What is AC-262?

AC 262 is a non-steroidal tissue-selective potent androgen receptor modulator with partial agonist activity relative to the natural androgen testosterone (1). It is gaining more popularity among bodybuilders and fitness enthusiasts.

Selective Androgen Receptor Modulators (SARMs) are a class of androgen receptor ligands that bind to androgen receptors and display tissue-selective activation of androgenic signaling (2).

SARMs have selective anabolic effects on muscle and bone and were originally synthesized for the treatment of muscle wasting, osteoporosis, and breast cancer (3), in addition to increasing exercise endurance.

Originally, AC 262 was developed by Acadia Industries initially as a potential treatment for prostate cancer and Alzheimer’s.

AC 262 differs from other SARMs in its ability to leave testosterone levels unsuppressed as it acts as a partial agonist (1).

How Does AC 262 Work?

Unlike other androgens/testosterone or anabolic steroids that target all body tissues, AC-262 is extremely selective for AR, having no significant affinity for the other 47 human nuclear receptors including the steroid receptors estrogen ERs, glucocorticoid GR, mineraloid MR, and progesterone PR (1).

This particular binding leads to molecular changes in our body, triggering an increase in muscle mass and bone strengthening (1).

Previous animal studies showed that AC 262 produces a maximal effect of around 66% of the anabolic action of testosterone, but only around 27% of its potency as an androgen (4,5).

Does AC 262 Increase Testosterone Levels?

AC 262 is a selective androgen receptor modulator (SARM). It is often studied for its potential effects on muscle growth and performance.

However, whether AC 262 increases testosterone levels is a topic of debate. Some research indicates that AC 262 does not significantly boost natural testosterone production. Instead, it binds to androgen receptors, mimicking some of testosterone’s effects without actually increasing testosterone levels.

This means that while AC 262 may help with muscle building and strength, it might not elevate testosterone in the body. As a result, users may experience benefits similar to those of higher testosterone without the associated hormonal changes.

It’s important to note that long-term effects and safety of AC 262 are still under research. Consulting with a healthcare professional is recommended before considering its use.

Benefits of AC-262 

What attracts the audience towards any product or supplement are the benefits it curtails, especially the potential associated health effects.

AC 262, a non-steroidal SARM, has growth- and bone-promoting effects, along with fewer associated negative side effects compared with anabolic-androgenic steroids (4). It can also enhance muscle mass, definition, and strength.

Interestingly, A 2-week chronic study in castrated male rats indicated that AC 262 significantly improves anabolic parameters in these animals, especially in suppressing elevated LH levels (1).

Additional benefits include:

Enhanced Muscle Growth:

AC 262 promotes the growth of lean muscle mass, aiding in achieving a more defined physique.

Improved Bone Density:

Alongside muscle growth, AC 262 contributes to strengthening bone density, reducing the risk of fractures and injuries.

Reduced Risk of Negative Side Effects:

Compared to traditional anabolic-androgenic steroids, AC 262 is associated with fewer adverse effects, making it a safer alternative for muscle enhancement.

Potential Hormonal Regulation:

Studies suggest that AC 262 may help regulate hormone levels, such as suppressing elevated LH levels, which can contribute to overall hormonal balance.

Enhanced Exercise Performance:

Users of AC 262 report improvements in exercise endurance and performance, allowing for more intense and prolonged workouts.

AC 262 Usage in Bodybuilding

AC 262 triggers muscle growth and bone strength. Therefore, it is becoming popular among bodybuilders.

To date, there are no scientific studies about the use of AC 262 in humans. Users recommend AC 262 is 10-20 mg for 30 days.

However, this is not scientifically proven to be safe or efficient. Thus, before purchasing AC-262 for personal use, it is a must to consult with your physician/healthcare provider first.

The legal issues concerned with AC 262 or any other SARM can push away many customers since the U.S. Food and Drug Administration (FDA) is warning consumers that the agency continues to receive adverse event reports related to SARMs among teens and young adults.

SARMs including AC 262 are not FDA-approved.

However, if you’re looking to buy AC 262 for research purposes, you can easily do so. But for personal use, you will have to do so under a healthcare provider’s guidance.

Who Should Use AC 262?

AC 262 is widely used among people in the fitness and bodybuilding industries. Thus, if you’re looking for a compound that could help kickstart your journey in building healthy muscle mass and endurance, AC 262 is just for you!

The drug is also a novel therapy for patients with Prostate cancer. However, AC 262 has NOT been clinically approved and little is known about its beneficial effects and other adverse effects on users (3). Therefore, extensive research is required.

Forms of AC 262

AC 262 is mostly purchased in the form of capsules due to its feasibility. However, in certain stores, you might also find it in the form of powder.

AC 262 Dosage

AspectAC 262 Dosage
Recommended Dosage10-20 mg for 30 days πŸ“…
DependenceπŸ’ͺ Purpose, gender, weight, medical history

The dosage for a particular SARM is highly dependent on the purpose of using it, gender, weight, and previous medical history. Users recommend AC-262 is 10-20 mg for 30 days.

However, this is not scientifically proven to be safe or efficient.

AC 262 Cycle

Doing the AC 262 cycle for approximately 30 days is suggested to see fruitful results. 

Even so, AC 262 doesn’t suppress Testosterone levels significantly by using PCT. However, a full Post Cycle Therapy should be done to be on the safe side. 

Best Time To Take AC 262

Like every other SARM, AC 262 is recommended by users to be taken in the morning, preferably before your workout. This way, the drug will have enough time to kick in your body.

AC-262 Side Effects

AC 262 is less potent than other SARMs and therefore, it may be associated with fewer or less intense side effects.

However, there are almost always certain side effects associated with SARMs. Primarily, these side effects result from not being able to abide by the given doses and cycle.

Studies and reports show SARMs are associated with serious or life-threatening health problems (6), such as:

  • Increased risk of heart attack or stroke
  • Psychosis/hallucinations    
  • Sleep disturbances
  • Sexual dysfunction 
  • Liver injury and acute liver failure 
  • Infertility
  • Pregnancy miscarriage
  • Testicular shrinkage

AC 262 Reviews

Because AC 262 is not such a highly used SARM at the moment, you wouldn’t find many of the customer reviews available. 

Nonetheless, I tried to find some comprehensive customer experiences. 

One such user enthusiastically talks about his AC 262 experience:

β€œHappy Saturday brothers. I don’t post a lot on here, but I am about 4 weeks into a run on AC 262. I will say this, it’s a great product. I’m leaner and my strength has gone up. I’m an off and user of PEDs for the last 15 years, usually 1-2 12-week cycles a year. I’ve recently transitioned to SARMs and my TRT dose. There are a couple of YouTube videos on it and it’s spot on. It’s like Ostarine meets Equipoise. I was a tad leaner on Ostarine but much stronger with AC 262.

Yes, I get blood religiously and they look good as of last week. I’ll get some more done in the next 6-8 weeks. The only side effect is my aggression is up just a bit. Other than that, good to go.”

However, AC 262 might just not be for everyone as stated by him: 

β€œI just took my first dosage from this supplier and to be honest I feel pretty lethargic after a 10mg dose, Idk why. Like I’m tired of doing the basic stuff, might have to return this bottle. I am not liking how I am feeling about this, I thought this shit was supposed to give you energy.”

AC 262 Stack

You might have heard people stacking their SARMs. With the synergistic effects of multiple SARMs within the given recommended dosages, different systems of your body can work simultaneously. 

However, this can be risky because as much as you may be increasing the beneficial effects, you are also increasing the risk for side effects.

AC 262 and Andarine

AC 262 and Andarine/S-4, both SARMs, work on increasing muscle mass, and bone strength. With the collective effort of both drugs, the time needed to shape into an ideal body is shortened significantly.

AC 262 vs. Ostarine 

You probably would have heard more about Ostarine as compared to AC 262. People use ostarine for athletic performance, involuntary weight loss due to illness, breast cancer, and many other conditions, but there is no good scientific evidence to support these uses (7).

Ostarine can also be used by women who are into bodybuilding. Compared to AC 262, Ostarine is an investigational drug and therefore not approved for any use by the US FDA.

Ostarine might cause liver damage and other serious side effects such as heart attack (7).

AC 262 vs. ACP-105 

The Acadia industries manufacture these SARMs. Thus, the working mechanism and the anabolic: androgenic ratios are more or less comparable. With ACP-105 having a greater anabolic activity, it is preferable to use AC 262.

Besides this, ACP-105 has increased research-based evidence to support the benefits the drug curtails.

Is AC 262 Legit?

AC 262 is gaining much more attention than previously anticipated in the fitness industry. Its profound effects on building muscle mass and strength can greatly add to the current SARM stacks

One might be a bit confused since, in contrast to anabolic steroids and other SARMs, the potency of AC 262 is weak. Nonetheless, this also means you may experience fewer side effects.

Conclusively, AC 262 is one of the newest and most effective SARMs, with possibly fewer side effects. However, the FDA hasn’t yet approved the drug, therefore, before getting AC 262 for personal use, consult with your healthcare provider first.

What is AC-262 used for? 

AC-262, being a SARM, is used to increase muscle mass, strength, bone density, endurance, and lose of excess subcutaneous fat. Animal research also indicates a lowering of plasma Luteinizing hormone levels. 

How long should you cycle with AC-262? 

It is advised for both men and women to cycle their AC-262 for approximately 30 days to see significant results. 

Should you do PCT after AC-262?

Post Cycle Therapy (PCT) is often recommended after cycling with SARMs. It is due to the decreased levels of testosterone found after the supplementation. Since AC-262 doesn’t cause marked suppression in testosterone levels, you may not need to undergo PCT after a cycle. However, to be on the safer side, it won’t harm to use it. 

Are there any side effects with AC-262? 

Unlike other SARMs and anabolic steroids, AC-262 is less potent and therefore, may be associated with fewer side effects.

Is AC-262 FDA approved? 

No, like every other SARM, AC-262 is not yet approved by the FDA. Thus, it would be best to do AC-262 supplementation with a healthcare provider’s guidance.

Will going over 30 days of AC262 hurt the body.

I did a 90 day cycle of AC262. Started at 10mg per day and upped it 10mg after two weeks then again another 10mg after two more weeks. So got up to 30mg everyday but eventually decided 20mg every day was the sweet spot for me. I micro dosed enclo the last 4 weeks at 3.25mg everyday also. My back squat went from 275lbs to 365lbs and deadlift went from 405 to 500. My body weight went from 175-185 up to 205 and even months after I was still holding 200lbs body weight. I did pre and post blood work. Mildly affected my lipids and liver enzymes. I would recommend doing the micro dose of Enclo when using a higher dose of AC because of how it can thrash your FSH and LH levels. Also I conceived a child while on this cycle and she is no here and beautiful and healthy. I made posts of my progress on Reddit on a couple Sarms pages.
