Primobolan Information

What is Primo?

Primobolan (also known as Primo) is the common name given to the drug Methenolone Enanthate. It is an injectable steroid that is rather mild in nature when compared to other anabolic steroids (AS), and is generally seen as a more steroid more anabolic in nature rather than an androgenic one.

Primo also comes in an oral form called Methenolone Acetate, however due to the non-alkylation of the methenolone in this form, it is not realistically a very useful drug for the male bodybuilder as the liver will mostly destroy the methenolone acetate ingested.

Properties of Primo

Primo is quite a unique steroid of which there are no other steroids quite like it. Firstly, Primo does not aromatise to estrogen, thus estrogen related side-effects are not seen in Primo use.

This means that acne, water retention, gyno, etc, are all not concerns when using Primo. Thus primo becomes a very useful steroid for those who are easily prone to undesirable side effects such as acne and gyno.

Due to the low water retention seen in its use, Primo is often used effectively when cutting. It is not only effective when cutting due to low/nil water retention, bit it also proves very useful when cutting due to its anabolic nature and nitrogen retention properties, which basically means that it holds onto muscle very well when in a calorie deficient mode as one would be when cutting.

Many claim Primo to be side-effect free, except for experiencing slow but steady, quality and retainable muscle gains when on it for longer periods of time (>8weeks). Due to lack of water retention, etc, the gains you see on Primo will be quality muscle gains. Gains on Primo are easily kept, however although Primo is not as harsh on your HPTA (hypothalamus-pituitary-testes axis) it will shut you down.

Do not make the mistake of thinking that post cycle therapy (PCT) can be avoided with Primo use, because this is not the case. Recovery should be easier from Primo than most other AS, but proper PCT of Nolvadex and/or Clomid will be necessary.

Primo for many does not generally affect one’s libido; however for some it lowers it if used in a cycle without test. Usually I find that this is the case with heavier users of gear, i.e. those that use larger amounts of test and/or stay on AS for longer periods of time. In such cases, if test is not used in the cycle with Primo, appropriate meds such as Viagra, Cialis, etc may be needed on hand in case of libido problems. However as said, for most recreational AS users, loss of libido generally is not a problem with Primo.

Primobolan Cycle and Dosing Info

Although Primo is a quality steroid, as said it is rather week. Also due to the fact that it contains (in injectable form) an enanthate ester, anything under 400mg per week is rather a pointless use of Primo and a waste of money. Generally with AS, more does not always mean better (due to side-effects and other issues), however in the case of Primo more does definitely equal better.

If stacking Primo with testosterone, 400-800mg per week will be an effective dose, with obviously the higher doses being the most effective. Primo will have two main effects in such a stack. Firstly it will seem to amplify the effects of test, so 500mg of test enanthate may seem like 750mg or more. Secondly, Primo is very forgiving with one’s diet. Quality muscle can still be obtained at a steady rate even with one’s diet being off from time to time. However, with a spot-on diet, Primo and test will work wonders.

For those who would want to use Primo on its own or without test, you would really need to use a minimum of 600-800mg per week. If you can afford it, 1000mg per week of Primo will highly reward the user.

Some people often ask about using Primo with Trenbolone. This can be done, however without test one must realise that you are likely to be quite shut down, and it is likely you would need some sex medicines as well as HCG. Despite this, for those that want a test-less cycle, Primo and Tren is a great cutting cycle. My ultimate cutting cycle however is one that incorporates Primo, Test Prop and Tren Acetate. Another very good cutting cycle that is test-free would be Primo (600-1000mg per week) with Anavar (60-80mg per day).

Due to the enanthate ester that is attached to the Methenolone base in Primo, it really should not be run for less than 8 weeks. In my opinion, I would run Primo for a minimum of 12 weeks, also bearing in mind that the Primo really kicks in at about weeks 5-6, where a real fullness of muscles is experienced.

Primo is also useful at a high dose for those who use higher doses of test and experience appetite loss from this. Primo doesn’t cause such appetite loss, thus when bulking this can give a chance for diet to be spot-on.

Primo does suppress and shut you down as said, however it is roughly about half as suppressive as test, so a 12 week Primo cycle would shut you down similar to a 6 week test cycle. For this reason, Primo alone can be run up to 20 weeks without fear of a very difficult recovery in PCT.

Due to the enanthate ester, PCT should be run approximately 14-18days after last Primo injection.

Here are some example Primo cycles:

Primobolan Ampule and Box

1) Test-free cycles

  • Primo 600-800mg pw weeks 1-12; Anavar 60mg ed weeks 1-8
  • Primo 600-800mg pw weeks 1-12; Tren Ace 75mg eod weeks 1-6
  • Primo 800mg pw weeks 1-12; Masteron 400-600mg pw weeks 1-14
  • Primo 1000mg per week up to 20 weeks (expensive)

2) Primo cycles with Test

  • Primo 600mg pw weeks 1-12; Test enanthate 500mg pw weeks 1-12
  • Primo 600mg pw weeks 1-12; Test prop 100mg eod weeks 1-14; Tren enanthate 300-400mg pw weeks 1-10 (Superb cutting cycle for advanced user)

There are many other different cycles you could do; these are just a few examples. Generally, the amount of Primo you will use in the cycle will be down to how much you can afford, and how many injections you mind doing. As said though, generally with Primo, the more you can do, the better, but a minimum amount would have to be no less than 400mg/week.

Legitimate Primo

The best Primo money can buy (as is the general rule with any AS) is pharmaceutical grade Primo. By this I do not mean underground lab set-ups that use pharma-grade procedures, but rather pharmaceutically produced AS. Primo originally came made by Schering, in amps of 100mg, one amp per box.

Due to the high cost of Primo however, these soon became faked, and along with Viromone are probably the heaviest faked product on the AS market. It is extremely hard to get legit Primo, and harder to be able to spot the real Schering from the fakes. However, if you do get legit Schering Primo, it is the best that money can buy.

Due to Primo being heavily faked, it is likely that you would want to use an underground lab’s Primo. I can only speak from my own experience and those I know and trust, and so can certainly say that British Dragon (BD) Primobol 100 is a solid and trusted product, and although BD products are faked, a good source will always have access to legit BD Primo. There are other good UGL set-ups who also make Primo.

Fast-acting Primo?

Schering did used to make a fast-acting primo, that is, the Methenolone Acetate version as an injectable. However this was 20mg/ml and is no longer made. Some underground labs, particularly in the US have recently been making injectable methenolone acetate. However beware, as there is a reason that it was originally made at 20mg/ml; anything from 50mg/ml and above of this product will cause severe injection site pain following injection, and furthermore pretty much everyone I have read of who has tried this form of Primo at such concentrations will get flu like symptoms after every shot for a day or so. Thus the reason why methenolone acetate is not marketed by any major underground labs.
