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.

A Good Value
Size: Small, Color: Black, Size: Small, Color: Black
The suit is a good value. Ordered for senior prom for my son. He is 5’10 athletic build and between 165-170 lbs so we ordered the small since he wanted a slim fit and nothing that would be very loose. The suit fit him great, not too snug , the jacket has a satin finish on the lapel and edge of pockets which gives it an elevated elegant look. The jacket has an interior pocket but the rest are just for aesthetic as they do not open. I did have to cut a small slit in order to use the pocket square. The pants fit like a glove but you may want to size up if you are very muscular. The material is light weight which is perfect for prom season or warmer weather. The vest was oversized but we were not planning to use the vest anyway. Quality: several hanging threads that needed to be snipped but no big deal, the stitching was even and straight and the interior had piping of a complimentary fabric. After a full night of dancing and activities he did not have any issues with stitching breaking or splitting of seams. The buttons are black with a silver edge which give the suit some sophisticated flair but keep this in mind if you plan to style with gold. Overall, I am very pleased with this suit considering it’s price point. It’s perfect for a teen that will attend various senior events. Shipping took 2 weeks so plan accordingly and pay attention to the expected delivery date.

Decent Tux but no customer service
Size: XX-Large, Color: Deep Grey
Decent tux for the money. Wish that we could have ordered different sizes for the jacket and the pants. The vest/jacket fits great but the pants were too big. Ended up having to buy separate pants. The add says that if you email them for a different size, they will help you out, but we never heard anything back from our email.
