British Dragon Primobol is methenolone enanthate at 100 mg per ml in a 10 ml multi-dose vial. It is a DHT-derived injectable with a modest anabolic and weak androgenic profile, which is why it is described in the sources as a clean, slow builder rather than a mass drug. Because it does not aromatise, there is no water retention and no gynaecomastia from the compound itself, and it is commonly run beside a testosterone ester such as Testabol so that the androgen base is covered.
The enanthate chain gives methenolone one of the longest release windows in its group, roughly ten and a half days after an intramuscular shot, so injections land twice a week and the level stays even. The molecule itself binds the androgen receptor without being converted to oestrogen, and the project material records no described hepatic risk for this compound, which separates it from the 17-alpha-alkylated orals. The price is that the effect is not dramatic: users report a gradual, dry gain in lean tissue that is easier to hold afterwards. It is usually compared with the other mild cutting options, Anavar and Masteron, and it is the middle ground between them in strength of effect.
Weekly community ranges start around 200 to 300 mg for a first course and rise to about 600 mg for experienced users, always split over two injections because of the ester. Courses run eight to twelve weeks. Methenolone is often the mild component of a stack rather than the whole plan, so a dry oral such as Winstrol may be added for a short block. It does not aromatise, so an aromatase inhibitor such as Arimidex is not part of the default plan. Because it is an androgen it still suppresses natural testosterone, so recovery uses Nolvadex 20 mg daily for four weeks or Clomid as the alternative.

Before you ask
Primobol is methenolone enanthate at 100 mg per ml in a 10 ml multi-dose vial. It is a DHT-derived injectable with a moderate anabolic and weak androgenic profile, which is why the sources describe it as a mild compound used for clean, slow gains. It does not aromatise, so it does not add water. The vial holds one concentration and one pack size, so there are no dose options to choose between.
The enanthate ester is long, with a half-life of roughly ten and a half days in the project material, so two injections a week hold a steady level. That is far less frequent than the short-ester alternatives. Weekly totals are then split across those two shots rather than given in one, which keeps the release curve flatter and the peaks lower.
No. Methenolone is not aromatised to oestrogen, so the compound itself does not produce a water load or breast tissue, and an aromatase inhibitor is not part of its default plan. If bloating appears during a run, the cause is another aromatising compound in the same stack, such as a testosterone ester, and that is where the oestrogen control belongs.
The profile is mild compared with stronger androgens, but it is not empty. Reported effects include acne, oily skin and hair loss in those predisposed, androgen-related mood change, and suppression of natural testosterone production. Because it is an androgen, women who use it risk virilisation, and the sources list the female use case as one that needs careful supervision rather than a routine option. Persistent symptoms warrant medical advice.
Yes. Methenolone is an androgen and suppresses the body's own testosterone, so a course finishes with a SERM protocol: tamoxifen 20 mg daily for four weeks, with clomiphene as the alternative. Because the ester is long, the start of recovery waits until it has cleared, which takes longer than a propionate would. Blood work confirms the axis has restarted.
