Overview and History of TESTOMED C 250 (Testosterone Cypionate)
TESTOMED C 250 (Testosterone Cypionate) is one of the many esterified variants of Testosterone available. It is the second most popular esterified variant on the market (the first one is Testosterone Enanthate). It is an injectable form of Testosterone hormone with a slow rate of release and a longer half-life. TESTOMED C 250 (Testosterone Cypionate) is very similar to Testosterone-Enanthate, actually, they're very much identical and the two compounds are easily interchangeable (for example, the user can easily run a 10-week cycle of Testosterone and switch between Testosterone Enanthate and Testosterone Cypionate seamlessly). TESTOMED C 250 (Testosterone Cypionate) possesses a half-life of approximately 12 days while Testosterone Enanthate possesses a half-life of approximately 10 days. Testosterone Cypionate is the most commonly prescribed testosterone in the United States. This anabolic steroid is very popular among American bodybuilders and athletes over the Enanthate variant. It must be noticed that neither variant possesses any advantages over the other.
Testosterone Cypionate was first introduced to the market in the mid-1950s and was released on the prescription drug market under the brand name Depo-Testosterone and manufactured by UpJohn (it's a brand name at first was labeled as Depo-Testosterone cyclopentyl propionate and later was shortened). While Testosterone Enanthate is mainly an international product, Testosterone Cypionate is known to be the US answer to the Enanthate variant and usually is an American product. Testosterone Cypionate is produced by Upjohn (who merged with Pfizer in 2009) and is still in production.
The fact that Testosterone Cypionate was the American response to the international product Testosterone Enanthate, many American bodybuilders and athletes throughout the 1960s, 70s, and 80s preferred the use of Testosterone Cypionate over the Testosterone Enanthate because they wanted to support an American product. Nowadays Testosterone Enanthate is utilized in the US almost just as equally as Testosterone Cypionate. In the medical field, TESTOMED C 250 (Testosterone Cypionate), the same like Testosterone Enanthate, is used primarily for the treatment of androgen-deficient male patients (hypogonadism and andropause). Also, TESTOMED C 250 (Testosterone Cypionate) can be used in the treatment of individuals deficient in bone density and strength, treating uncontrollable menstrual bleeding (menorrhagia), osteoporosis treatment, treatment for frail elderly patients and individuals recovering from periods of extensive muscular atrophy. Recently, both Testosterone Enanthate and Testosterone Cypionate were used as a male birth control drug at a dose of 200mg weekly. Testosterone hormone itself is a very powerful androgen unsuitable for use in females and children where other more suitable anabolic steroids (such as Anavar and Primobolan) should be used instead.
Chemical Characteristics of TESTOMED C 250 (Testosterone Cypionate)
Basically, TESTOMED C 250 (Testosterone Cypionate) is simply Testosterone with the Cypionate ester bound to the Testosterone chemical structure. ‘Cypionate’ is Cypionic acid, but once that is bound to Testosterone it is properly referred to in chemistry as an ester bond (or ester linkage). Cypionic acid is chemically bound to the 17-beta-hydroxyl group on the Testosterone structure. Comparing to un-esterified Testosterone, esterified anabolic holds a greater degree of solubility in fats, that results in release slower from the injection site. Anyway, this is not the main reason why esters extend the release rate and half-life of the given anabolic steroid it is attached to. The main reason for the augmentation of its half-life and release rate is due to the fact that when Testosterone Cypionate enters the bloodstream, enzymes will bind to the Testosterone Cypionate molecule and break the bond between the ester and the hormone, which takes a varying amount of time depending on the size of the ester in question. This is the reason why larger esters such as Cypionate, Enanthate, Decanoate, and others all possess longer half-lives than the smaller shorter esters such as Propionate, Phenylpropionate, Acetate, etc. In the end, the ester is removed from the hormone via enzymes, and what is left over following this chemical interaction is pure Testosterone hormone that is free to do its work in the body. This process of enzymes cleaving off the ester from the Testosterone molecule is what is ultimately responsible for the slower release rates. Pure Testosterone alone with no ester bonded to it possesses a half-life of approximately 2 – 4 hours. When the Cypionate ester is attached to it, creating Testosterone Cypionate, the half-life of Testosterone is now extended to 12 days, which results in a slower release and activity of the hormone.
Properties of TESTOMED C 250 (Testosterone Cypionate)
TESTOMED C 250 (Testosterone Cypionate) expresses all the properties of Testosterone, with the exception of the differing release rates and half-lives. Testosterone itself is very much the original anabolic steroid, which is manufactured endogenously naturally in all humans and in the vast majority of animal species. Testosterone is considered the safest anabolic steroid for use because that is already manufactured by the human body and our body is already accustomed to the effects of Testosterone only to a lesser degree. When Testosterone is used for the purpose of physique and performance enhancement, that is simply the supplementation of additional Testosterone – this could easily be defined as the practice of administering (either through injection or ingestion) more of a hormone into the body that it already manufactures and utilizes.
TESTOMED C 250 (Testosterone Cypionate) Side Effects
TESTOMED C 250 (Testosterone Cypionate) is an extremely well-tolerated hormone for most men. When it comes to the side effects of TESTOMED C 250 (Testosterone Cypionate) they could be described as being moderate. TESTOMED C 250 (Testosterone Cypionate) is a Testosterone variant and therefore will carry with it all of the side effects known to Testosterone. Testosterone is the primary male hormone manufactured in humans and in all vertebrates and is known as the father of all anabolic steroids.
The side effects of TESTOMED C 250 (Testosterone Cypionate) are in many ways easy to control. Of course, total dosing, genetic predispositions, individual body reaction, age, sensitivity, and the overall state of health must be taken into account. All factors determine whether someone may experience certain side effects at a greater or lesser degree, or whether they may not experience these side effects at all.
Estrogenic side effects are the first and primary concern that almost all anabolic steroid users consider and research while using TESTOMED C 250 (Testosterone Cypionate). The same like all other testosterone compounds, TESTOMED C 250 (Testosterone Cypionate) carries a high level of aromatase activity: aromatization referring to the conversion of testosterone into estrogen. As estrogen levels rise, this can lead to gynecomastia (male breast enlargement) and excess water retention. This excess water retention can even negatively affect blood pressure. Also, TESTOMED C 250 (Testosterone Cypionate) can have dihydrotestosterone (DHT) related side effects such as acne, hair loss (in case men predisposed to male pattern baldness) and prostate enlargement.
TESTOMED C 250 (Testosterone Cypionate) is an androgen, therefore users also can experience androgenic side effects. Testosterone hormone is known for its reduction to a much more powerful androgen, Dihydrotestosterone (DHT), in the body – particularly in higher degrees in various tissues, such as the scalp, prostate, and skin. Potential androgenic side effects include increased oily skin (sebum secretion), increased acne formation (linked to sebum secretion), bodily and facial hair growth, and the increased risk of experiencing male pattern baldness (MPB) if the individual possesses the genetic predisposition for it.
TESTOMED C 250 (Testosterone Cypionate) is absolutely no hepatotoxic (liver toxic). It is crucial to understand that during the usage of Testosterone, the body stops manufacturing its own natural endogenous Testosterone. Other potential side effects that follow TESTOMED C 250 (Testosterone Cypionate) use include negative cardiovascular impacts, most notably the reduction of ‘good’ (HDL) cholesterol in the bloodstream during use.
TESTOMED C 250 (Testosterone Cypionate) Cycles and Use
TESTOMED C 250 (Testosterone Cypionate) cycles represent one of the most common among anabolic steroid users. Cutting, bulking, mass gaining, and strength gaining periods of training are all possible with TESTOMED C 250 (Testosterone Cypionate).This steroid can also be effectively used (albeit at a lower dosage) for cutting cycles where fat loss is the primary goal.
For the purpose of bulking and/or gaining mass and strength, TESTOMED C 250 (Testosterone Cypionate) is usually employed at a higher dosage (approximately 500mg/week). It is usually utilized at this dosage for a period of 12 – 14 weeks due to its longer ester, and therefore longer half-life. TESTOMED C 250 (Testosterone Cypionate) possesses a half-life of around 10 – 12 days. TESTOMED C 250 (Testosterone Cypionate) is often compared to its almost identical brother, Testosterone Enanthate. Testosterone Enanthate has an elimination half-life of around 7 – 10 days.
TESTOMED C 250 (Testosterone Cypionate) is usually utilized with and stacked with other anabolic steroids that possess very similar characteristics for obvious reasons. It is commonly stacked to compounds such as Deca-Durabolin (Nandrolone Decanoate), which is usually run for the same 10 – 12 week length as Testosterone Cypionate and a ‘kickstarting’ compound such as Dianabol (Methandrostenolone) is usually included from the start of the cycle until it is discontinued at around week 4 or 6.
If TESTOMED C 250 (Testosterone Cypionate) is used in a cutting or fat loss cycle, it can be employed in the manner of a supportive compound only to maintain natural and normal levels of Testosterone hormone in the body while a stronger compound better suited to the fat loss role does the job. This is known as using TESTOMED C 250 (Testosterone Cypionate) at a TRT (Testosterone Replacement Therapy) dosage of around 100mg/week.
Dosages and Administration of TESTOMED C 250 (Testosterone Cypionate)
Medically, TESTOMED C 250 (Testosterone Cypionate) is prescribed at 250mg once every 2 – 4 weeks, which is also dependent on the physician’s protocol, and the patient’s progress in his TRT therapy. If it is used for bodybuilding and performance enhancement, TESTOMED C 250 (Testosterone Cypionate) is normally run at around 300 – 500mg weekly as a beginner dosage range.
Intermediate TESTOMED C 250 (Testosterone Cypionate) dosages are often in the range of 500 – 750mg per week and advanced users are known for running as high as 1,000mg or more per week of Testosterone Cypionate. As TESTOMED C 250 (Testosterone Cypionate) possesses a half-life of around 10 – 12 days, it is recommended that TESTOMED C 250 (Testosterone Cypionate) is administered once per week at an absolute minimum. Ideally, TESTOMED C 250 (Testosterone Cypionate) should be administered two times per week where the dosage is split evenly between injections.
For example, a TESTOMED C 250 (Testosterone Cypionate) dosing of 500mg/week should be administered as 250mg on Monday and 250mg on Thursday every week. Such dosage minimizes peaks and valleys in blood plasma levels, that way it also reduces certain unwanted side effects due to spiking blood plasma levels of the hormone.
