SARMs and Jawline [The Magnum Breakdown]

SARMs and jawline

Selective Androgen Receptor Modulators (SARMs) are a group of drugs that attract fitness enthusiasts for muscle building. Now, supplements containing SARMs are starting to attract men who seek a better jawline. When combined with mewing, it’s possible that SARMs might supercharge your facial aesthetics.

SARMs can potentially close growth plates and shouldn’t be taken before the age of 25. SARMs lead to stronger bones by inhibiting the action of osteoclasts (which break down bone) and promoting the action of osteoblasts (which create new bone). It’s unknown what effect this has on mewing and facial bone growth.

These groups of drugs can slow down osteoporosis. They also work for muscle-wasting diseases, hypogonadism, and cancer.

Athletes use these anabolic agents to build muscle. As the abbreviation implies, SARMs are selective and target only the androgen receptors in the body. That’s why they don’t cause as many side effects as anabolic steroids. Some of these side effects are acne, liver damage, breast enlargement, shrinking of the testicles, hair growth on the upper back, and abnormal menstrual cycles.

Testosterone supplements increase skeletal muscle mass and strength in both men and women. The anabolic effects of testosterone on skeletal muscle mass and strength are related to the dose and the power of the compound. SARMs work similarly to testosterone in that they fill the same androgen receptor.

Androgens in our body protect the bone. But to take them in the form of supplements is not advisable for bone conditions like osteoporosis due to their side effects. Hypogonadism or deficiency of androgens is one of the few clinically indicated reasons for taking them.

Do SARMs Affect Jawline & Facial Bone Growth?

SARMs and other anabolic agents improve aspects of bone remodeling (Kearbey et al, 2007). Bone remodeling is a continuously active process that builds and destroys bone.

Bhasin et al. (2009) stated that SARMs could increase muscle and bone mass. Furthermore, Clarke et al. (2008) discussed that androgens have direct beneficial effects on bone. SARMs and other anabolic agents all have androgenic effects. The question is whether they can target the jaw separately.

Hormones and Bone Remodeling

As we age, our body’s own Human Growth Hormone (HGH) slows down, but supplements can increase HGH. HGH leads to the growth of a broader jawline, hands, and even intestines.

Bone remodeling is a normal process that happens inside the human body. Hormones, including androgens, estrogens, and HGH, facilitate this process. It occurs at a much faster rate with bones that undergo repeated muscle strain. The jaw can be one of them. So we can assume that supplying the body with hormones can cause significant alterations in the jawline.

The hormones mentioned above can potentially lead to a stronger jawline without significantly changing the overall skeletal structure. Normally, bones on the hands, face, and jaw will continue to grow even as you age.

MK-677 (Ibutamoren™)

MK-677 is a supplement that increases levels of growth hormone, and it’s technically not a SARM. Some young adults experience a growth of about 1.5cm from three months of taking it. Its usual dose is 25 mg daily. Some of its effects include increased calcium retention and bone mineralization.

Testosterone and growth hormone can be taken together for tissue repair and growth. Testosterone favors hypertrophy, meaning an increase in cell size. On the other hand, growth hormone increases the number of cells, known as hyperplasia. Taking testosterone and MK-677 together could bring a significant change in bone structure.

When taken at the recommended dose, MK-677 increases growth hormone levels among healthy young adults without serious adverse effects (Nass et al. 2008). Growth hormone will promote both the action of osteoblasts and osteoclasts, leading to improved bone remodeling. 


Over the years, HGH products have become less expensive. More bodybuilders started using them. And now, some findings show that long-term HGH supplementation at higher doses may cause serious adverse effects such as acromegaly.

Acromegaly is a skeletal disorder that leads to cardiovascular and respiratory complications. These complications include cardiomyopathy, a condition where the heart muscle becomes thicker, making it harder to pump blood. Abusing HGH like MK-677 elevates growth hormone levels in the body to an unsafe level (Brennan et al. 2010).

Too much HGH will make you look like Andre the giant wherein your forehead, jaw, and nose all become enlarged.

Acromegaly Progression


Testosterone encourages the growth of skeletal muscles. Some patients undergo testosterone replacement therapy (TRT) because they naturally produce less of this hormone. Without enough testosterone, patients may lose strength while gaining body fat. At improper doses, TRT can lead to gynecomastia or “man boobs.” Testosterone is an Anabolic-androgenic steroid (AAS). These drugs can cause liver impairment and many other adverse effects if taken at high doses.

Mewing and Chewing

One of the best jawline exercises is mewing. What’s fantastic about this facial exercise is that not only does it polish your jawline, but it also offers several health benefits. Mewing promotes proper nose breathing and prevents sleep apnea.

If you were to take a compound that increases bone remodeling, you would want to make sure you also apply the proper stimulus to your bones. Get on a rigorous mewing, gum chewing, and posture-improvement schedule. Otherwise, any increase in bone remodeling you experience will go to waste.

SARMs in the Market

Presently, the SARMs supplements that you see online are legal to buy, but only for research purposes. The SARMs that are sold in capsules as dietary supplements are illegal.

Here are the most common SARMs along with their recommended dosage and potential side effects:

Ligandrol™ 5 to 10 mg daily for 6 to 10 weeks Dry Mouth Headache
Ostarine™ 10 mg to 30 mg for at least 12 weeks Nausea
Back pain
Andarine™ 25 mg in the morning and 25 mg in the evening for 8 to 12 weeks Yellow-tinged vision

testosterone suppression

Testolone™ 5 mg to 30 mg daily for 8 to 16 weeks Sleeplessness, lethargy

The recommended doses aforementioned are applicable for fitness enthusiasts. These doses are ten times higher than those for clinical studies. That’s why taking them is potentially risky for your body.

Athletes taking performance-enhancing drugs such as SARMS can be disqualified from specific competitions. Many amateurs bodybuilders, however, use SARMs just to bulk up.


If you read my previous article, you will learn that there are many other ways to improve your jawline. You may try fillers, surgery, shaping your beard, or even just jawline exercises.

SARMs have been studied painstakingly for more than 20 years now. Yet the US Food and Drug Administration hasn’t approved them for human consumption. As for guys who wish to have a polished jawline, SARMs, when combined with mewing and gum chewing, could potentially work. But you should also explore other, healthier alternatives.
