Testosterone Cypionate

Overview and History

Testosterone Cypionate is very similar to Testosterone Enanthate – they have very similar absorption rates and half lives. Testosterone Cypionate has a half life of 12 days, and Testosterone Enanthate has a slightly lower half life of 10 days. Interestingly enough Testosterone Cypionate is widely preferred by bodybuilders in America. Testosterone itself is one of the safest anabolic steroids because the body creates Testosterone on its own to some extent much like it creates neurotransmitters like serotonin and melatonin. Performance enhancement carries a large stigma in sports, but honestly is simply supplementing more testosterone into the body than it already creates.

Testosterone Cypionate was originally manufactured by UpJohn in the 1950’s. It was released and sold under the brand name of Depo-Testosterone. At first, the name was much longer and listed as Depo-Testosterone Cyclopentylpropionate. Surely you can understand why the name was drastically shortened over time. American athletes throughout the 60’s, 70’s, and 80’s liked using Testosterone Cypionate over it’s alternative of Enanthate – which really, the only major difference between the two was that Cypionate was made in the USA and Enanthate was not. Athletes chose to use the Cypionate simply to support an American made product despite the fact that the two were/are nearly identical with the exception of half life.

Testosterone Cypoinate Dosages

Testosterone Cypinate doses are relatively versatile. Medicinally speaking, someone who has andropause or androgen deficient, the dose is anywhere between 50-400mg every 2-4 weeks. Of course, this will vary depending on how much Testosterone is required to balance the body’s deficiency.

The doses of Testosterone Cypionate are usually divided into three categories: beginner, intermediate, and advanced. The dosages are usually given at least once per week, often more. Beginner Testosterone dosages are around 300-500mg weekly. Intermediate doses are around 500-700mg weekly, but an intermediate user typically needs to be well above 500mg/week. Advanced doses can be anywhere from 700-1000mg per week. Excessively high doses of Testosterone Cypinate are rarely every necessary.

The half life of Testosterone Cypionate is 12 days, so the injections are really only necessary twice per week, evenly spread out. For example, if someone was on the intermediate level and taking 600mg/week of Testosterone, they would get 300mg injected twice per week. This allows for the body to always maintain a steady level of Testosterone and not cause the blood plasma levels to raise and lower too quickly which then results in more severe side effects.

Testosterone Cypoinate Cycles

It’s worth mentioning that Testosterone Cypionate cycles are also versatile, just as the doses are. This steroid is stackable – that is, it is compatible with every anabolic steroid. In fact, Testosterone Cypionate is required when taking any other steroid.

Testosterone Cypionate cycles of varying types are completely possible, including bulking, cutting, and lean mass cycles. You should know that regardless of whether you are a current user or are planning on using Testosterone Cypionate, you will be required to use an aromatase inhibitor during cutting or lean mass cycles. The reason is to eliminate retained water which will make the body look bloated and puffy. The exception to this rule is if the user doesn’t mind appearing bloated, however this is typically something that users wish to avoid.

Some people that take Testosterone Cypionate expect to see immediate results. It takes some patience in order to see optimum results. You have to keep in mind the time duration of cycles. The half life of Testosterone Cypionate is twelve days, which requires an extended cycle length of ten to twelve weeks. The longer period of time needed to reach “peak” or stable blood plasma, the kick-in time where the user will begin to see physical changes is at about four to six weeks into the cycle. You can compare this to anabolic steroids which have a shorter half life, thereby the kick-in period where you would see results is at about 2-4 weeks.

The beginner Testosterone Cypionate Cycle consists of just taking Testosterone Cypionate at 300-500mg per week. This is the most basic anabolic steroid cycle. It’s a great place for people to begin as Testosterone is one of the safest anabolic steroids because the body creates it on its own. Starting off at this level enables the user to gauge how their body reacts to testosterone before they add other compounds.  If someone experience negative side effects from just testosterone, then it’s pretty certain that compounding would cause even more severe reactions.

The intermediate Testosterone Cypionate Cycle consists of taking Testosterone Cypionate at 500mg per week, Nandrolone Decanoate or Deca Durabolin at 400mg per week (both of these taken for weeks 1-12) and for weeks 1-4, the user takes Dianabol at 25 mg per day. The advanced Testosterone Cypionate Cycle, which is also 12 weeks total cycle time consists of: Testosterone Cypionate at 100mg per week and Trenbolone Enanthate at 400mg/wk.
