What is Andarine?
Andarine (S4) was developed by GTX Inc. for the treatment of muscle wasting, osteoporosis, and BPH (enlargement of the prostate). It belongs to the class of drugs called SARM’s – selective androgen receptor modulators. Today, it is popularly used and sold as a research chemical, which is used by athletes who seek to get all of the strength benefits and lean muscle gains without the harmful side effects observed with anabolic steroids. Moreover, andarine is also used as part of steroid stacks to improve a cycle without adding more side effects, or aromatization.
Medical Studies
There have been ample studies done on andarine. For instance, one study showed that taking a small dosage of S4 every day restored skeletal muscle. Furthermore, in comparative studies with dihydrotestosterone (DHT), increases in bone mass and strength were observed at a higher rate with andarine than with DHT. In addition, more studies showed that andarine was more effective at losing fat and creating lean muscle mass, and it did so in a shorter amount of time with significantly fewer side effects than anabolic steroids.
Athletic uses
Due to the fact that andarine binds to androgen receptors, it can increase strength and build lean muscle mass without creating water weight, drying out the joints, stressing the liver, or causing severe suppression. What’s more, there is strong evidence that S4 also helps prevent osteoporosis, meaning that it will strengthen bones and soft tissues within the body. Likewise, andarine is great at preventing muscle wasting for those who choose to use it as a bridge between steroid cycles in order to keep muscle mass gains.
How it Works
All SARM’s work by binding to the androgen receptors, which results in anabolic activity. Furthermore, there is more protein synthesized, allowing more muscle to be created. These effects are similar to those seen with anabolic steroids. However, in the case of SARMS, there is no aromatization, liver strain, severe HPTA (hypothalamic pituitary testicular axis) suppression, and general side effects.
Stacking
Andarine can be used by itself, but it works even better when stacked because different drugs and compounds will work in synergy. There are a few ways to stack andarine, which I will illustrate below. All milligram (mg) examples are daily dosages, and you can run andarine for up to 12 weeks at a time.
1. Endurance: you can stack andarine at a low dose with cardarine (GW 501516) at 20mg per day for an increase in endurance.
2. Fat loss: the best shredder stack would be the combination of 20mg of cardarine with 50-75mg of andarine. This combination is well known as a potent ‘cutting’ stack.
3. Anabolic steroid stack: Stacking andarine as part of an anabolic steroid cycle is a good way to help increase strength and lean muscle mass without giving additional side effects to your cycle.
4. As a stand-alone: Andarine is used by itself at 50-75mg. It is, in my opinion, one of the best SARM’s for increasing strength quickly. You will be moving more weight within 1-2 weeks, and the side effects will be minimal.
5. SARMs triple stack: If you want to recomp, andarine stacks beautifully with cardarine and ostarine (MK 2866).
6. Bridging: Andarine is great at preventing muscle wasting, so you can use it between cycles because it is very minimally suppressive.
Side Effects
Andarine does not aromatize, it is not suppressive when used properly, and it will not harm the liver.
However, andarine is known for one side effect – its affinity to bind to the androgen receptors in the eyes, which is not permanent or harmful. When this happens, the user may have problems adjusting their vision from darkness to light, or they will notice a yellow tint. If this becomes a problem, you can lower the dose or take a couple of days off from taking it. Therefore, there is nothing to worry about because once the compound is stopped, your vision will return to normal within a few days to a week.
Half-life
The half-life of andarine is only 4-6 hours, so split dosages are a good idea.
Dosage and use
The typical dosage is 50-75 mg total per day, taken in the morning and in the evening in split dosages. In liquid form, you are to carefully drop the liquid into the mouth and swallow (do not hold it under the tongue). And then chase it down with some juice or water. Besides, do not mix the liquid into a cup with juice. Because it can sink or stick to the cup and be lost.

So while the name Superdrol is still often used, that particular brand is no longer manufactured. Some supplement companies continue to sell prohormone formulas over the counter under the name Superdrol, but it’s important to know these are not the anabolic steroid Methasterone.
Those who are familiar with the steroid Masteron will find that Methasterone is quite similar. Masteron is a non-17a-alkylated form of Methasterone, making these two steroids closely related.
Guys who are more prone to the effects of aromatizing steroids which bring about estrogenic effects like gyno and water retention can greatly benefit from Superdrol, as it does not aromatize and therefore provides an option to those users who can struggle with the estrogen-related side effects of some other steroids.
Superdrol Cycle
Bodybuilders typically take anywhere from 10-20mg of Superdrol a day, lasting from 4-6 weeks. Some advanced bodybuilders go as high as 30 or 40mg, but this is playing Russian roulette with your health.
Because of its devastating effects on the liver, a 4-week Superdrol cycle is sufficient for most bodybuilders.
Superdrol dosages should be spaced out throughout the day, as Superdrol is very fast-acting. Thus, to keep steady levels of serum testosterone users may take 10mg in the morning and 10mg in the evening.
Taking a full day’s dose in one sitting is likely to cause fewer gains and harsher side effects, as testosterone levels will become less stable (with peaks and troughs).
Important: Strictly no alcohol or supplements/medications that compromise the liver should be administered whilst taking Superdrol.
500mg/day of TUDCA should be taken to decrease liver damage, as well as 4g/day of fish oil to minimize large spikes in blood pressure.
Superdrol should not be stacked with other steroids, due to its high toxicity. Anadrol, Winstrol, Dianabol, and other hepatotoxic steroids should be avoided, due to their hepatotoxic effects.
Example of Rx Pharmaceuticals who have taken Superdrol.

This user cycled Superdrol for 4 weeks, taking 30mg/day for week 1, and 40mg/day for weeks 2-4.
He reported gaining 22lbs whilst bulking and eating in a calorie surplus.
His body fat percentage has only increased slightly.
These are impressive gains, considering a steroid user will struggle to grow much after his/her first few cycles. Superdrol is rarely ever taken by a beginner, yet still has the power to take muscular size and strength to new levels.

This user took Superdrol for a month and mentioned he was putting on it.
As you can see his back thickness has improved significantly, despite eating in a calorie deficit.
Eating maintenance or surplus calories is optimal for maximum muscle/strength gains on Superdrol; however, his results were impressive.
The user mentioned gaining 10lbs, which perhaps may be closer to 15lbs of lean muscle when accounting for a month’s worth of fat loss.
He also mentioned making the majority of his gains during the 3rd and 4th weeks of his cycle.
Superdrol and Anadrol are somewhat similar, with both of them being very powerful and toxic oral steroids. Superdrol mg per mg is a lot stronger, hence how only 10-20mg is needed for great results. In comparison, a typical Anadrol dose is 50-100mg.
The main difference between the two steroids is that Superdrol is not estrogenic, thus you won’t have any gyno or water retention concerns. Whereas on Anadrol, water retention is almost certain and gynecomastia is possible.
Both of these steroids should only be taken by advanced bodybuilders, due to their drastic effects on the liver and heart. They should never be taken together.
Superdrol and Dianabol are also fairly similar, with both being powerful muscle and strength builders. They are also both orals.
However, the main difference between Superdrol and Dianabol is estrogenic and androgenic side effects.
Dianabol aromatizes, and thus comes with water retention and potentially gynecomastia (whereas Superdrol doesn’t).
Dianabol is not particularly androgenic, whereas Superdrol is in practice.
Thus, Superdrol will likely result in more incidents of hair loss, acne, and prostate enlargement.
Beginners should strictly avoid Superdrol due to its high toxicity. It should be the last compound a novice should think of taking.
There’s also no reason why a beginner would want to take Superdrol, as a testosterone cycle is much safer; and very capable of producing exceptional muscle and strength gains.
Taking Superdrol as a first cycle would be the equivalent of diving straight into the deep end when learning how to swim.
However, a beginner may be able to take Superdrol and remain unscathed if they ran a very low dose; such as 5mg per day. Such low doses are not commonly taken among bodybuilders, thus it’s uncertain if beginners would experience positive results on 5mg/day of Superdrol; compared to 350mg/week of testosterone.
Superdrol can be an effective steroid when cutting. Its effects are androgenic in practice, thus when combined with a calorie deficit, users can expect enhanced fat loss.
Its ability to cause huge and full muscles (due to additional glycogen), is why some bodybuilders take it briefly before a contest.
However, a question users should ask is:
Is taking Superdrol for several weeks optimal when cutting?
The answer most likely is no.
Users’ results when cutting will largely be dictated by their diet and workouts. Powerful steroids may create a dryer appearance and speed up fat loss somewhat; however, the results are unlikely to be worth it for the strain Superdrol will place on the body.
A wiser compound to utilize when cutting would be Anavar, as its side effects are very mild compared to Superdrol. Also, Anavar is very capable of stripping fat and adding lean mass when in a calorie deficit.
Superdrol is one of the most powerful anabolic steroids available, thus its effects on muscle mass and strength are immense.
It is perhaps the best steroid for transforming a person’s physique quickly, with a short half-life (8-12 hours). Thus, results can be experienced in the early stages of a cycle.
The main drawback to Superdrol is its highly toxic nature, especially on the liver and heart.
It is one of the highest-risk steroids a bodybuilder can take, thus extreme caution should be used if someone were to use this compound.
Caution: It is generally a bad idea to stack Superdrol with other compounds, conservative doses should be taken and cycles should be kept short.
