Boldenone is an anabolic steroid. It is made by bonding a undecylenate ester to the boldenone hormone structure. This oily material is boldenone undecylenate in it's raw and unsuspended form. It can be used to mix with sterile oil and solvents like benzyl alcohol, to make into an oil based suspension that can be injected intramuscularly.
Boldenone (Equipoise) lacks the 17AA group but actually has a very long undecylenate ester chain attached instead. This ester chain makes boldenone very oil soluble. Enzymes in your liver will eventually cleave off the ester chain from the boldenone hormone, finally setting it free so that it can interact with androgen receptors in your muscle cells.
Boldenone (Boldenone Undecylenate) has ability to enhance protein synthesis, nitrogen retention in the muscles, inhibit glucocorticoid hormones and increase IGF-1 output. It is primarily equal to the hormone Dianabol.
Boldenone is also well known for increasing red blood cell count, a trait shared by most all anabolic steroids. It doesn't contain the 17AA group that makes Dianabol so short lasting, causing it stays in the body much longer and therefore making it so much more effective for building lean muscle mass and strength.
