What is Methenolone Enanthate 200 (Astera Labs)?
Astera Labs methenolone enanthate at 200mg/ml, in a 10ml vial. Primobolan at double the usual strength, for the doses this compound actually needs.
Also sold as Primobolan, Primobolan Depot or metenolone enanthate.
Methenolone is a DHT derivative that cannot aromatise, and it is genuinely mild. That mildness is the whole proposition: very few side effects, no water, no estrogen, and a slow steady effect that holds lean tissue through a deficit. It is also weak, which is why the doses are high.
Methenolone Enanthate 200 benefits
- One of the mildest injectables available, with very few side effects reported
- Cannot aromatise, so no water retention and no estrogen from it
- Holds lean tissue through a calorie deficit, which is its main use
- Mild enough that it is one of the few compounds women run at all
- 200mg/ml, so a 600mg week is 3ml rather than 6ml at the standard strength
Methenolone Enanthate 200 dosage
- Standard
- 400 to 600mg per week, which is 2 to 3ml
- Higher end
- 600 to 800mg per week
- Run alongside
- Testosterone as the base
- Frequency
- Twice weekly
- Half-life
- About 10 days
- Cycle length
- 12 to 16 weeks
At 200mg/ml a 600mg week is 3ml rather than the 6ml it would be at the standard strength. On a compound that needs high doses for twelve to sixteen weeks, that is the difference between manageable and not.
Under-dosing is the usual mistake. Methenolone is genuinely weak, and 200mg a week will do very little.

Who is Methenolone Enanthate 200 for?
Men running methenolone at the doses it genuinely needs, where the volume at 100mg/ml becomes the limiting factor rather than anything else.
It is the wrong choice for small doses. Women running 50 to 100mg a week, or anyone dosing in fractions, are better served by the 100mg/ml version, where the same amount is easier to measure accurately.
How to use Methenolone Enanthate 200
