Metenolone acetate, Oral primo

Metenolone acetate, or methenolone acetate, sold under the brand names Primobolan and Nibal, is an androgen and anabolic steroid (AAS) medication which is used mainly in the treatment of anemia due to bone marrow failure.[1][2][3][4][5][6] It is taken by mouth.[5] Although it was widely used in the past, the drug has mostly been discontinued and hence is now mostly no longer available.[4][5][2] A related drug, metenolone enanthate, is given by injection into muscle.[5]

Side effects of metenolone acetate include symptoms of masculinization like acne, increased hair growth, voice changes, and increased sexual desire.[5] The drug is a synthetic androgen and anabolic steroid and hence is an agonist of the androgen receptor (AR), the biological target of androgens like testosterone and dihydrotestosterone (DHT).[5][7] It has moderate anabolic effects and weak androgenic effects, as well as no estrogenic effects or risk of liver damage.[5][7] Metenolone enanthate is a metenolone ester and a prodrug of metenolone in the body.[5]

Metenolone acetate was introduced for medical use in 1961.[8][5] In addition to its medical use, metenolone acetate is used to improve physique and performance.[5] The drug is a controlled substance in many countries and so non-medical use is generally illicit.[5] It remains marketed for medical use only in a few countries, such as Japan and Moldova.[4][5]

Silntrunin is on a distinguished road
Id imagine the oral is a lot better way to go with this compound. Years ago i couldnt find any primo e raws so i grabbed some acetate thinking it was equivalent to test e/ test p and converted it to injectable. Man was I wrong. That was some of the worst pip ive ever experienced in my life. Lol
Id highly recommend sticking to the oral version if your gonna use it.
