Product Overview
Dragon Pharma Proviron is mesterolone in 25 mg tablets, one hundred to a box. The compound is a dihydrotestosterone derivative with a strong androgenic character and a weak anabolic one, which sets the tone for everything that follows: this is not a builder of mass, it is an androgen used to shape the quality of a cycle.
Two structural facts separate it from the rest of the oral shelf. First, mesterolone is not alkylated at the 17-alpha position, and it is one of the very few orally active steroids for which that is true - which is why its hepatic risk is classed as low in the reference material instead of the usual warning. Second, it binds sex hormone binding globulin with high affinity. That binding is the reason it is used alongside other compounds: by occupying the protein that would otherwise hold testosterone, it leaves a larger fraction of testosterone free and biologically available.
It also does not aromatise, so neither water retention nor gynecomastia arises from this molecule itself. Proviron is therefore positioned as a partner compound - commonly in a stack with an aromatising base such as Cypionat 250 or Deca 300, and often discussed next to Masteron 100 because both are DHT-derived and neither converts.
Dosage Protocol
Proviron is oral and the active life is around half a day, so the daily total is usually divided. In replacement therapy the reference schedule is 25 mg two or three times a day; sports use runs lighter and follows the length of the main cycle rather than a fixed number of weeks.
| Beginner | 25 mg a day, continued for the length of the main cycle |
| Intermediate | 50 mg a day, often divided into two intakes |
| Advanced | 50-100 mg a day; the upper figure comes from vendor practice and no reviewed source confirms it |
| Female | Not recommended; the androgenic load carries a high virilisation risk |
| Administration | Oral, divided through the day because the half-life is about half a day |
Because the tablet is 25 mg, the entry dose is a single tablet a day, which keeps the arithmetic simple and makes the 100 mg figure four tablets daily. Nothing in the reference material suggests that going above that adds anything other than androgenic side effects, and combining Proviron with a second DHT-derived oral does not create a stronger effect - it only adds to the androgenic load.
Suggested Protocols
Proviron works as a supporting agent. It is added to a cycle that already has a base, and it is removed when that cycle ends.
What to Expect
- Androgenic tone. By week one or two most users report higher libido and a firmer, denser appearance rather than a change on the scale.
- Free testosterone. Binding of SHBG releases testosterone that was previously held in reserve, so the change is in the free fraction rather than in total production.
- No water, no gyno. The molecule does not aromatise, so neither of those estrogen-driven effects belongs to it.
- The androgenic flip side. Acne, hair shedding and voice change are possible, and they are the practical limit on how long a high dose can be sustained.
- Modest scale movement. This is an androgenic compound with a weak anabolic signal, so it adds quality rather than size.
- Limitation: not a base. Proviron does not replace a testosterone ester as the foundation of a cycle, and it does not act as an aromatase inhibitor or a SERM.
- Limitation: no verified upper dose. The 100 mg figure circulates in vendor material, but no reviewed source confirms where the ceiling actually sits.
Side Effects and Management
The profile here is androgenic rather than hepatic or estrogenic, and the items below are the ones that actually shape how long a course can run.
Chest symptoms on a Proviron-supported cycle never come from mesterolone itself. They belong to the aromatising compounds in that cycle, and they are handled on those terms: a SERM such as Nolvadex where tissue is already reacting, or Arimidex where estradiol is measurably high.
Post-Cycle Therapy
This section carries a correction rather than a schedule. Mesterolone is not a recovery drug, and using it in place of a SERM leaves the suppressed axis exactly where it was.
