What is the Difference Between Test E and Test C

The main difference between Test E and test C is that the half-life of Test E is 10.5 days whereas the half-life of Test C is 12 days. Furthermore, Test E is a 7-carbon compound while Test C is an 8-carbon compound.

Test E (Testosterone Enanthate) and test C (Testosterone Cypionate) are two types of esterified testosterone variants with increased half-life. They are important in bodybuilding for increasing the muscle mass but, these variants do not show any significant difference in the form of testosterone boosters.

What is Test E

Test E or Testosterone Enanthate is a more popular androgen commonly sold under many brand names including Delatestryl, Testro, Testoviron, Testostroval, etc. It is used as both androgenic and anabolic steroid for the treatment of low testosterone levels responsible for weight gain, loss of muscle mass, depression, erectile dysfunction, and gyno-based side effects such as man boobs. Therefore, Test E is important in both muscle building and increasing male sex characteristics. Today, many bodybuilders use it for speeding up recovery and burning fat as well.

Furthermore, the half-life of Test E is about 7-10 days, allowing injection once or twice per week. Therefore, it is more suitable for medical and bodybuilding purposes especially, for those who are not comfortable with engaging in frequent injections.

What is Test C

Test C or Testosterone Cypionate is another variant of esterified testosterone with a half-life of 12 days. It is an equivalent of Test E though it has a different chemical structure to the Test E. Also, the increased half-life further reduces the frequency of injection. However, this product has a universal origin. Moreover, it can also be used to treat hypogonadism resulted in low testosterone levels.

Moreover, for beginners, the standard dosage of Test C is 400 to 500 mg for a 12-week cycle. The injections have to be taken for three times per week. However, those who had Test C before, an increased dosage of 600 or 700 mg for a 12-week cycle can be injected. Additionally, when stacking with other anabolic compounds including Winstrol and Human Growth Hormone (HGH), one can take a less dosage of Test C, which is 200 mg.

Similarities Between Test E and Test C

• Test E and Test C are two types of esterified testosterone variants.
• The main purpose of testosterone esterification is to maximize medical and non-medical use.
• Therefore, both variants are more practical and usable.
• They have increased half-life.
• They are androgens with an almost similar effect as testosterone boosters.
• Both are important in medicine and bodybuilding to increase low testosterone levels.
• They can be administrated through injections.
• Both are popular due to the increased half-life and prolonged window of release that enables more convenient injection and administration procedures to be carried out.

Difference Between Test E and Test C

Definition

Test E or Testosterone Enanthate refers to a white or whitish crystalline ester C₂₆H₄₀O₃ of testosterone that is used especially in the treatment of eunuchism, eunuchoidism, androgen deficiency after castration, symptoms of andropause, and oligospermia while Test C or Testosterone Cypionate refers to the oil-soluble 17 (beta)-cyclopentylpropionate ester of the androgenic hormone testosterone used mainly in the treatment of low testosterone levels in men. Thus, this explains the main difference between Test E and Test C.

Origin

Also, another difference between Test E and Test C is that test E has a universal origin while Test C is an American product.

Brand Names

Some brand names of Test E are Delatestryl, Testro, Testoviron, Testostroval, Andro LA, Andropository, Depandro, Durathate, Everone, etc. while the brand names of Test C are Andro Cyp, Andronaq LA, Andronate, Dep Andro, Dep Test, Deposteron, Depostomead, Depotest, Depo-Testosterone, etc. 

Half-Life

Half-life is the main difference between Test E and Test C. The half-life of Test E is 10.5 days while the half-life of Test C is 12 days.

Standard Dosage

The standard dosage of Test E is 100 to 600 mg per week for 10 to 12 weeks while the standard dosage of test C is 400 to 500 mg per week for 12 weeks.

Frequency of Injection

Moreover, Test E has to be injected more frequently than Test C.

Structure

Furthermore, Test E is a 7-carbon ester while Test C is an 8-carbon ester. Hence, this is also a difference between Test E and Test C.

Molecular Weight

Test E has a low molecular weight while test C has a comparatively high molecular weight.

Amount of Testosterone per Gram

In addition, Test E has a higher amount of testosterone per gram while Test C has comparatively a low amount of testosterone per gram.

Popularity

Popularity is also a difference between Test E and Test C. Test E is more popular while Test C is comparatively less popular.

Side Effects

The irritated injection sites is an example of a side effect of Test E while bloating is an example of a side effect of Test C.

Conclusion

Test E or Testosterone Enanthate is a type of esterified testosterone variant with a half-life of 10.5 days. It is a 7-carbon ester with a universal origin. On the other hand, Test C is a type of esterified testosterone variant with a half-life of 12 days. Also, it is an 8-carbon ester with an American origin. However, due to the less prolong half-life, Test E has to be injected more frequently than Test C. Therefore, the main difference between Test E and Test C is how long the user needs to run each compound for maximum effect, as well as the injection frequency based on the ester.
