OTR-AC (MK-29, OSTARINE-O-ACETATE)

OTR-AC, also known as MK-2866 Ester, is MK-2866 (Ostarine) that has undergone esterification (the process of combining an organic acid with an alcohol). This chemical process is used to maximize potency and extend the half-life (the time required for a quantity to reduce to half of its initial value) of a substance. Due to this process, the ester version of ostarine has the capacity to remain bioactive ten times longer. This results in benefits such as reduced dosing frequency and more stable blood levels.

How OTR-AC Works 
As the ester version of the selective androgen receptor modulator (SARM) ostarine, OTR-AC is more potent and has longer-lasting effects. By binding to proteins in the body known as androgen receptors, it stimulates the formation of muscle tissue. This, in turn, leads to an increase in muscle mass and strength.

Research on OTR-AC
Increase in Muscle Mass and Strength 
Studies suggest that OTR-AC, along with other SARMs, increases muscle mass and strength by stimulating the formation of muscle tissue:

  • In adult rats, the administration of SARMs, including OTR-AC, resulted in an increase in lean muscle mass and a decrease in body fat percentage.
  • In older male and female rats, OTR-AC administration resulted in increased lean muscle mass, decreased fat mass, and significant improvements in their ability to climb stairs.
  • Studies showed that OTR-AC may help increase muscle mass in rats with cancer cachexia (muscle wasting).
  • In older male and female rats, OTR-AC significantly improved total lean body mass and physical function.
  • In rats that had their ovaries surgically removed, OTR-AC improved muscle tissue.
  • In rats, OTR-AC increased muscle mass by enhancing the production of muscle cells.

Reduction of Body Fat 
Aside from helping gain muscle mass, OTR-AC has also been found to reduce overall body fat:

  • In Phase I and II clinical trials, OTR-AC has demonstrated promising results in increasing total lean body mass, decreasing total tissue fat percentage, and enhancing functional performance.
  • A review of studies showed that OTR-AC can help increase lean body mass and reduce body fat in overweight rats.
  • In a phase 2a study, the administration of OTR-AC along with other SARMs resulted in increased lean fat mass and decreased body fat percentage.
  • In male rats, OTR-AC increased fat cell breakdown by improving lipid metabolism and affecting the release of adiponectin (a hormone that regulates fatty acid breakdown).

Improvement of Bone Health 
Studies suggest that OTR-AC can help stimulate bone formation and protect against bone disorders:

  • In rats that had their ovaries surgically removed, OTR-AC administration resulted in improved bone healing.
  • In a rat model for aged male osteoporosis, both OTR-AC and testosterone treatments improved bone healing by increasing callus volume and area, bone volume and density, and bone width.
  • In a rat model of postmenopausal osteoporosis, high doses of OTR-AC for 5 weeks resulted in increased bone volume, density, and bone mineral density.

 

Reduction of Cholesterol Levels 
Evidence suggests that OTR-AC can help lower cholesterol levels, especially low-density lipoprotein (bad cholesterol):

  • In older male and female rats, OTR-AC administration resulted in a significant reduction in low-density lipoprotein levels.
  • In rats that had their ovaries surgically removed, OTR-AC treatment reduced blood cholesterol levels.

A familiar story, just with…..less.
Format: Kindle
So, as other reviewers make clear, this is very similar to Pack Darling and The Beta. It’s much closer aligned with The Beta, in plot and maybe more like Pack Darling with characters. That being said, I don’t hate this…..but it wasn’t great either. It’s both books mentioned but just….less. Less angst, less emotion, less feeling. The plot feels very half fleshed out, and the “bad guy” feels underwhelming. I didn’t really feel any real emotions from and of the male leads, except maybe Oliver. The others fell sorta flat for me. And Mika makes herself out to be this big bad ass straight outta training and then we never see it from here again with the one fitting room incident as the exception. SPOILER: The whole, “Oh, I’m actually probably an Omega, but I don’t wanna be but I do actually wanna be but no one can ever know my secret that I do nothing to hide “ thing fell so flat. She never commutes to believing she was secretly an omega, but also mentions her “secret” a lot. It just felt so manufactured. I’m intrigued enough to read part 2 and see how the author closes everything out, but this is not one I’ll recommend or ever come back to.

Good start to a series
Format: Kindle
I delayed reading the series for reasons I don’t remember. But my TBR list is huge so I thought I’d take a shot of this and I was pleasantly surprised. I didn’t think the blurb about it was anything special. But it was a very good book. It took some interesting twists and turns. I am so glad the second book is already out. Because I would not have waited patiently. Very slow burn but good storyline. 🔥🔥/5

A good read
Format: Kindle
Multiple points of view. 3 Alpha men and an Omega male. She is a Beta in training for a new program placing betas in Alpha/Omega packs. Mila is only doing the program for the money to take care of her dad. She wasn't expecting to fall for a pack but when she sees this packs Omega she is done for. There is just something about him. His Alphas are good looking as well. Too bad she is hiding a secret and their government is acting shady. I liked it and can't wait to see where their story goes.

Slightly repetitive but I did love some things
Format: Kindle
I love this type of story. And omegaverse is one of my all time favorite genres. But there are a few things that pulled me out of my enjoyment while I was reading. It was repetitive at times as well as struggled with telling not showing. So we didn’t always feel like we were experiencing things with the main character. There were also some plot holes but they may still be answered in part 2. Now this isn’t to be said I didn’t enjoy parts of the story. I loved the almost instant love between Mila and Oliver. And how he started changing around her.
