Primobolan
Methenolone enanthate at 100 and 200 mg/ml, with four independent reports behind it.
What Primobolan is
Primobolan is methenolone enanthate, an injectable with an unusually favourable ratio of effect to side effect. It aromatises minimally and carries a low androgenic load, which is the whole basis of its reputation and the reason it is one of the most counterfeited compounds in circulation.

The detail
Its long half-life of roughly 10 to 14 days is much longer than the enanthate ester alone would suggest, and considerably longer than testosterone enanthate at around 4.5 days. Methenolone is a different parent hormone, so the ester name alone does not predict the curve. Because genuine Primobolan is expensive to produce, it attracts substitution more than almost any other compound, which is why finished product testing on a sealed vial matters more here than elsewhere.

Common questions
Where can I buy real Primobolan?
The question to ask of any seller is whether they publish finished product testing on a sealed vial, not just a raw material certificate. Both Primobolan preparations here carry finished product assays: 212.09 mg/ml against a 200 mg/ml label, and 98.48 and 107.22 mg/ml against a 100 mg/ml label, plus raw material confirmed at 99% purity.
Why is Primobolan counterfeited so often?
Because genuine methenolone is expensive to produce relative to compounds it can be substituted with. That is precisely why a finished product assay on a sealed vial is worth more here than a raw material certificate: it measures what actually ended up in the vial.
Is Primobolan the same as methenolone?
Yes. Methenolone enanthate is the chemical name and Primobolan the brand.
Does this page give dosing information for Primobolan?
No. This is a reference resource covering the compound, its concentrations and its verification. It does not provide dosing protocols or administration schedules.
