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.

Half Life

Great for supplemental learning
Format: Paperback
This study guide is an interesting take on drug memorization, though the execution could be better. The coloring concept helps with memory retention, especially for visual learners trying to connect drug names with their uses and classifications. The organization by drug class is logical and helps build understanding of how related medications work. The basic pharmacology information is accurate and the quick-reference format is handy for review. The "made easy" title fits - it breaks down complex medication information into manageable chunks. The coloring activities do help make dry content more engaging, though the quality of the illustrations varies. Some drawbacks: the coloring spaces are sometimes too small for comfortable use, and the paper quality could be better - markers tend to bleed through. Several important newer drugs are missing, and some of the clinical information feels oversimplified. The binding isn't very durable - pages can come loose with regular use. For students, this works best as a supplementary study tool rather than a primary resource. It's helpful for initial learning and quick review before exams, but you'll need more detailed sources for complete medication information. Consider using colored pencils instead of markers, and maybe reinforce the binding before heavy use.​​​​​​​​​​​​​​​​

Cool
Format: Paperback
The concept is amazing! I saw my classmate using this for boards (NPLEX)and I decided to get it. I only used it a few times though and never picked it up again because I suck at memorizing and prefer to just learn it the old school way. It’s cool if coloring is how you study. Maybe using it to wind down from an intense study session.
