Like other AAS, boldenone is an agonist of the androgen receptor (AR).  The activity of boldenone is mainly anabolic , with a low androgenic potency. Boldenone will increase nitrogen retention, protein synthesis, increases appetite and stimulates the release of erythropoietin in the kidneys.  Boldenone was synthesized in an attempt to create a long-acting injectable metandienone , for androgen deficiency disorders. Boldenone acts similar to metandienone with fewer adverse androgenic effects. [ medical citation needed ] Although commonly compared to nandrolone , boldenone lacks progesterone receptor interaction and associated progestogenic side effects.
Undecylenic Acid is an unsaturated carboxylic acid. The molecules of most natural fatty acids have an even number of carbon chains due to the linkage together by ester units. Analogous compounds of odd numbers carbon chain fatty acids are supplemented synthetically. Pelargonic acid, C-9 odd numbers carbon chain fatty acid, is relatively high cost fatty acid. Pelargonic acid can be prepared by o zonolysis which uses ozone is to cleave the alkene bonds. Eexample of ozonolysis in commerce is the production of odd carbon number carboxylic acids such as azelaic acid and pelargonic acid and simple carboxylic acids such as formic acid and oxalic acid. When ricinoleic acid, an u nsaturated fatty acid containing one -OH group, derived from castor oil, is pyrolyzed by heating in the absence of air, it breaks down to give undecylenic acid and n-heptaldehyde. This product has the bifunctionality, odd carbon number and the position of its unsaturated double bond at the end of the chain, makes it a versatile tool for chemical synthesis. It's anti-fungal properties are useful in cosmetics and pharmaceuticals. Undecylenic Acid and its aldehyde are used to formulate perfumes. Undecylenic acid and its zinc salt are used for the treatment and prevention of superficial fungus infections of the skin, primarily tinea pedis as well as relieves itching, burning and irritation.
