ANDARINE (S4)

S-4, better known as Andarine and also referred to as Androxolutamide or GTx-007, is a Selective Androgen Receptor Modulator (SARM). In a notable study conducted by Gao et al., S-4 was characterized as an androgen receptor agonist in orchidectomized rats. The mechanism of action was found to focus on skeletal muscles, bones, and the pituitary gland.

Effects of S-4 on Muscle Mass

Male rats were treated for 8 weeks following castration with either 3 mg/kg or 10 mg/kg of S-4. The study showed that both dosages were effective in restoring muscle mass and strength, both in the soleus muscle and in the levator ani muscle, to levels comparable to those of intact male rats.

Treatment with S-4 had a minimal impact on the weight of the prostate and seminal vesicles, approximately 16-17%. However, strong androgenic effects on the prostate and seminal vesicles were observed.

Furthermore, both dosages exhibited strong agonistic activity in the pituitary gland, resulting in decreased plasma levels of both luteinizing hormone (LH) and follicle-stimulating hormone (FSH) in the castrated male rats. Read more here.

Effects of S-4 on Bone Mineral Density

According to the study by Gao et al., an 8-week treatment with S-4 resulted in a significant increase in bone mineral density in castrated male rats.

In another study conducted by Kearbey et al., female Sprague-Dawley rats were treated to investigate the effects of S-4 on accelerated bone loss caused by ovariectomy. This study concluded that S-4 treatment not only maintained cortical content and overall bone mineral density but also increased bone strength while simultaneously reducing total body fat.

Kearbey et al. also concluded that treatment with S-4 has positive effects on both skeletal muscles and bones. It was suggested that S-4 treatment could reduce the risk of fractures by both increasing bone mineral density and strengthening bones and skeletal muscles, which in turn reduces the likelihood of falls.

Vale is an 8 month pregnant omega working as a waitress at a strip club and a cam girl. She starts to get very creepy vibes from a regular at the club, and her baby daddy ghosted her. She has had an online relationship with a man named Bishop through her cam girl status. One night, bishop was paying to watch her sleep and ansthe creepy regular Andrew break in and watch her sleep he tells vale to come to him at his business now. She flees and finds herself at a large security company with some.hot of alphas who are there to help her. This imegaverse is a little different than I have read, but I am thoroughly enjoying it. Vale is not a traditional omega she was raised by a single beta mom, and the alphas are not normal alphas they have never really loved pack life. But they are ruthless mercenaries. They need her, and she needs them. I love the aspect of the stalker and now the plot twists at the end, so so good. Sometimes, it seemed a little slow and stale mated, but since this a duet, I think It was just her starting to have Vale get to know her alpha suitors. Cliffhanger for sure with this one.

That ending 😫
Format: Kindle
I fell into a false sense of security and really thought this was gearing towards a happy ending. Then I realized there’s no work they don’t punish Andrew. I really liked Vale’s character. I don’t normally read books with pregnancy but going into this knowing she was pregnant made it more enjoyable for me. I loved Bishops devotion to her and her happiness. I also loved that Holt and Mercy couldn’t fight their attraction to her. I love scent matches so very much. I’m so curious to see how this duet will end up. And I need to pay more attention and notice that a book I’m starting is a duet to begin with lol

This should be interesting! She’s gonna run and then what’s his face is gonna grab her. I’m worried! Wow that was a great book and cliffhanger! Loving this!

Baby bumps and bodyguards
Format: Kindle
Dark, emotional, and unexpectedly tender, Not Ready is an omegaverse romance that delivers found family feels, fierce protectiveness, and a very pregnant heroine who refuses to break. Vale’s on the run from a stalker, but lands in the arms of three private security alphas, cue the swoony tension, fake marriage twist, and slow-burn heat. It’s a little gritty, a little soft, and a whole lot addictive. If you love protective alphas, high stakes, and heroines with quiet strength, this one’s a must-read.
