YK-11

YK-11, also known as myostine, is a Selective Androgen Receptor Modulator (SARM) clinically proven to partially activate the androgen receptor while also acting as a myostatin inhibitor.

A compelling study led by researchers Lee et al. investigated YK-11 as a potential muscle-building and muscle-preserving compound under conditions of sepsis. In the experiment, mice were fed two different doses of YK-11 (orally administered at 350 mg/kg and 700 mg/kg) for ten days. The researchers then examined how these mice responded to a peritoneal injection of E. coli bacteria.

The study demonstrated that YK-11 inhibited the activity of myostatin, a hormone that limits muscle growth in mammals (source). Not only did the mice treated with YK-11 maintain their body mass during the disease phase, but they also had a more favorable fat-to-muscle ratio, indicating less fat and more lean tissue compared to the control group.

Furthermore, the results showed that the treated mice were able to recover lost muscle mass in the back and thighs following exposure to systemic E. coli. Their muscle cells also demonstrated increased resistance to atrophy when compared to those of the control group.

In addition to its impact on muscle mass, YK-11 also affected the immune response to gram-negative bacteria. The treatment with YK-11 led to reduced negative effects of bacterial infections, including a decrease in endotoxins and inflammatory markers in the lungs.

Moreover, there was a significant reduction in biomarkers indicating organ damage, including liver and kidney markers such as AST, ALT, and BUN. The use of YK-11 also appeared to enhance the removal of harmful bacteria from the mice's organs (source).

Lastly, it's worth noting that the study also examined the survival rate during sepsis, and mice treated with YK-11 had a higher likelihood of surviving up to the 72-hour mark. These treated mice showed little to no evidence of bacterial colonization in their vital organs.

Smooth skin without the post-shave itch
I’ve always had issues with my skin feeling super irritated after I shave my legs, so I started applying this Cyperus Rotundus oil right after hopping out of the shower. The quality of the blend is impressive—it’s got jojoba and almond oil too, so it feels very nourishing rather than just sitting on top of the skin. It absorbs quickly enough that I can put on my leggings and head to the gym without feeling like a greaseball. The functionality as a hair inhibitor is a nice bonus. I’ve noticed the hair on my shins seems to be coming back a bit softer and less stubbly than before. For a 55 ml bottle, the value for money is solid since you only need a few drops to cover a large area. It’s a great find for anyone who deals with that annoying sandpaper feeling a day after waxing. My roommate even started using it on her arms because it’s fragrance-free and doesn't mess with her perfume.

Lightweight oil that fits into a simple routine
I started using this oil as part of my regular skincare routine, mainly applying it to areas like my arms and face after showering. The texture feels light and spreads easily without leaving a heavy residue. I noticed it absorbs fairly quickly, which makes it convenient for daily use. It also has a mild scent that is not overwhelming. I like that it includes plant based ingredients, and it leaves my skin feeling soft after application.

Refreshing orange scent
These are effective at refreshing your disposal. When I am done cleaning up my kitchen I put 2 drops in the disposal side of my sink and briefly pulse the disposal to break open the drop. Don't run any water as this will wash away the drop and the fresh orange scent. I am very sensitive to perfume or floral fragrances - these are just the right amount of orange scent to make your drain smell fresh without the scent overwhelming the kitchen.
