Some data has also shown S4 to directly increase lipolysis (fat loss) although it is unclear how significant this affect is.
Andarine, commonly known as S4, is a Selective Androgen Receptor Modulator (SARM) developed by GTx. Like all SARM’s S4 was developed in the treatment of muscle wasting diseases with benign prostatic hypertrophy treatment also being high on the list of possible treatment benefits. Andarine is not as strong as some of the other SARM’s in terms of an anabolic effect that leads to the promotion of lean muscle tissue increases, but it does appear to have other benefits that can prove to be highly valuable. Being an effective SARM, like most SARM’s it is relatively side effect friendly with most users making it an increasingly common option for performance enhancing athletes.
Andarine (S4) Function and Traits
Anadarine (S4) is a SARM, specifically a medication that binds firmly to the androgen receptors. Unlike an anabolic androgenic steroid, S4 focuses only on the bone and muscle sites unlike other androgenic compounds that may affect secondary sex organs. By binding to the androgen receptors, S4 alters the gene expression, thereby increasing anabolism via increases in protein synthesis. Although a highly effective compound, in comparison to its binding affinity it is approximately one third that of testosterone.
Andarine (S4), unlike many androgens, does not convert to dihydrotestosterone (DHT) and it does not aromatize. Aromatization refers to the conversion of testosterone to estrogen. This makes S4 a bit more appealing on a functional basis compared to other androgenic compounds as negative DHT and Estradiol effects cannot occur with this compound. In fact, S4 has been shown to block DHT from binding to the prostate receptor sites.
S4 is based off of the same template molecularly as the drug Bicalutamide, an anti-androgen. However, unlike Bicalutamide, the severe negative effects of that drug are not present with Andarine – while a similar template it is not the same drug.
Effects of Andarine (S4)
The effects of Andarine (S4) can range from bulking to cutting and total body transformation; however, bulking (muscle/mass gains) will be the weakest of the three areas. S4 is not known for packing on a lot of lean muscle tissue, but lean gains can and should be made providing enough calories are present along with muscular stimulation (exercise). For the off-season athlete looking to really pack on size, this is not a product they’ll want to base their plan around although it could be a solid addition to a plan, simply not a standalone item. Andarine is well known for aiding in strength increases. Increasing strength can be a benefit when trying to grow as it allows the individual to lift heavier weights. However, strength and size do not always go hand-in-hand and cannot be used as a gauge when trying to grow. It is very possible to gain little to no weight and still increase strength despite no increases in size.
Cutting will be where Andarine (S4) really stands out and for several reasons. The primary objective of any cutting plan is to lose body fat. In order to lose body fat one must burn more calories than he consumes, which will put lean muscle tissue at risk. S4 supplementation can provide the means to protect muscle tissue during a calorie deficit. The more tissue that’s preserved, the stronger the metabolism will continue to burn. If tissue is lost, the metabolism can slow making fat loss more difficult. Some data has also shown S4 to directly increase lipolysis (fat loss) although it is unclear how significant this affect is. Equally beneficial to the cutting plan, Andarine has been shown to increase hardness and definition significantly in a lean physique. Hardening and strength effects of this SARM have often been compared to the anabolic steroid Winstrol (Stanozolol). As an added bonus, with the strength increasing traits of S4, while strength may not increase when cutting, if using this SARM you may very well find you maintain a lot more of your strength that would have otherwise diminished.
For the every day fitness enthusiast, this may be one of the best SARM’s on the market. It’s not possible to gain a massive amount of muscle and shred up with any product. If you want to go to the extreme in either direction, you have to pick one direction at a time. But if you’re looking for more of a transformation, not necessarily large increases in size or ripped to the bone but more of a beach body look with increases in athletic performance, this is one of the better SARM’s available. Due to the side effect friendly nature, it’s also one of the more appealing.

Side Effects of Andarine (S4)
The side effects of Andarine (S4) are not extensive but some negative effects are possible. The most bothersome side effect of S4 is that of vision disturbances. This is not something that will occur with all users, but of all the side effects of Andarine it is one of the more common. Blurred vision, especially at night and a yellow tinting of the eyes are all possible with this SARM. However, such effects should clear away almost immediately (a few days) after use is discontinued.
estrogenic side effects of Andarine (S4) should not occur as the SARM does not aromatize (conversion of testosterone to estrogen). Gynecomastia (male breast enlargement), water retention or high blood pressure due to severe water retention should not occur with this SARM. However, some data has shown the SARM to promote slight increases in serum estradiol levels, although not significant enough to create estrogenic side effects associated with some anabolic steroids.
There should be no androgenic side effects of Andarine (S4). Hair loss, acne and virilization symptoms in women (masculine trait promotion) are impossible with this medication. Although S4 does bind to the androgen receptor, it only activates in the bone and muscle target areas and not others associated with androgenic issues.
No cardiovascular side effects of consequence have been noted due to the use of S4.
 Testosterone Suppression:
The side effects of Andarine (S4) will include the suppression of natural testosterone production. The rate of suppression will not be as significant as with an anabolic steroid, but may be more significant than with other SARM’s. How much suppression exists will be dependent on dose and genetic factors. Post Cycle Therapy (PCT) may or may not be needed. If used with an anabolic steroid it will certainly be needed.
Andarine (S4) is taken orally, normally in liquid form although capsules are also available. The common dosing range of S4 is 50-75mg per day taken evenly throughout the day. S4 carries a half-life of approximately four hours. Results may be seen in as little as four weeks, but most will find six weeks to be the minimum time frame for decent results to be seen with 8-10 weeks being fairly common. Andarine can be stacked with other SARM’s, with anabolic steroids, peptides or nearly any performance based medication. Some will choose to take it in between steroid cycles as they are attempting to let testosterone levels recover; however, note they will not recover when this SARM is in play.
Availability of Andarine (S4)
S4 is perhaps the most commonly found SARM on the market. Numerous research supply companies or research chemical companies sell the SARM. Some steroid suppliers will also carry the SARM but this is not as common. SARM purchases are techniqually illegal to make unless for research purposes.
Buy Andarine Online
You can buy Andarine online from numerous research supply and research chemical companies. An online purchase is not only the most common but the only option for most individuals. Research companies are able to sell SARM’s and other non-controlled items due to a gray area in the law. Such a loophole does make the purchase legal in the U.S. but it is a thin line and could be made into an issue should law enforcement truly wish to make it one. Before you buy Andarine online or any SARM, you will need to have a full understanding of the law in your country.
Andarine (S4) is a solid SARM if the user understands its purpose. For gains in size it’s not a good choice but for the cutting athlete or one looking to increase strength it is a viable and worthwhile consideration. However, due to the possible vision issues during use, this can make it one of the more unpleasant SARM’s to use. How likely or how severe such issues may be is highly genetically dependent.
