Primobolan (Methenolone) is an anabolic steroid, which originates from dihydrotestosterone. It has weak androgenic and moderate anabolic properties. This hormone is available in the form of tablets (Oral Primobolan), and injectable form (:primobolan:).
Injectable version of this substance (Primobolan Depot) is an Enanthate ester of Methenolone, which has prolonged action (about two weeks). It is regarded as one of the safest steroid. In medical practice it was successfully applied in treatment of underweight children, osteoporosis and sarcopenia. The major inconvenience is that its injection is rather painful.
A tablet version of Primobolan (Methenolone acetate) has shorter period of action (approximately five hours). Unlike other tablet steroids, Oral Primobolan has low liver toxicity. Nevertheless most bodybuilders prefer injectable version of Methenolone due to lower price and higher bioavailability of the hormone.

Transformation into estrogens – no
Liver toxicity – low
Available forms – tabs, injections
Half-life – 5-20 hours (tablets); 4-7 days (for injections)
Doping test – detectable during 100 days (tablets), or 6 months (injections)
Effekter
Comparing to :decadurabolin: the anabolic effect of Methenolone is rather mild. Therefore most bodybuilders use it during cutting cycles, when the main goal is not to gain muscle mass but to preserve it.
Bieffekter
As Primobolan is not an aromatizable steroid, there is no risk of estrogen-related side-effects (gynecomastia and water retention).
Methenolone may decrease the level of natural testosterone synthesis to a little degree. However this effect is much weaker than in Testosterone and Nandrolone. For instance, the cycle of Oral Primobolan at the dose of 40mg/day can suppress the levels of endogenous testosterone by 50%.
In case of long cycles or high doses, the usage of gonadotropin is necessary (in order to avoid testicular atrophy). Methenolone does not affect the level of bad cholesterol (LDL) and does not increase blood pressure.
Due to the low androgenic activity the cases of baldness are very rare. Despite high safety rating the following side-effects may occur: aggression, excitability, insomnia, increase of liver enzymes etc.
Dosering och användning
Usually athletes take Primobolan for cutting cycles or to preserve muscles. Owing to mild action the length of a cycle should last up to eight weeks. However longer period may increase the risks of adverse effects.
The common doses of Oral Primolaban are 50-100mg/day. In 2-3 days after the end of a cycle you should start PCT. The usual dosage of injectable Primobolan (Depot) is 400mg/once a week. Post Cycle Therapy should begin in 3 weeks since last injection.
Consult your doctor before taking Primobolan, make sure you don’t have contraindications.
Primobolan Combinations
Because of mild anabolic effect, bodybuilders often stack it with other steroids. For muscle gains it is usually combined with :nandrolone: (probably the safest cycle), :testosterone-c:, :anadrol: or :methandrostenolone:. For cutting cycles it is combined with :winstrol:.
Do not introduce more than one steroid into your combination. Take both steroids at half-doses. This method will decrease the risks of side-effects and enhance efficiency of your cycle.
