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.

Best sunscreen
I really like this sunscreen. It feels lightweight on the skin and blends in easily without leaving a white cast, which is a big plus. The texture is smooth and moisturizing, but it does not feel oily or heavy. It works well for daily use, especially under makeup, and feels comfortable even on sensitive skin. The SPF 50 PA++++ protection gives good peace of mind for everyday sun exposure. I also like that it has hyaluronic acid and collagen, so it feels more like skincare than just sunscreen. Overall, it is a great affordable Korean sunscreen and I would definitely recommend it.

My honest review
Lightweight Protection with No White Cast I am very satisfied with this sunscreen. The texture is lightweight, it absorbs quickly, and it truly leaves a "no-cast" finish—without that white layer that many sunblocks tend to leave behind. Plus, it feels hydrating thanks to the collagen, so it works beautifully under makeup or on its own for everyday wear. It offers excellent SPF 50+ PA++++ protection against UVA and UVB rays and leaves no greasy residue. The size is convenient for carrying in a bag or taking along on trips. After using it for several days, my skin feels protected, soft, and comfortable, even in hot weather. I would definitely buy it again and highly recommend it to anyone looking for a lightweight, hydrating sunscreen with a natural finish.

I'm impressed
I'm delighted with this sunscreen. It has a super light texture that absorbs quickly and does not leave a greasy feeling, which is perfect for everyday use, even under makeup. It fulfills what it promises: it does not leave white residue, something that I value very much, especially in photos or when going out in the sun. In addition, it feels quite moisturizing thanks to collagen and hyaluronic acid, leaving the skin soft and with a natural finish

Love it
This has become my everyday sunscreen and I genuinely love it. It’s lightweight, super hydrating, and doesn’t leave that greasy feeling most sunscreens do. It blends in beautifully and sits perfectly under makeup, which is a must for me. I also have sensitive skin and this hasn’t caused any irritation or breakouts at all. It just feels smooth, comfortable, and easy to wear daily. One of those products you actually look forward to using.

Don’t buy
All it did was moisturize and it’s super thing and just liquid. I highly doubt this is actually protecting my skin from the sun. Leaves no cast at all though
