Proviron by Dragon Pharma
What Is Proviron?
Proviron from Dragon Pharma is an oral androgen built on mesterolone, a DHT-derived compound that does not convert to estrogen. Each tablet holds 25 mg of active substance and every pack contains 100 tablets. It is not a heavy anabolic in the way of testosterone or nandrolone; its reputation rests on what it does to the hormone environment around a cycle - freeing up more active testosterone, tightening the look, and keeping androgen tone steady.
Bodybuilders add Proviron when they want a drier, harder and more defined physique during a mass or cutting run. Mesterolone binds to SHBG, which raises the amount of unbound, active testosterone in circulation, and it lowers aromatase activity, so estrogen-driven bloating tends to stay in check. The practical result is better muscle hardness, a cleaner finish at lower body fat, and often a clear lift in libido and training drive.
Because it is far gentler on the liver than 17-alpha-alkylated orals, Proviron is one of the few androgens that fits comfortably into on-cycle support, cruise phases, bridges between cycles, or alongside TRT. Dragon Pharma Proviron 25 mg gives you a reliably dosed tablet for dialing in that effect without turning the run into a guessing game.
Proviron Dosage
Proviron is dosed in tablets, and the reference range most often cited in bodybuilding stays modest because mesterolone is a support androgen rather than a primary mass builder. Common daily totals run from 25 mg to 75 mg, split into two or three doses spread across the day.
| Scenario | Reference dose | Note |
|---|---|---|
| Starting point | 25 mg per day (one tablet) | Assess tolerance and response first |
| Standard on-cycle support | 50 mg per day, split into 25 mg twice | Most commonly cited level |
| Peak hardness window | Up to 75 mg per day in three doses | Advanced use only, kept short |
| Run length | 6-10 weeks, then a break | Fits on-cycle, bridge or cruise use |
Bloodwork Guidance
Timing is flexible because mesterolone acts steadily rather than in sharp peaks; most users prefer one tablet in the morning and one in the afternoon so androgen tone stays even. Bloodwork, especially estradiol and lipids, is the responsible way to confirm the dose suits you, and reference users rarely push past 75 mg per day for long stretches.
Proviron Stacks
Proviron works best on top of compounds that already drive size or conditioning, since its job is to sharpen the androgen environment and the finish. Every partner below is a Dragon Pharma product.
| Stack partner | Role in the stack |
|---|---|
| Cypionat 250 | Testosterone base that benefits from a higher free hormone fraction |
| Enanthate 250 | Long-ester test base for the same free-testosterone effect |
| Deca 300 | Nandrolone block where Proviron supports drive and a drier look |
| Masteron 200 | DHT-class partner for hardness and a cosmetic finish |
| Anavar 10 | Lean mass oral that pairs cleanly with anti-estrogen tone |
| Winstrol 10 | Dry, defined finish in a cut or pre-contest window |
| Arimidex | Stronger estrogen control where the AI load needs to be higher |
Because Proviron itself adds a little aromatase inhibition, keep an eye on total estrogen when it is combined with a dedicated AI. Many references use one or the other as the main estrogen lever rather than stacking both at full strength.
Proviron Side Effects
Mesterolone is considered one of the friendlier androgens, but it is still an androgen, and the effects that matter most are typical of DHT-derived compounds plus the usual lipid shift.
- Androgenic: oily skin, acne, and faster scalp hair loss in men who are already predisposed
- Lipids: a drop in HDL cholesterol is the most common bloodwork change
- Estrogen: near-zero aromatization means low-estrogen sides can appear if it is stacked carelessly with a full-dose AI
- Natural testosterone: HPTA output still shifts while on androgens, so recovery planning matters after long runs
Run bloodwork before and after a cycle, keep the dose inside the reference range, and treat Proviron as a finishing and support tool rather than a base. Used that way it is about as manageable as an oral androgen gets.
What is Proviron?
Proviron is the trade name for mesterolone, an oral DHT-derived androgen made as 25 mg tablets. Dragon Pharma supplies it as a 100-tablet pack used mainly for androgen support rather than mass building.
What does Proviron do in bodybuilding?
Proviron supports a drier, harder physique by binding SHBG and freeing up more active testosterone. It also lowers aromatase activity slightly, which helps keep estrogen-driven bloating and water retention in check during a cycle.
Is Proviron a steroid?
Yes, it is an androgen, but a mild one compared with testosterone or nandrolone. Its anabolic rating is low, which is why it is used as a support and finishing compound instead of a primary mass driver.
How much Proviron should I take per day?
The most commonly cited reference range is 25-75 mg per day, split into two or three doses. Most users settle at 50 mg daily and only advanced protocols push toward 75 mg for short windows.
When should I take Proviron - on cycle, during PCT, or both?
Proviron is mostly an on-cycle and bridge tool: it keeps free testosterone higher while aromatizing compounds are running. Some users also keep it through early recovery, but a true SERM-based PCT remains the standard for restarting natural production.
Does Proviron increase free testosterone?
Indirectly, yes. Mesterolone binds strongly to SHBG, the protein that normally holds testosterone, so less of it gets bound and more stays active. Bloodwork often shows a higher free testosterone fraction while total testosterone stays similar.
Does Proviron help with estrogen and gyno?
Proviron has mild aromatase-inhibiting activity, so it can reduce estrogen conversion and help prevent water bloat and gyno flare-ups in mild cases. For real estrogen problems a dedicated AI or SERM is the stronger tool.
Can Proviron cause erectile dysfunction?
It is more often reported to improve libido, but low-estrogen sides from heavy suppression can include erectile issues and a flat mood. The key is balance: over-stacking Proviron with a full-dose AI can drive estrogen too low and cause exactly those problems.
Does Proviron cause hair loss?
It can accelerate scalp hair loss in men genetically prone to male pattern baldness, since it is DHT-derived and acts on the same pathway. Keeping the dose moderate and monitoring early shedding is the practical approach.
Is Proviron hard on the liver?
Much less than 17-alpha-alkylated orals such as Dianabol or Winstrol. Mesterolone is 1-alpha-methylated, so hepatic strain is lower, but lipids and general bloodwork should still be checked on any oral androgen run.
