What is PROVIMED 25 (Mesterolone)?
PROVIMED 25 is Proviron, the support compound that makes the rest of a cycle work harder rather than adding anything of its own.
Also sold as Proviron, Provironum or mesterolone.
Mesterolone is a DHT derivative that cannot aromatise and, unusually for an oral, is not 17-alpha-alkylated. It binds strongly to SHBG, the protein that holds testosterone in an inactive state, which frees up more of whatever testosterone is already in your system. That, rather than any anabolic effect of its own, is what it actually does. Read our full Proviron overview.
PROVIMED 25 benefits
- Frees up testosterone already in your system by binding SHBG
- Not 17-alpha-alkylated, so the liver is not what limits it
- Cannot aromatise, and mildly reduces conversion from other compounds
- Commonly used for libido and a harder look rather than for size
- Can be run for longer than an alkylated oral, because the usual ceiling does not apply
- 25mg tablets suit the common 25 to 50mg range without splitting
PROVIMED 25 dosage
- Standard
- 25 to 50mg per day
- Higher end
- 75 to 100mg per day
- Frequency
- Once or twice daily
- Half-life
- About 12 hours
- Cycle length
- Can run the length of the cycle, the liver is not the limit
Most people sit at 25 to 50mg a day, taken alongside a cycle rather than on its own. Because it is not alkylated, the four to eight week ceiling that applies to the other orals here does not apply to this one.
Running it alone achieves very little. Mesterolone frees up testosterone that is already there. If there is not much there, there is not much to free.

Who is PROVIMED 25 for?
People already running a cycle who want more out of the testosterone in it, a firmer look, and libido maintained through a run built on 19-nors.
It is the wrong purchase for anyone expecting to gain size from it. Astera Labs sells 50mg tablets, which suit the higher end of the range.
How to use PROVIMED 25
Swallow with water, once or twice daily. It can be taken alongside food. No cycling limit is imposed by the liver, so it is commonly run for the length of whatever it is supporting.
Frequently asked questions
Will mesterolone build muscle?
No, and this is the most common misunderstanding about it. Mesterolone is a very weak anabolic and running it alone produces almost nothing in the way of size.
What it does is bind SHBG, which raises the free portion of the testosterone already in your system. That makes the rest of a cycle work harder. On its own there is very little for it to free up.
Is it liver toxic?
No, and it is one of the few orals here where that is true. Mesterolone is 1-methylated rather than 17-alpha-alkylated, so it survives digestion without the modification that stresses the liver.
That is why it can be run for longer than the four to eight weeks that limit the alkylated orals. It is not a free pass on everything else, but the liver is genuinely not the constraint here.
Can it replace an aromatase inhibitor?
Not reliably. Mesterolone does compete with the aromatase enzyme and mildly reduces conversion, so it takes some edge off the estrogen load.
It is not strong enough to control estrogen on a heavy aromatising cycle. Treat it as a small help alongside a proper aromatase inhibitor, not a substitute for one.
Does it suppress natural testosterone?
At higher doses, yes, which contradicts the common claim that it does not. 25mg a day has little effect for most people, but 100mg a day is suppressive.
It is not the compound most likely to shut you down, but it is not exempt either. If you are running it alone at a high dose, expect some suppression.
Why do people run it on cycle?
Two reasons. The SHBG binding raises free testosterone, so the rest of the cycle works harder for the same dose. And it firms up the look, since it is a DHT derivative with no water attached to it.
Libido is the third reason, particularly on cycles built around 19-nors, which are notorious for blunting it.
