Andarine S-4

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.

Durable
Color: S6-muti-color
The balls are great for chewers. The squeaky didn’t last long but they are perfect for the ball launcher.

The squeeker isn't durable, but the balls themselves are.
Color: S6-muti-color, Color: S6-muti-color
I have two 70+lb, ball obsessed dogs (a field bred Golden Retriever, and an Old Time Scotch Collie), and these balls are living up to the abuse they're receiving. In the fall we always lose a ball or two in the yard due to getting lost in leaves or longer grass, so I always try and buy a multi pack at the start of the season, so went with these this year. I'm glad I did. Great price for a 6 pack, they fit the medium Chuck-It launcher (a little loosely, but they throw just fine), have great bounce, they FLOAT (which means I didn't lose any at the beach), and they're super durable to the dreaded "mouth squish." The squeaker dies pretty quick, like, within a day, but it isn't the kind that can fall out or choke your dog, so no worries there. The boys are happy, I'm happy, my wallet is happy - I've already ordered another pack.

Disappointed
Color: S6-muti-color
These were great for about 20 minutes then they stopped squeaking...we have 2 left that I have saved but the other 4 do not squeak anymore...disappointed as my dog loves to squeak things...would not buy these again...My dog is only an 8lb dog too...but he can still play with the balls without the squeak...
