloric Intake
- Any Noted Side Effects
- …and more
So, if you are thinking of taking Ostarine MK 2866 to experience the muscle growth and fat loss for yourself, consider reading this log from start to finish, so you know what to expect.
Ostarine MK-2866 Cycle Overview
The goal of my first cycle was simple. I wanted to increase muscle mass and lose body fat, so basically I wanted to do a recomposition. I also just wanted to feel what Ostarine felt like.
Here were my cycle details:
- Cycle Length: 12 Weeks
- Ostarine Dosage: 25mg/day
- Goal of Cycle: Recomposition
- Workout Routine: 5-Day Split
- On Cycle Support: Yes
- Post Cycle Therapy: Yes
- Muscle Gained: 15 Pounds
- Body Fat Lost: 7 Pounds
I could have opted to do a shorter cycle duration like 4 weeks or 8 weeks, but it was my first Ostarine cycle, so I wanted to see what kind of results I could get if I did a full cycle.
…and needless to say, the results did not disappoint.
Stats Before & After
I'll give a day-by-day and week-by-week breakdown of what I experienced in a second, but overall I experienced way more physical energy, better cardio sessions, less muscle aches, faster recovery, and as I expected, lean body mass just packed on like it was nothing.
Here were my stats before the cycle:
- Weight: 163lbs
- Bodyfat: ~13.5%
- Bench Press: 225lbs
- Deadlift: 315lbs
- Squat: 235lbs
- Overhead Press: 125lbs
I was in decent shape, but was bulking at the time so had a decent amount of muscle mass on my body, but still needed to lose weight for my abs to really show. They were barely visible.
Here were my stats AFTER the cycle:
- Weight: 171lbs
- Bodyfat: ~8%
- Bench Press: 285lbs
- Deadlift: 395lbs
- Squat: 305lbs
- Overhead Press: 185lbs
As you can see, many of my lifts I was able to add almost 100lbs on. Even experienced bodybuilders can't do this in a YEAR when they aren't on cycle. That's how strong it is.
MK-2866 Cycle Log
As I said, when I started this cycle, I was totally new to SARMs (selective androgen receptor modulators) so didn't know what I was doing that much. I was still able to get great muscle gains and burn fat at the same time, however.
I noticed my athletic performance increased almost immediately. In the first week I had more energy, more strength, and it may be placebo, but I even noticed increased muscle size.
My First Day Taking Ostarine
The first day of my cycle! I was so excited. I woke up and immediately took 25mg of Ostarine MK 2866 first thing in the morning. I just put it straight under my tongue then got to the gym.
I was so excited to have my first workout on Ostarine MK 2866… and thanks to the short half life of Ostarine and other selective androgen receptor modulators, it acted FAST.

My very first workout and I could already feel a difference. I felt way more energy, endurance, increased aggression, and focus in the gym. My workout was amazing.
Research suggests that MK 2866 kicks in fast, due to its short half life, so while some people may think this is placebo, it actually isn't. Ostarine gets into and out of your system within just 24-36 hours, which means it STARTS and STOPS working very quickly.
Weeks 1-2
The first couple of weeks were great. I noticed increased muscle mass as if I was taking anabolic steroids or something. I also noticed fat loss, just from looking in the mirror.
I experienced all the benefits as I did the very first day:
- More Energy
- More Focus
- More Endurance
- Better Pumps
Overall, I knew that MK 2866 was a winner, and a SARM I'd likely take again.
Weeks 3-4
Here, I was REALLY starting to see some good muscle gain. My lifts were going way up in the gym, and all my friends started to notice my increased muscle mass and muscle growth rate.
By weeks 3-4, Ostarine MK 2866 had bound to all of my androgen receptors, meaning that the MK 2866 was in full effect. It felt amazing. All I had to do was sneeze and I'd pack on lean muscle mass, then sneeze again and I'd get some fat loss.
Weeks 5-6
By now I was fully into the swing of things. I could see the extra muscle mass, and I knew that this selective androgen receptor modulator was working, because of how fast my muscle tissue was recovering, and how I wasn't even sore after the most intense workouts.
Unlike steroids, I noticed almost no side effects. No loss in libido, no acne, no hair loss, and no oily skin. Just pure muscle growth, packing more lean muscle mass on each and every day.
Weeks 7-8
By now, I had a very clear and visible six pack. There was almost zero water retention, which made me look absolutely shredded. Even professional bodybuilders were giving me glances in the gym (they probably noticed my rapid muscle gains and knew I was on cycle).
My ability to maintain muscle mass was insane. Even on the days I would not follow my diet plan and skip out on eating enough calories, I noticed absolutely zero muscle wasting.
So, I decided to do a mini cutting cycle for the last month I had.
Weeks 9-10
By now, I'd decided to start a mini cutting cycle. It wasn't going to be anything crazy, just cutting back maybe 200-300 calories per day and seeing how it affected my muscle growth.
Much to my surprise, I experienced literally zero muscle atrophy. In fact, not only did I have no muscle loss or muscle wasting, but I actually GAINED muscle, even in a caloric deficit.
This is why even low dose MK 2866 is one of my favorite SARMs to build muscle on cutting cycles. Ostarine is such a powerful SARM that it literally will turn your body fat into muscle, which makes it a dream if you're trying to cut but not lose muscle mass.
Weeks 11-12
The last two weeks of my cycle were awesome, aside from the fact that I knew I'd be getting off the Ostarine MK 2866 pretty soon. I was a little bit worried about weight loss after my cycle, due to the decreased testosterone production I knew would temporarily happen.
Despite my worries, MK 2866 gave me the same effects the last month as it did the first month – insane strength, awesome endurance, a huge energy boost, and of course, shredding off pounds of fat and packing on slabs of muscle.
Post Cycle
That was it! My Ostarine cycle was complete. Not going to lie, I was pretty worried about muscle loss afterwards, because I'd heard you lose a lot of the gains you make on cycle.
Thankfully, I ended up keeping almost all of my gains due to a good Ostarine PCT. I think I lost around one or two pounds, but my lifts didn't go down at all. This was a HUGE relief.
Conclusion
In conclusion, Ostarine MK 2866 isn't as powerful as anabolic steroids, but according to clinical trials, is still an extremely powerful anabolic agent that will grow muscle tissue.
My first Ostarine cycle was a huge success. I experienced minimal testosterone suppression, no joint pain, no liver damage, and a metric ton of anabolic activity (muscle growth).
My Ostarine dosage was a little bit high for a first timer. Usually I recommend you only take around 10mg/day of Ostarine for your first cycle, but back then nobody knew any better.
