Anabolic Steroid Esters

Anabolic steroids, also known more properly as anabolic-androgenic steroids (AAS),[1] are steroidal androgens that include natural androgens like testosterone as well as synthetic substances that are structurally related and have similar effects to testosterone. They are anabolic and increase protein within cells, especially in skeletal muscles. AAS also have varying degrees of androgenic and virilizing effects, including induction of the development and maintenance of masculine secondary sexual characteristics such as the growth of the vocal cords and body hair. The word anabolic, referring to anabolism, comes from the Greek ἀναβολή anabole, "that which is thrown up, mound." They are one of three types of sex hormone agonists, the others being estrogens like estradiol and progestogens like progesterone.


AAS were synthesized in the 1930s, and are now used therapeutically in medicine to stimulate muscle growth and appetite, induce male puberty and treat chronic wasting conditions, such as cancer and AIDS. The American College of Sports Medicine acknowledges that AAS, in the presence of adequate diet, can contribute to increases in body weight, often as lean mass increases and that the gains in muscular strength achieved through high-intensity exercise and proper diet can be additionally increased by the use of AAS in some individuals.[2]


Health risks can be produced by long-term use or excessive doses of AAS.[3][4] These effects include harmful changes in cholesterol levels (increased low-density lipoprotein and decreased high-density lipoprotein), acne, high blood pressure, liver damage (mainly with most oral AAS), and dangerous changes in the structure of the left ventricle of the heart.[5] Conditions pertaining to hormonal imbalances such as gynecomastia and testicular size reduction may also be caused by AAS.


Ergogenic uses for AAS in sports, racing, and bodybuilding as performance-enhancing drugs are controversial because of their adverse effects and the potential to gain unfair advantage in competitive physical competitions. Their use is referred to as doping and banned by most major sporting bodies. For many years, AAS have been by far the most detected doping substances in IOC-accredited laboratories.[6][7] In countries where AAS are controlled substances, there is often a black market in which smuggled, clandestinely manufactured or even counterfeit drugs are sold to users.


100mg Testosterone Suspension (un-esterified Testosterone) = 100mg Testosterone

100mg Testosterone Acetate = 83mg Testosterone

100mg Testosterone Propionate = 80mg Testosterone

100mg Testosterone Isocaproate = 72mg Testosterone

100mg Testosterone Enanthate = 70mg Testosterone

100mg Testosterone Cypionate = 69mg Testosterone

100mg Testosterone Phenylpropionate = 66mg Testosterone

100mg Testosterone Decanoate = 62mg Testosterone

100mg Testosterone Undecanoate = 61mg Testosterone

100mg Trenbolone Acetate = 87mg Trenbolone

100mg Trenbolone Enanthate = 70mg Trenbolone 

100mg Trenbolone Hexahydrobenzylcarbonate = 70mg Trenbolone

100mg Nandrolone Phenylpropionate = 67mg Nandrolone

100mg Nandrolone Decanoate = 64mg Nandrolone

100mg Drostanolone Propionate = 80mg Drostanolone

100mg Drostanolone Enanthate = 70mg Drostanolone


If one wishes to find out the specific weight of a specific amount of esterified hormone, the steps are simple. Let us take Primobolan (Methenolone Enanthate) as an example.We want to figure out how much free Methenolone exists in 750mg of Methenolone Enanthate (Primobolan).


First we must find out the molecular weight of Methenolone itself (UN-ESTERIFIED - this is very important): 302.451 g/mol


We then must find out the molecular weight of the Enanthate ester (when unattached to any molecules, it is properly referred to as heptanoic or enanthic acid): 130.18 g/mol


The two weights must then be added in order to determine the total weight of Methenolone Enanthate: 302.451 + 130.18 = 432.631 g/mol


The total weight must then be divided by the weight of the ester in order to find out how much percentage of the total weight is occupied by the Enanthate ester: 432.631 / 130.18 = 3.3233292364419


This number is our percentage, but it must be multiplied by 10 to obtain the proper figure. We end up with 33% (rounded off).


33% of the Methenolone Enanthate molecule is occupied by the Enanthate ester. We wanted to know how much pure and free Methenolone is left over in 750mg of Primobolan. This is a two-step process, so we must then first subtract 33% from 750mg: 750 x 0.33 = 247.5mg


247.5mg is how much weight the Enanthate ester comprises the 750mg total of Primobolan. If we subtract that number from 750, we get: 502.5mg of un-esterified free Methenolone left over from 750mg of Methenolone Enanthate (Primobolan)
