Quick Description
S4

▸ Dosage of S4: 600mg (20mg/ml) or 1500mg (50mg/ml)
▸ Improved  strength gains
▸ Improved lean body mass perfect for leaning
▸ Decreased body fat
▸ Does not aromatize (not estrogenic)
▸ Perfect for recomping (losing fat and gaining muscle at the same time)
▸ Increased muscle recovery

As a research chemical, S4 or Andarine belongs to a class of chemicals known as SARMS or selective androgen receptor modulators. Our S4 is made in Canada. Like typical androgens, SARMS bind to the androgen receptor however SARMS create selective anabolic activity.Compared to testosterone and other anabolic steroids and pro hormones, the advantage of SARMS such as S4 is that they do not have androgenic activity in non-skeletal-muscle tissues.

S4 was designed for treatment of conditions such as muscle wasting, osteoporosis and benign prostatic hypertrophy, using the non-steroidal androgen antagonist bicalutamide as a lead compound.

As an orally active partial agonist for androgen receptors, Andrine is effective in not only maintaining lean body mass but actually increasing it.

How does it work?

Selective androgen receptor modulators (SARMS) bind to the androgen receptor and demonstrate osteo (bone) and myo (muscular) anabolic activity. Binding and activation of the Androgen receptor alters the expression of genes and increases protein synthesis which ultimately builds muscle. SARMS such as S4 can cause muscle growth in the same manner as steroids, however unlike testosterone and other anabolic steroids, SARMS (as nonsteroidal agents) do not produce the growth effect on prostate and other secondary sexual organs. SARMS not only represent a new potential treatment option for a wide spectrum of conditions such as muscle wasting diseases (from age-related to AIDS or cancer-related), but they also have immense potential for muscle building for Bodybuilders, fitness and athletes. S4 in particular binds to the androgen receptor in muscle and bone to a third of the affinity of Testosterone.

Evidence of S4 Abilities?

S4 or Andarine (3 mg/kg/day) was also able to restore skeletal muscle and strength in castrated rats, important and applicable for the treatment of muscle wasting and male HRT.

A 120-day study comparing SARM S4 and dihydrotestosterone (DHT) treatment in ovariectomized rats demonstrated that S4 was able to maintain bone mass and bone strength to the levels of intact controls and exhibited greater efficacy than DHT.

Andarine also demonstrated the ability to improve skeletal (soleus) muscle strength, increase lean body mass, reduce body fat, and prevent bone loss.

Losing Bodyfat (Cutting)

Cutting is the environment where S4 truly shines. Certain steroids are considered “cutting” steroids such as Winstrol and Anavar. These steroids don’t offer too much in large gains in muscle mass but are very effective in leaning out the body. The SARM Andarine has very similar properties. The presence of androgen receptors in human preadipocytes and adipocytes suggests that androgens may contribute, through regulation of their own receptors, to the control of adipose tissue development. As S4 shows this binding affinity to the AR, it demonstrates the similar fat burning effects. S4 also shows a decrease in LPL (lipoprotein lipase) which is an enzyme that causes lipid accumulation. S4 also fits into a cutting protocol for the concurrent reduction in body fat with maintenance of muscle mass in a hypocaloric environment.

One of the most disheartening outcomes of cutting is the loss hard earned muscle mass. The drop in metabolic rate and hormone levels (T3, IGF, Testosterone etc) with the lack of calories is a perfect catabolic environment for loss of muscle tissue. As S4 has both anabolic and androgenic effects in muscle tissue, it will not only help with fat loss, but maintain and even increase muscle mass when cutting.

Andarine causes increases in vascularity and promote a very nice, “quality”, hard look to the users muscles, with little or no water retention.

In this way S4 can be compared to Winstrol, without the harsh hair loss or extreme adverse effects on cholesterol.

Also other popular steroids/Prohormones used for cutting such as winstrol or epistane can have a notable effect on drying out of the joints. S4 doesn’t suffer such consequences so the athlete is still able to lift heavy in order to maintain/increase muscle mass and strength.

Another advantage Andarine offers for cutting is that it doesn’t give the painful pumps associated with other popular steroids/Prohormones. Back and calf pumps are particularly detrimental for cutting as it limits the ability to perform cardio.

S4 Dosing for cutting

A 50mg dosing protocol for 6-8 weeks is ideal for cutting purposes for the majority of users.

However due to the vision side effects, if running at these doses some like to follow a 5 on 2 off protocol where S4 is used for 5 days followed by a 2 day break (then this cycle is repeated).

Recomping

The recomping effect of losing fat and gaining muscle at the same time is what the majority of users are looking for. Trying to achieve this when you are not absolutely new to training is extremely difficult. One of the most important factors of recomping is time. As you are trying to achieve multiple objectives, it requires a longer time period to notice good recomp effects so even when running steroids, these would have to be longer run injectable compounds as oppose to the short run liver toxic oral steroids.

Although S4 is taken orally, it is not methylated and is not liver toxic like other AAS/PH/DS’s. As it prevents this side effect and many others, it can be ran for 6 weeks, sufficient time to get a good body recomp.

Dose

A dosing protocol of 50-75mg for 4-8 weeks will give good recomp effects

Diet must also be optimized to where calories are just above maintenance with at least 30% coming from lean sources of protein to get the best recomp effect.Of course, the recomp effects could be even greater if stacked or combined with a more anabolic SARM such as Ostarine.

Strength gains and Lean mass gains

Due to its androgenicity in muscle tissue, Andarine is a good agent for increases in strength without bloat and large increases in weight. Dosing at 50mg is the sweet spot for such gains. Also due to its anabolic nature, these strength gains will come with associated gains in lean mass,.

With all dosing protocols, as the half life of S4 is 4 hours, splitting up the dose into multiple applications is advised.

Also due to this short half life, users have found that taking one of these doses pre WO will offer increased performance in the gym.

S4 and estrogen concern

SARMS cannot be aromatized, conferring all their effects to AR binding and not to metabolic conversion to active androgens/estrogens. Unlike Ostarine where blood work from users has shown a slight elevation in serum estradiol levels, S4 does not show any such elevation. As it has slight androgenic activity, it in fact gives the opposite effects and reduces bloat and other estrogenic effects. This is evident with the aforementioned hardening effects that S4 gives.

RAD140 gives me the kind of result I typically would expect with something like Anavar or Tbol - lean gains and a little increase in strength. It doesn't bloat you like Dbol, but you also don't get that same kind of bulk-result. I use SARMs and supplements purely to heal more efficiently for athleticism, and not for bodybuilding / size. The MK677 is on-point - find I sleep shorter periods and still feel rested, I'm generally in a better mood on waking, and I find I'm able to perform in the gym again for same/similar movements within a day or two instead of needing 3-4 days recovery. AdvancedResearch is the 3rd company I've tried for SARMs, and it's the one I go back to. The rest were fine, but the prices, the quality, and the service when you need help with anything is fantastic!

First time with Bromantane. Compared with basic herbal nootropics, this is a great supplement to a solid daily routine. I find that I am able to think more clearly and even if I feel tired, this doesn't "wake me up" like caffeine does, instead it allows me to think properly and see connections, etc. regardless of how tired I am. Would definitely recommend if you have to perform cognitive tasks all day. As far as this brand, I've had several interactions (and orders) now and it has always been positive!

Canada post crushed a bottle during shipping. They proceeded to send me out another one asap for free. The SR9009 seemed to be getting used up a bit quicker then the other two even with the recommended doses and I contacted them and they gave me a deal on my next purchase. Super quick message responses for any concerns or questions.

Absolutely 5 star company/products.

par le passer javais essayer du Rad140 d'une autre compagnie qui ajoutais de la saveur a leur melange.. et les resultats etait pas a la hauteur de mes attentes et javais plus d'effet secondaire . Avec celui de Advanced Research Chemical ce fut une experience totalement differente. Gain de force incroyable rapidement, excellente pompe musculaire. Alex ma tres bien conseiller sur la quantite a utiliser. ce qui permet de faire 6 semaine environ avec une bouteille de 20mg. ce qui est donne un excellent rapport qualite prix.

Amazing results for someone new to sarms, most noticeable was fat loss benefits, muscle strength and anti catabolic with muscle wasting. Took 25mg daily , no sides whatsoever, blood sugar within normal range, prolactin no issues, hunger is mangeable, lethargy subsides after 3weeks. Worth trying even if standalone.

It will be 2 weeks this Thursday of my 1st cycle and I've gone from 158.4 lbs to 170 lbs in 11-12 days. My strength is also soaring my incline bench was 205 now 245. No side effects that I have noticed. But be prepared for a much larger grocery bill as you will be eating ALOT. I'm almost half way through my 1st cycle and I'm 100% will be doing a 2nd.

Fantastic products and company to deal with. Super fast shipping (usually same or next business day) and fair pricing and discounts.

I recently bought a stack of RAD140 and SR9009. Near middle of the cycle, I noticed the SR9009 level was not matching the RAD even though I was dosing both at 1 ML / day. Mentioned this to them (I might have dosed the SR9009 wrong a few times so wasn't sure if it was my mistake or theirs), they insisted I send them pictures of the bottles. To my utter amazement, Alex emailed me saying he was sending me a replacement SR9009 bottle at no charge shipping and all.
All I can say is, forget the rest of the so-called SARM dealers, these guys are the one and only I will ever deal with. Thanks Alex and Co!

I ordered the lean stack but received the bulk stack instead.Not a bad thing as I am already lean and need to add mass. Customer service is awesome and they insisted on sending me the GW free of charge. So glad I chose this company. I haven't tried the rad140 yet but I tried the mk677 and the only thing I noticed was I got a lot of deep sleep last night and woke up refreshed. No increase in hunger but I took it before bed so maybe that's why. My abs also look more visible too but that's probably unrelated. Will review again once I try the rad140 and cardarine. Definitely will buy again from these guys.

The service rep on messenger listed the possible side effects and he did not hold back, my research confirmed everything he said. I am on my second week of the leaning stack, the body fat is dropping fast and my strength is insane which shows to me that the product is working as usually when I am in a caloric deficit I feel very weak and I do not feel a pump. Thank you for guiding me through this process. ARS has given me the strength to go through this and I am very thankful.
