Primobolan (Metenolone Enanthate)

If there’s one steroid that can be considered as close to perfect as can be, it’d be Primobolan. It not only has the very best “risk to benefit” ratio of any steroid, it’s also the safest and arguably the most effective steroid available.  But it depends on what you want from a steroid. It would seem that everyone would want to use it though some people misunderstand it or simply don’t know how to make the best use of it.

Like the name suggests  -- Primo  meaning “first” or “number one” , Primobolan tops the list of premier tissue building drugs.  By emphasizing the anabolic nature and reducing the harsher androgenic qualities, Primobolan was designed to have as few side effects as possible, which is most definitely the case.   Suppression of the HPTA is minimal and increased blood pressure, liver damage, the risk of gyno, or any ill feeling at all is virtually non-existent with Primo.

Being the most anabolic and the least androgenic of all steroids, it’s pure and clean and pretty damn near perfect.  But there’s a catch.  (There’s always a catch).  Primobolin by itself will not yield big gains.   Muscle growth is slow and solid and without the big gain in size. For this reason people mistaken think that Primo takes a long time to “kick in.”  That is not so.  It starts working immediately, but growing solid muscle takes time.  However, SIZE, is more than pure muscle tissue   -- it’s water, creatine levels, blood volume, etc. And that’s where other steroids will show a quicker response while Primo seems to take its time.  That’s because it’s a pure muscle builder.  It grows muscles the way they grow naturally, through increased nitrogen retention – just at an accelerated rate.

Since Primo works by retaining nitrogen it is essential that you take in a lot of protein in order for it to do what it does.   Eating a sub par diet is a waste.  It’s like buying a Ferrari and using it to make trips to the supermarket.   A high protein diet along with additional protein supplements makes Primo work at its best.

Some people claim Primo is hard on the hairline but it’s no worse than most other steroids.

Primo for Bulking or Cutting

Primobolan is one of few steroids that is ideal for both bulking and cutting.  The truth be told, there really is no such things as “bulking steroid” or a “cutting steroid” it’s just that some generate more water retention than others.   That can work in your advantage if you’re looking to put on weight (even water weight) in order to get your body adapted to more mass. And the feeling of busting out of your shirtsleeves can be fun too.  But beyond water retention, bulking and cutting is more a matter of diet. Primo will not produce fast increases in weight weight by itself, but if calories are increased it’s a wonderful drug for bulking without the bloat. (What some people call a” lean bulk”).   Of course, in a calorie deficit Primo will still create muscle growth, making it a favorite for  competitive bodybuilders in the last few weeks before a contest.

Stacking Primoblan

As great as Primo is, most guys feel they need to kick it up a notch by adding something stronger and in that regard, Primo is  very easy to stack since it goes with anything. There are no contraindications with other steroids and whatever else you’re using, Primobolan will simply add a greater anabolic impact to it.  The most logical stacking choice with Primo would be testosterone. Test goes with everything as well and the combination is a winning one. Not being particularly androgenic (even though, like all steroids, it’s based off of the testosterone molecule) Primobolan  can still cause some suppression since the androgenic quality would be just enough to suppress but not high enough to add more than the  body would produce on its own.  This is one of the criticisms of Primo. For maximum growth, some androgen elevation is needed.  The induced suppression along with the lack of androgen replacement can lead to a slight loss of libido. Adding a little testosterone  rectifies that potential pitfall plus increases greater muscle building potential. Together the two steroids provide all you want and need from a cycle. Stacking multiple injectable compounds is usually unnecessary.

If you’re looking for a “kick start” to you cycle Primo also stacks especially well with fast acting orals.  When using Primoboaln with Dianabol you’ll get the initial  impact of the D-bol along with the sustained solid muscle build up for the Primo. It’s the best of both worlds.  But when using an oral, ALWAYS use a proper liver protection supplements.  (N2GUARD, Protein Factory POST- CYCLE and LIV 52 are among the best and the most popular. Better yet – use all three).   Rumor has it that Arnold took a 100mg shot of Primobolin a day along with 25mgs dianabol tabs a day.   That was regarded as pushing the envelope back in “the day” though by today’s standards it’s pretty mild.  It’s also a pretty good stack.  The two compliment each other well and you can get both the increased size and blood volume along with the superior nitrogen retention and relative safety.

Primobolan For Women

Primo is considered the best choice for women due to its low androgenic qualities and consequent lean gains.  Women tend to want to avoid excessive bulkiness and the smoothness that comes from water retention.  Also, since estrogen creates a “soft” look, steroids that aromatize can destroy the aesthetic they’re attempting to achieve.   One drug which creates hardness without bloating or estrogen buildup is Masteron, but Masteron is a pure androgen. This can lead to the masculinizing side effects most women seek to avoid --  hair loss, body hair growth,  tougher skin, a deeper voice and most disturbing, enlargement of the clitoris.  Since Primo is almost purely anabolic, these sides are kept to an absolute minimum if dosages are kept reasonable. Women usually respond very well to a dosage of 50-100mg per week, although many opt for the oral version who feel it’s better at burning fat, though this is pure speculation and anecdotal. There’s no evidence to suggest as much, but empirical evidence is not without some merit.

Additionally, some woman choose to include other anabolics such as Winstrol or Anavar, but this just redundant.  Mixing too many steroids has no benefit and can be a detriment since it becomes unclear which are working best. If you like Primoblan, use Primobolan. And especially in the case of woman, there’s usually no need for add-ons. A popular recommendation for women would also be to first experiment by using Primobolan on its own, and later venture into a second steroid if necessary.

Primobolan Side Effects

Primobolan has the same side effects as all steroids, just to a much lesser degree.  (Vet substances such as Trenbolone and Equipoise have their own set of problems but that’s a separate issue.).   Some people feel that since Primo is so clean there is no dosage or duration that is harmful. That's simply not true.  Any drug can take a toll on body if too much is used.

One side effect that a lot of people are not aware of with Primobolan is its effect on the kidneys.  It does not directly harm the kidneys but since it’s so anabolic, it keeps an enormous amount of protein (nitrogen) recirculating throughout the body.  That’s great for your muscles but the kidneys still have to remove the waste and after a while it can start to be a strain. So if you’re thinking of doing 500 mgs of Primo a week as a bridge, or as an adjunct to HRT thinking it’s a “free ride”, think again.   Primo isn’t harsh, but it is powerful.  Do not underestimate it and do not think it can’t do any harm if overdone.

It isn’t technically a side effect but another “drawback “ of Primo is its price.  Mg per mg  (and in regard to effective dosages) it’ s the more expensive steroid available.   There is an oral (acetate) version, as well that is NOT liver toxic, but the cost is out of the question for most people.  Not being 17 AA, it doesn’t remain active in the bloodstream for very long, which eliminates the liver strain but requires multiple dosing throughout the day.   An effective daily dosage of the oral version for a 200 pound man could cost  up to $20-$30.  For a 2-month cycle along with all the PCT products and supplements, that starts to add up and it’s the reason almost no one (besides women who obviously can use less) depends on the oral as a “main” steroid.

Primobolan must be used in fairly high dosages but not as high as some may think.  Keep in mind; if you used  only  300 mgs of testosterone you wouldn’t experience much result either.  It comes down to the TOTAL steroid intake.   Therefore, Primo’s effect is dependant on what else you’re using. If you use a base of 400 mgs of testosterone then 400 mgs of Primobolan would be considered the minimum (and often sufficient) dosage.  600 mgs is when you really start to recognize a difference. 800 mgs is the sweet spot. And 1000 mgs can literally transform your body.  More than 1000 mgs however doesn’t seem to have more of an effect.  In general, more than 1500 of steroids TOTAL will not produce significantly greater gains and the side effects increases tremendously at this point.

Keep in mind, even at higher dosages, when using Primoblalan as a main steroid, protein consumption must be high. The Primo cannot make muscle from nothing. Protein is the trigger. So not only must you eat a high protein diet, but also take in protein shakes and preferably some amino acid capsules to take in between meals through the day.  (If using amino’s,  go with those made from hydrolyzed protein and if possible, an ingredient known as Super Plasma Serum. That’s the most potent and works very well with Primobolan).

What many consider the worst side effect of Primobolan is the pain of injection. The injection itself isn’t bad but it creates severe soreness the next day. Since Primo has to be used at least every other day, it’s best to alternate right and left glute and STILL it can really hurt after just a couple of injections.  Not everyone is sensitive to it but in some cases, shooting Primo in the delts has left many a strong man  unable to lift his arms overhead without pain.  Shooting in the thigh can cramp your legs pretty badly.   One must also be wary of claims of UG Primo being “smooth and painless.”  That suggests that it either isn’t Primo or it’s under dosed or cut with something else.

Buying Legit Primobolan.

Primobolan is not as widely available as other steroids and is also the most often “faked.”  (Usually with something cheaper that gives “similar” results like Equipoise.  Or in some cases, 100 mg dosings of Primo are actually 50 mgs of Primo and 25 mgs of test).   Who’d know?  Well, advanced primo users would. But those looking to try Primo for the first time may think they’ve gotten the real deal since they’ll see results and clean gains but it’ll be a shadow of  what pure pharm grade Primoblan can do.

So how can you tell?  These days, checking lettering or serial numbers on the  ampules is not a good indicator.  They can be counterfeited too easily.  Primoblan was made by Schering  but branched out to the Bayer company, so it now goes under both names. Both are legit, though the Schering comes in a box and it’s a lot less likely that a bootlegger is going to go through the trouble of making ampules AND a box, so the Schering may be your best bet. (There is no pharm grade Primo that comes in a vial).

There are some good UG labs making quality Primo however.  One thing you want to avoid with UG labs is any claim of a 200 mg per ml dosage.  Primo has a heavy molecular weight which is why it can only have 100 mgs per ml. This is also one of the reasons it creates soreness at the injection spot.  Any company that claims a 200 mg per ml dosage should be considered suspicious.

Naturally, we can’t provide sources but a little investigation shouldn’t be too difficult.  A simple google search of key words such as  “Primo”, “buy on line”,  “western union” etc,  should pop up some places.  (Western Union is a good search word since most places only accept WU payment).

Of course, nothing is guaranteed, which is why you may want to contact other steroid users via forum message boards and such and feel out what people are using and recommending and what they’re saying to stay clear of. They’ll always be those who over praise or over criticize, but at least it’ll get you in the ballpark.

If you’re looking to bulk up fast, you may want to pass on Primo.  But if you want something that is going to bring steady , solid gains over the long run, it’s the wisest choice.  If your goal is high quality gains, or even just something to give your progress a boost without  worry or too many health concerns, then Primo is the truly numero uno.
