Metenolone enanthate​ Descriptions 

Metenolone enanthate, or methenolone enanthate, is a dihydrotestosterone (DHT)-based anabolic steroid. It is an ester derivative of methenolone sold commonly under the brand names Primobolan (tablet form) or Primobolan Depot (injectable). When it interacts with the aromatase enzyme it does not form any estrogens.[medical citation needed] It is used by people who are very susceptible to estrogenic side effects, having lower estrogenic properties than nandrolone.[medical citation needed] Methenolone, in form of enanthate and acetate, is available as an injection or as an oral formulation. The injection is regarded as having a higher bioavailability. It is an enanthate ester which is quite long-acting. Because it by-passes hepatic breakdown on the first pass, it also has a higher survival rate. The tablets are in a short-lived acetate form. Methenolone is not 17-alpha-alkylated, but 1-methylated for oral bioavailability. This reduces the stress on the liver, but also the availability. In doses of 200 mg per week or less (intramuscular) blood pressure is rarely altered.[medical citation needed]; Methenolone can be suppressive of the hypothalamic-pituitary-gonadal axis.


Way TO Use Metenolone enanthate​

Currently, there are two forms of primo on the market.

  1. The first, and most popular, version is enanthate, which is an injectable form. It comes in an oil based solution in ampules or multi-use vials.
  2. The second version is acetate, which is an oral 1-methylated version. Both esters have benefits and drawbacks.

Metenolone enanthate​ Dose 

The problem with primobolan is the price vs. results value. You need to use fairly high doses to get good results.

1. For men, injectable dosages should be 600-800mgs per week or higher, and oral dosages should be around 75-100mgs per day.

2. For women, I suggest using only oral primobolan. Around 10mgs per day seems to be a good amount to start with. You should play with the dosage but never go over 20mgs per day.


Half-life of Primobolan

For the injectable version, Primobolan Enanthate, the half-life is around 10 days. T

he oral version has conflicting evidence about half-life.

There are some studies that claim Primobolan Acetate has a 4 hour half-life, while others claim 6 hours. Therefore, to be safe, oral primo has a 4 to 6 hour half-life.
