The Amount of Pure Un-Esterified Testosterone Left Over
It is important for every person to understand that the ester which is attached to any injectable anabolic steroid possesses a certain percentage amount of the total molecular weight of the molecule. Therefore, for example, 100mg of Testosterone Enanthate is not 100mg of pure Testosterone. The reality is that you are receiving less Testosterone than most of you think, and once the ester has been removed through the esterase enzyme, the amount of pure un-esterified Testosterone left over is very different depending on the ester in question that was previously attached to the hormone.

Long chain esters, such as Cypionate, Decanoate, Enanthate, etc. possess a much weightier molecular weight than short chain esters. Consequently, on a mg for mg basis, you are receiving far extra mg of steroid in a short estered compound as opposed to a large estered compound. As an example, there exists a larger amount of mg of Testosterone in 100mg of Testosterone Propionate than 100mg of Testosterone Enanthate. This is due to the shorter, and therefore lighter weight of the Propionate ester in comparison to the larger and therefore much heavier Enanthate ester. Many individuals just do not realize this, and should always consider this factor as one of the factors involved in the decision making process concerning which ester variant of any given compound to use during a cycle.

Without complex mathematical explanation as to how much of the ester weight is determined to occupy in a given compound, here is a list of some of the most common esterified injectable compounds and how much free hormone is left in a given amount of the compound (standardized to 100mg),

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).

How to do steorids intramuscular injection?
All oil based and water based anabolic steroids should be taken intramuscularly. This means the shot must penetrate the skin and subcutaneous tissue to enter the muscle itself.  So we need to figure out what is an intramuscular injection.
An intramuscular (IM) injection is a shot of medicine given into a muscle. Certain medicines need to be given into the muscle for them to work correctly.
Where can I give an intramuscular injection?
An intramuscular (IM) injection is a shot of medicine given into a muscle. Certain medicines need to be given into the muscle for them to work correctly.
The following are safe  areas to give an IM injection:
  • Vastus Lateralis Muscle (Thigh): Look at your thigh and divide it into 3 equal parts. The middle third is where the injection will go. The thigh is a good place to give yourself an injection because it is easy to see. It is also a good spot for children younger than 3 years old.
  • Ventrogluteal Muscle (Hip): Have the person getting the injection lie on his or her side. To find the correct location, place the heel of your hand on the upper, outer part of the thigh where it meets the buttocks. Point your thumb at the groin and your fingers toward the person’s head. Form a V with your fingers by separating your first finger from the other 3 fingers. You will feel the edge of a bone along the tips of your little and ring fingers. The place to give the injection is in the middle of the V. The hip is a good place for an injection for adults and children older than 7 months
  • Deltoid Muscle (Upper arm muscle): Completely expose the upper arm. You will give the injection in the center of an upside down triangle. Feel for the bone that goes across the top of the upper arm. This bone is called the acromion process. The bottom of it will form the base of the triangle. The point of the triangle is directly below the middle of the base at about the level of the armpit. The correct area to give an injection is in the center of the triangle, 1 to 2 inches below the acromion process. This site should not be used if the person is very thin or the muscle is very small.
  • Dorsogluteal Muscle (buttocks): Expose one side of the buttocks. With an alcohol wipe draw a line from the top of the crack between the buttocks to the side of the body. Find the middle of that line and go up 3 inches. From that point, draw another line down and across the first line, ending about halfway down the buttock. You should have drawn a cross. In the upper outer square you will feel a curved bone. The injection will go in the upper outer square below the curved bone. Do not use this site for infants or children younger than 3 years old. Their muscles are not developed enough.
Steps of Injecting Steroid Oil or Water Based – The Injection Procedure.
  • There are a number of steps that should be understood in order to complete a safe and proper intramuscular injection. First off, before handling any needles or vials, the user should take a thorough shower.
  • Next, an alcohol swab should be used to clean the injection site and another alcohol swab should be used to clean the rubber stopper on top of the vial which will be drawn from. Then, take a brand new syringe out of its wrapper, remove its plastic top, draw about 2 ccs of air into it and insert it into the vial. Inject this air into the vial; this creates pressure within the vial and makes it easier to draw out oil based preparations.
  • Then, turn the vial upside-down and slowly draw out the oil until your quote overdrawn at least 1/4 cc. For example, if someone was going to take a shot of 1 cc, they should pull out approximately 1 1/4 to 1 1/2 ccs of liquid, then tap the side of the case to help get the air bubbles that were drawn into the syringe to come to the top. At that point, the excess 1/4 to 1/2 cc could be injected back into the vial and the needle removed.
  • Then, hold the syringe needle-side-up and continue to tap it to encourage all the air bubbles to come to the top of the syringe. Now, take another clean syringe, remove it from its sterile package and unscrew the needle from the syringe. Exchange the brand new needle for the one that has just been injected into the stopper. By using two needles for every injection, you can take advantage of using the full sharpness of the pin. The needle does suffer some dulling when it is pushed through the firm rubber stopper on a vial. It is important not to touch this needle before the injection. It should not come into contact with a counter top, your fingers, nor should it be cleaned with alcohol. This needle is sterile and should not be touched. At this point, once again swab the injection site with alcohol, then press the stopper of the syringe holding it needle-side-up, until the slight air bubbles that are at the top are pressed out. Once a bead of oil has appeared at the top of the needle, allow it run down the surface of the needle which provides lubrication.
  • At this time, take the syringe and hold it like a dart. Use the other hand to stretch the skin at the injection site and simply push the sharp clean needle in. After inserting it deep into the muscle, pull back on the stopper for a few seconds to make sure it does not fill up with blood which would indicate that the needle had been injected into a blood vessel. Providing there is no blood present in the syringe, slowly press the stopper down until all the oil is injected. Then, quickly pull the needle out and take another alcohol swab and press firmly on the injection site. This will minimize bleeding, if there is any, and by firmly pressing on the injection site and slightly massaging it, some of the soreness may be eliminated. It is important that the liquid is not injected too quickly as this causes more pain at the site during the injection and in the proceeding days.
After this procedure has been completed, return the plastic caps to shield the needles and make sure they are discarded properly.
TIPS: To avoid discomfort and excessive scar tissue at the injection site, it is not wise to inject more than 2 ccs of solution per shot. It is also not prudent to use the same injection site more than twice a week (once a week is preferred) .
