Today we are focusing on 3 products; GH Booster MK 677, Myostatine YK 11 and our famous Test Booster Rad 140

Sarms America’s GH Boostr MK 677

Ibutamoren, also known as MK-677 is a human growth hormone releaser, which means it elevates your natural growth hormone.

It has the same effects of HGH meaning it can be used for longevity, anti-aging, and improving your mood.

It is also very good for healing an injury and is a long term fat burner.


Sarms capsules are taken orally and have no funny after tastes like liquid Sarms do.

Our GH Booster is a growth growth hormone secretagogue. 

A secretagogue is the term for a substance that chemically signals for the pituitary gland to secrete growth hormone. In other words, MK-677 could be compared to peptides like GHRP-6 or Ipamorelin, only it doesn’t require any injections nor does it have any side effects like GHRP-6.

This GHS (Growth Hormone Secretagogue) was developed in an aim to combat such conditions as muscle wasting, obesity and osteoporosis. It was also targeted towards treatment of elderly hip fracture patients, so there are a myriad of studies done on safety.



GH BOOSTER MK677 Ibutamoren (15mg)

Growth hormone pulse intensity can be increased through 4 possible mechanisms:

1- Increasing GHRH (growth hormone releasing hormone) release.
2- Amplifying GHRH signaling in somatotrophs of the anterior pituitary gland.
3- Reducing somatostatin release (somatostatin turns off GH release).
4- Inhibiting of somatostatin receptor signaling.

Mk-677 was found to work through all four of these mechanisms.

After ingestion, Growth Hormone (GH) was shown to increase dose dependently, at doses starting at 5 milligrams (mgs) a day.

In a study on its effects on catabolic states, a once daily oral dose of 25mgs was given to healthy young men subjected to short-term diet-induced nitrogen wasting. After 7 days of this dose, the subjects showed a sustained increase in serum concentration of IGF-1 and Growth Hormone; in addition, the nitrogen wasting was reversed, showing great potential for treatment of conditions involving muscle wasting.

Trials testing the effects of this GHS on fighting obesity showed an increase in lean body mass, but neither total, nor visceral adipose tissue was effected. This study gave subjects 25mgs of MK-677 per day for 8 weeks. The subjects showed an increase in basal metabolic rate after 2 weeks, and an increase in serum levels of GH, IGF-1 and IGF-1 binding protein-3. Increase in lean body mass was hypothesized to be caused by an increase in calorie deposition into the muscle and appetite decrease as opposed to reducing fat storage directly.

A study done for the treatment of osteoporosis and bone mineral density showed some increase in bone density, so there is a true impact on bone mineral density. This can help with injury recovery during your cycle.

Other possible benefits of MK-677 are associated with

  • improved sleep,
  • improved complexion,
  • increase in energy levels,
  • increase nitrogen retention,
  • increase strength and an improved sense of well being.

In addition, some studies also suggest that an increased immune system response was caused by Mk-677, meaning it boosts the immune system to a degree.

In a multitude of studies, Mk-677 increased IGF-1 levels by between 39-89%. To give you an idea of what IGF-1 does, here are some IGF-1 benefits:

  • Increased Fat Oxidation (fat loss).
  • Increased Muscle gains (lean mass).
  • Tightening up loose skin.
  • Healing old injuries.
  • Healing Bones, Tendons and Ligaments.

Sarmsamerica Myostatine YK-11

Myostatine YK-11 is one of the strongest muscle building Sarms available.

This Sarm is a Myostatin inhibitor which can bring huge muscle gains. It is often combined with LGD-4033 ligandrol to achieve steroid like results.

YK11 induces muscle cells to make more follistatin (more than DHT does) – a strong myostatin inhibitor.


YK11 works through the androgen receptor. With that said, YK11 can be as good as testosterone in terms of muscle strengthening, but minus the detrimental side effects.

YK-11 is a powerful SARM supplement promoting massive lean muscle gains, which is a great benefit for those wanting to have an aesthetic and shredded physique.

It basically means that YK11 actually induces muscle cells, causing them to make more follistatin. This is way more then when compared to DHT which is a very strong myostatin inhibitor.

YK11 also works through the androgen receptor as well so this is something else you need to keep in mind when you are using them for the very first time. That being said, YK11 is as good as testosterone when you look at how much strength it can add to your muscles and it does not give you any of the detrimental side effects as well.

YK11 is far more anabolic and androgenic when compared to another popular solution, DHT. DHT is a steroid dihydrotestosterone and it comes with some adverse side effects. This can include hair loss and even prostate enlargement but with YK11 you don’t get any problems like this at all.

In fact, some studies have shown that YK11 can actually help you to grow more hair and the prostate hasn’t changed at all in the trials that have been done so this really is a positive sign.

Dosage should be between 5-10mg per day.


Testolone, also known as RAD-140 is a very powerful Sarm to help you burn fat and build lean muscle. Also great to use for your cutting phase





Sarms America's Test Booster has a major advantage over anabolic steroids in that it offers similar positive results with barely to no side effects at all. 

It is indeed a unique compound even when it is compared to other Sarms products. For instance, it has been proven that Rad 140 testolone has the a unique property of countering prostate enlargement cause by testosterone use, which in effect makes it a perfect stacking agency for high androgenic steroids that can cause this awful undesired effect. 

Testosterone is considered as the perfect comparison template in terms of androgenic and anabolic effects of different compounds, where a ratio of 1[00:10]0 is the baseline. In this regard, RAD140 has an impressive ratio of 90:1.

This means that it is almost as anabolic as testosterone is, but it lacks the androgenic effects, which is a very positive thing, since most of the side effects associated to steroid use come from their androgenic effects.

In addition to that, it has been determined that you would need 40% more of testosterone for the same muscle growth as with RAD140, and yet it would take 60 times more of RAD140 to even start showing any prostate related side effects.

Regarding the affinity to androgen receptors, studies have shown that it has approximately 30% of the affinity seen with testosterone, and almost the same affinity as dihydrotestosterone (DHT).

The recommended dosages of RAD140 vary from 20 to 30 milligrams (mgs) per day, and the optimal cycle duration is 12-14 weeks.
