Methenolone Enanthate

Methenolone enanthate also known as primobolan depot is an anabolic androgenic steroid derived from dihydrotestosterone, which is most commonly found as an injected steroid. Its bond to a carboxylic acid or enanthate ester helps the enanthate ester release slower into the bloodstream lasting a longer period of time, approximately 2 to 3 weeks depending on the individuals metabolism and the initial hormone levels in the body. To maintain balanced levels of methenolone in the body it is important to reapply the steroid in the body every 2 weeks, unlike athletes who require 1 to 2 applications weekly due to their specific needs.

Chemical Characteristics

methenolone enanthate is a modified form of the male hormone dihydrotestosterone. The ester enantonic acid is bonded to a 17-beta hydroxyl group. This modified form is not as polar as free hormones generating a slower absorption into the bloodstream.

Once in the bloodstream the enanthate ester is released from the methenolone making it free and active. This type of esterified steroid was designed to prolong the effect of the hormone in the body requiring less application in comparison to those steroids that are not esterified. The half life of methenolone enanthate is approximately 8 days.

Side Effects

methenolone does not have the capacity to aromatize in the body, meaning it does not metabolize into estrogen. Like all androgenic anabolic steroids methenolone enanthate suppresses the function of the hypothalamus axis-pituitary-gonadal decreasing the production of endogenous testosterone, with prolonged use the individual could hypogonadism. The problems caused by the androgenicity are very low making this a very safe steroid to use.

When high doses are administered the side effects commonly found are acne and oily skin. An important factor to take into consideration is the difference between methenolone enanthate and methenolone acetate. Methenolone enanthate has a longer half life which requiring close monitoring when women use it. If a virilization effect is noticed it will not subside until the methylone is 100% of out the bloodstream. Although methenolone enanthate is injected intramuscularly it does not have negative effects on the liver making this a safe substance to use.

Raw Material

Methenolone is a fine white powder, easy to compress, stable in normal environmental conditions and has a very low melting point in comparison to other substances.

Finished Product

Methenolone is an oil base, generally a light yellow, transparent colour. In normal concentrations this substance does not crystalize. Its viscosity in comparison to its viscosity is not high. 100mg/ml and 275 mg/ml are commonly used with 20G and 21G needles.
