+ 72 Proviron...Should you use it?


Resulting from numerous posts asking about proviron's uses and general questions, i have created a short fact sheet below, which not only encompasses common knowledge, it also identifies the un-common rules associated with proviron.

Proviron roster:

1) What is Proviron?
2) Proviron's uses x4
3) Benefits of proviron use on cycle
4) Proviron and Deca
5) Proviron dosages
6) Conclusion
7) My experiences

Proviron is a DHT derivative used by AAS bodybuilders to reduce the aromatisation of testosterone and its derivatives. Thus, effectively there will be more free testosterone, which the human body uses to build muscle. Additionally it has been reported through AAS users to help amplify the effect of a cycle (since it increases the amount of free testosterone).

However, in order to substantiate my aforementioned point, proviron does help to release free testosterone, thus increasing overall free testosterone levels useful for bodybuilding. In addition, proviron also helps keep estrogen levels under control in the male body (which means it can be used to compliment your AI (whether it be asin, adex, caber, letro)) - but this compound cannot be used for PCT.

Bodybuilders use proviron for four main reasons outlined below:

1) As a result of proviron's atomic structure it is incapable of forming estrogen. Therefore, due to the increased strength (in comparison to testosterone) in its binding ability to 'latch-on' to the estrogen binding enzymes, it prevents estrogen build-up.

2) As previously mentioned, proviron increases the amount of free testosterone in the male human body. This is a very important point to consider, since approximately ~98% of testosterone is bound to the sex-hormone-binding-globulin (SHBG), thus, since it is bound to the SHBG it is not free testosterone any more and therefore cannot be used to build muscle.

3) As a DHT derivative, proviron contributes towards a feeling of 'well being' (commonly referred to as anabolic well-being) in males, thus it has been used to treat depression in men in the past. Additionally, bodybuilders use it to 'dry up' for competitions, however Masteron is the preferred choice and considered as a better option (proviron has been named as an oral masteron - this topic is debateable). The increase in hardness comes from a reduction in free estrogen levels, thus decreasing water retention.

4) Proviron is frequently used with compounds such as deca - as it adds an androgenic component to the cycle. Thus preventing a loss in male libido and impotence and helps a males sex-drive upto a certain point. However, it makes much more sense to use testosterone (and compounds like prop, tne, suspension) which are very useful since it's a natural sexual hormone.

A dosage of 25mg ED is considered to be an effective dosage for proviron.

To finalise supplementation of 25mg proviron a day during 19-nor-progesterone cycle will help to aid and (i use this word with caution) amplify the effects of that particular cycle, since there is in increase in free testosterone, which is what the human body utilises to build muscle.

I thank all you guys commenting on this proviron topic - and you may be asking yourself, why did i chose to write this...karma? Well...it would be good in encouraging me to continue to write posts and learn more to share my knowledge base, but also to gain opinions.

We have the simple facts (as above), but personal experiences are where it's at.

I came across proviron 2 years ago, where a friend had no clue what to do with it let alone what it was for, so he kindly gave me his proviron free of charge - and, i suppose, as a thank you, i decided to write this post (as above), so that if he were ever in a situation where he once again had proviron, he would know when, how and at what dosages to use it at.

So i proceeded with a little self experiment (not particularly scientifically controlled), i chose to do two AAS cycles, very simple ones, however, one had proviron in, and the other didn't.

The cycles are as followes:

Cycle #1 (Without proviron)
Week 1-12 = Test E/500mg per week/2 pins per week of 250mg
Week 3-14 = Aromisin/12.5mg EOD
PCT 15 days after last Test E injection.
Clomid 100/100/50/50
Nolva 40/40/20/20

Cycle #2 (With proviron)
Week 1-12 = Test E/500mg per week/2 pins per week of 250mg
Week 1-12 = Proviron/25mg ED
Week 3-14 = Aromisin/12.5mg EOD
PCT 15 days after last Test E injection.
Clomid 100/100/50/50
Nolva 40/40/20/20

The controlled factors are as followes:

+) Diet was logged throughout Cycle #1 and mirrored into Cycle #2 - same meal sizes, portions, macro-nutrient breakdowns and mealtimes.
+) Training was logged throughout Cycle #1 and mirrored into Cycle #2 (however, an overall increase of ~5% resulting from the first cycle was carried forward).
+) Training time was consistent, same with intensity - I had the same job, so this control was relatively easy to adhere towards.
+) BF% monitored constantly throughout both cycles - BF% remained the same, with a +/- 1% when on cycle due to a tiny bit of bloat


I too, like GS took my asin in the morning with grapefruit juice and peanut butter, and after a week i found myself to be extremely drowsy and de-motivated in comparison to my 'normal' self. So, i did some reading, and found that free estrogen levels peak towards the end of the night, thus, i began takin the asin pre-bed.

Now, my findings as far as the proviron goes - well, libido wise i was flying high on Cycle #1, but with the inclusion of proviron in Cycle #2 made me want to penetrate anything and everything! In my opinion, the dosage i took was conservative, and although it's is hard to quantify, my 'hornyness' rose ~7-10%. Now we conclude...


My gains post PCT with Cycle #1 were 11.5 lbs, and in Cycle #2 were 11lbs.
Now, this has got me thinking. There are many factors which could have played part in here. In my opinion, post Cycles #1 and #2 revealed good gains, but the gains in Cycle #2 dropped slightly - this could be to do with my body being increasingly responsive towards external test sources among many other factors.

Although my conclusion is brief, i do believe proviron is an important factor in ones cycle, simply because the hornyness (feeling of anabolic well-being) was greatly appreciated by myself, through increases in free testosterone, but also in aggression and motivation in the gym

Thanks for reading,

A drug used in children of testosterone with mesterol content. It is a medicine to help you easily from body shaping daa workouts and to give you energy to do more exercise.

No—it is not 17-alkylated and poses no real threat to your liver!! But I’m my time, doing 3 cycles WITH proviron, I can say that it DOES make your dick work like a Greek God—maybe not as much as mast-prop, but proviron doesn’t mess with my hair—when I was on mast—prop, I looked my best that I ever had from the neck down…but every time I took a shower, I was pulling out CLUMPS of my hair. It almost turned me off of gear altogether, but I got on dutasteride from my doctor and started taking rogaine and I finally got pretty much ALL of my hair back—I also had just gone through a bad breakup with a boyfriend of mine, so the Dr didn’t know whether or not it was caused by stress, an autoimmune response, or if it was the mast-prop. So we just hit it with everything. around 6 months later after seeing results from dutasteride, I decided to go on a very HEAVY testosterone cycle (400mg x 2 a week) with proviron, tren enanthate, and caber. Worked like a charm!!

Maybe a stupid question, but would there be any benefit to taking HGH and proviron only? Has anyone tried proviron on its own? Like I said, maybe a stupid question, but trying to learn. From the initial post it seems like it could have some benefits in its own right. Just curious. Thanks guys.

I am not an expert but this is what I have found. It is a good read. I would suggest it, if interested in this compound.

"Due to minimal testosterone suppression, it is possible to use this anabolic steroid without exogenous testosterone or at least with a very minimal amount....However, most will be using other anabolic steroids that are highly suppressive to natural testosterone production along with Proviron making the use of exogenous testosterone imperative..."

It is a crapshoot using when not supplementing with exogenous test. Members on here have shown with bloodwork that it suppressed them. I would just stick to using while on cycle to be safe.

Walkertexasranger's picture

Right on. Thank you guys. Janus, great link. Sometimes I forget to cross reference on other sites. Makwa, thank you, I will definitely not be taking that risk. Much appreciation.

Not unless you are on TRT. Provi will eventually shut you down.

Twenty five years ago, proviron was my anti aomatase of choice because letrozol was very expensive and only available in pharmacy. I took a lot of testosterone and I never had big issues with E2 except water retention. My daily dosage was up to 100 mg of mesterolone

Failuretobreathe33's picture

I dontvrun it as a PCT but I have read from numerous different threads that it's great for PCT short term. I run it first 3 or 4 weeks on the start of my cruise.

Shaman's picture

Safe yes, beneficial no as aromasin does the job

Vincent Vega619's picture

I think I would stick with 50mg tab of proviron split 2x a day and if you feel estro sides coming on ,get your bloods ran. That is only true way to tell. Everyone receives sides at different levels etc. Etc. So you have to find your sweet spit and only way to do that is get your bloods ran as you tweak your cycle and once you know optimum levels in accordance to dosing you will good to go

Big Tone36's picture

I wouldn't even take the aromasin unless sides estro sides appear. 50mg proviron ed (split 12h as suggested below) might be all you need to keep estro in check with just enough in the blood stream to help in the muscle building process. Anadrol is weird we dont fully understand, it doesn't aromatase into estro , but estro related sides like some report tremendous amount of water gain. I don't ever get this , i actually just appear fuller, more vascular and big strength gains. No crazy water gain. Also, i also stress taking your liver aids (nac, milk thisle, tudca) and no more than 100mg total with all oral compounds combine. 50mg anadrol 50mg proviron is a responsible dose.

Shaman's picture

The ratio andro / E2 ,is primordial even among naty . You are right blood work is important as it gives accurate informations

Big Tone36's picture

Exactly. AI are good if you are dieting and trying cut water and good if your running tremendous amounts of gear. Everyone is different, i dont suffer from estro sides up to 1000mg, some people will suffer so you have to know your body. But for growing you just want to blunt estrogen and keep it in good range because it will aid in muscle building process. I like proviron for this reason and for lowering SHBG allowing test to be in more free state making that 500mg dose work great. Anadrol also has the capability of lowering SHBG like most DHT derived compounds.

Shaman's picture

All the aas that do not aromatise, can help to lower shbg mostly dht derivatives, your are right

Great Post, everything I needed to know, definitely going to add it into my cycles from now on and see how it goes!!!

JohnnyTest69's picture

Have ran from 50-100 mg per day this stuff really hardens you up sexually and physique wise lol nothing boosted my libido and alpha feeling like some proviron. Ripped out the hair but was a nice run lol the higher end of dosage dried me out a little too much 50 mg ED was sweet spot for me. Brought out the veins as well just not much strength. Great post!


FYEA all day every day ...... add it on any and all runs a requirement IMO esp on test or aromatizers its a lil pricey thou actually

realchico's picture

i started incorporating Proviron in my TRT at just 50 mg per day and my libido increased. I feel great on proviron.

MONK's picture

Still remains one of the most over looked and under rated aas meds out there imo. New users far too quick and tempted by the multitude of candy flavours on the sources shelves, anavar, dbol, tbol etc sack them all off and learn to grow and get the absolute most possible out off the absolute least compounds.

Fantastic write up and a post I’ve referenced many of times over the years.

lxxRICHxxl's picture

Well written. Good read. I am currently on my second cycle and I'm taking Test and Anavar. I'm researching adding Proviron for the well being and sexual boost.

tonymontanaa's picture

Thanks for information, it is useful for people like me who just starting.

gapi2911's picture

Good copy. I still think that Proviron on MY blast is overrated. I can tell from my own experience that I gather over the years using only real pharma grade from the pharmacy here in my country (EU) on a script. Yes I have used Turkish bought in Turkish pharmacy where is A LOT cheaper which is mostly seen on a quality of the packaging but still good. I really feel that it has a litlle effect on cycle and is rather useful in between blasts. I never used large doses, only 25-50mg but for its price, I rather use good pharma HGH all year round. As for effect on my bloods, it has a litlle effect, mostly on my libido but still for this I rather use Cialis. There are a lot better and cheaper meds for SHGB.
Still for beginners that have enough money to spend for a REAL good quality cycle and have covered all the basics and have a good PC.
That is my piece.

Great day all


libido and e2 are my reasons it works for me like that

Bjmoney85's picture

I know this is old as shit but could you tell me if they still make this brand I’m looking into som liv support soon!

Danavar's picture

i wonder if you got less gains on cycle 2 because your e2 was lower than optimal due to proviron binding to aromatase?
