Description

S23 – Solution, 600MG (20mg/mL)S23 S23 is an orally available selective androgen receptor modulator (SARM). Originally developed by GTX Inc. as a form of hormonal contraception for men, it exhibits a high affinity for the androgen receptor, with a Ki value of 1. 7 nM. A study published by Jones et al. compared the effectiveness of S23 in both castrated and intact male rats.

S23

S23 is an orally available selective androgen receptor modulator (SARM). Originally developed by GTX Inc. as a form of hormonal contraception for men, it exhibits a high affinity for the androgen receptor, with a Ki value of 1.7 nM. A study published by Jones et al. compared the effectiveness of S23 in both castrated and intact male rats.

Effects of S23 on Fertility

In castrated male rats, the effective dose of S23 in the prostate was 0.43 mg/day, and 0.079 mg/day in the levator ani muscle. In intact male rats, a dose higher than 0.1 mg/day resulted in a suppression of luteinizing hormone (LH) by more than 50%. This dose corresponded with a reduction in prostate size and an increase in the size of the levator ani muscle.

In a study involving intact male rats subjects treated with both S23 and estradiol benzoate (to maintain sexual behavior), no sperm was found in the testes of four out of the six subjects after 10 weeks. Moreover, none of the six subjects reported a pregnancy. Following treatment, infertility was completely reversible; all subsequent mating trials resulted in pregnancy.

Effects of S23 on Muscle Mass and Body Fat

S23 exhibits effects on muscle mass and body fat that are similar to those of anabolic steroids. Research involving male rats revealed that treatment with S23 led to a reduction in total body weight and fat mass. Rats in this study were also administered estradiol benzoate to maintain sexual behavior. Despite the known muscle loss effects of estrogens, the combination with S23 neutralized this effect, resulting in an increase in muscle mass in the male rats.

Additionally, another study indicated that S23 might be effective against muscle loss caused by prolonged use of glucocorticoids. This research also looked at the effects of S23 on muscle atrophy induced by castration. In both scenarios, muscle loss was observed, but the administration of S23 and testosterone blocked the dexamethasone-induced dephosphorylation of Akt. The findings suggest that S23 could be an effective treatment against muscle loss induced by glucocorticoids.

Great book!
Format: Paperback
Wonderful, helpful, insightful. Points out many of the key "sore spots" that can sour a marriage if left unmanaged, and how to address them. Very helpful, whether as a premarital counseling book, a book for the happily married couple, or even for the unhappily married couple willing to set their relationship right. Must read!

Good discussion book to eliminate conflict between couples
Format: Kindle
Use this book as a checklist of things you should discuss with your partner - especially if you're considering or are in a long-term relationship. It explains each topic, why it's a likely source of conflict, how to prevent the conflicts, and includes questions for discussion between partners. Understanding and discussing these topics may not feel romantic and fun, and some of the conversations may be challenging for couples who aren't accustomed to such discussions. Do it anyway though because it will eliminate future conflicts before the conflicts even begin and make your relationship run smoother, last longer, and be a source of relaxation and contentment for you both. I'm speaking from experience here. If you are new to the study of this topic, this book will be extremely valuable for you. If you've already studied interpersonal relationships, preemptive conflict resolution, and collaborative negotiation tactics, it's still a great checklist of topics to discuss with your partner. I'm on this end of the spectrum, hence 4 of 5 stars because I'm familiar with the author's other work and this book didn't contain much new content. As a compact, all-in-one, relationship discussion guide though, it's great and worth reading and having on hand for future reference for new relationships or for when new conflicts crop up.

Great for Everyone!
Format: Paperback
This book is very useful to prepare people for marriage and I would recommend it for teens (even if they're not in a relationship), engaged couples, and even those already married since this provides realistic information about love and that not everything in a relationship is easy. It also helps people understand and attempt to loosely preset chores around the house and understand what to do with the extra money earned that isn't needed for bills. While I was already aware and have read about the 5 love languages, that is only briefly covered in one chapter while the rest provides other information so if you already read the 5 Love Languages book understand that there is a lot more involved in this book than that concept. The concept that I want to highlight in this book that I haven't read about before was the 5 Different Ways to Apologize. Increasingly, I think people need to be aware that what we consider to be a 'sincere apology' isn't necessarily the same as everyone else's though there are 5 of them that are fairly common. I was surprised when I found what I thought to be a sincere apology was listed word-for-word! This concept alone can be applied to anyone you socialize with and I especially recommend this piece if you are having apology problems between your friend, significant other, coworkers, and/or boss. Teens and those single will be able to learn a lot from this book, especially to realize that people, on average, are no longer "falling in love" within two years of the relationship and I think this would help them understand that relationships take a lot of work even when it's not convenient for you. Giving them an understanding of how to be flexible when apologizing and to know that people feel loved according to different love languages will make them more aware of how to improve their friendships and relationships in the future. Finally, there is reinforcement in being willing to do chores even if they're not popular and generally establishing healthy spending habits. I personally found this book to be thrilling and Gary Chapman successfully backs up some of his findings with Psychological research and definitions. I loved it so much that I read it in one sitting and now I'm getting my teen friends and budding couples into reading it. Awesome book; give it a try if you haven't already! (:
