Methenolone, Primobolan is an oral/injectable anabolic steroid that is used by bodybuilders to encourage increased lean muscle mass; prevent muscle wastage and enhance physical performance and strength.
In fact, thanks to its long-acting and mild anabolic effects – plus its low androgenic properties – it is considered one of the safest anabolic steroids around, as it can confidently be used by both men AND women without fear of liver toxicity or aromatization.
But that’s not all it can do…
It has been found to be beneficial in the treatment of underweight children (malnutrition), premature infants, osteoporosis, and sarcopenia.
Chemical name – 17ß-hydroxy-1-methyl-5a-androst-1-en-3-one acetate.
In its liquid form, it is known as methenolone enanthate. As an oral tablet, it is known as methenolone acetate.
Active life: oral methenolone (4-6 hours); liquid (injectable) methenolone (10-14 days).
Difference between Primobolan depot and oral Primobolan: Primobolan depot is an injectable version of the hormone which is attached to the large enanthate ester (production of this stopped in 1993 so any injectable versions you find are from underground labs). Primobolan is comprised of the same active steroid hormone in Methenolone; HOWEVER, it is attached to the small acetate ester (making it suitable for oral use).
Methenolone is a derivative of DHT (or to be more precise – is a structurally altered form of DHT). It contains an added double bond at carbon one and two, which helps to increase this hormone’s anabolic nature. It also carries an additional 1-methyl group that protects it from hepatic breakdown. The presence of the acetate ester further protects it from hepatic metabolism.Its oral form is especially beneficial, as it is the only oral steroid to NOT be a C17-aa steroid. Now whilst the lack of C17-aa means it’s not toxic to your liver, it also means it is mild/considered weak compared to other steroids i.e. most men won’t experience the same level of anabolic activity.That is why a lot of men prefer to use Primobolan Depot – as the injection is stronger – whilst women usually stick to the oral form due to these very same mild effects.In many ways, Primobolan works like other anabolic steroids. It boosts protein synthesis (to a degree) and it will moderately increase your red blood cell count.However, it has got three distinguishing features that make it different from the others:
It dramatically improves nitrogen retention, ensuring catabolic states are avoided and that you are able to successfully build lean muscle tissue. True these gains won’t be massive, but they will still be impressive.
It has got a strong binding affinity for androgen receptors which has been linked to direct lipolysis. Now, whilst all anabolic steroids can increase your metabolic rate, Primobolan is believed to directly support fat loss, making it perfect for cutting.
Studies have found that it can significantly enhance your immune system. In fact, it has successfully been used in the treatment of AIDS, offering individuals an immunity boost as well as protection from muscle wastage.
Primobolan dosage and cycles
The ideal Primobolan dosage for men is approximately 200-400mg per week, or 50-150mg per day (if you’re competing). For women, this is dramatically less at just 50-100mg a week (although some studies suggest 25-75mgs per day is safe).
Stacking: it is best stacked with Deca Durabolin, Testosterone, Trenbolone, Masteron, Anavar, Winstrol, Dianabol, Clenbuterol, T3 or Anadrol.
Towards the end/after the end of your cycle, it is suggested that you use Nolvadex, HCG or Clomid, as this helps to enhance the bioavailability of any other steroids you have used during your cycle, whilst preventing any estrogenic side effects e.g. oily skin, acne, bloating or gynecomastia.
Due to its reputation for being a good fat burner, Primobolan is often used by athletes between cycles – during their ‘off-time’ – as it helps them to maintain muscle mass and any strength gains they’ve made. In fact, doing a Primobolan cycle for pre-contest cutting is not uncommon amongst competing bodybuilders.
Typical Primobolan cycle – no matter the amount you take – the low 50mg a day to the competing 100mg – Primo is usually used as part of an 8-week cycle. Note here how we said ‘part of the cycle’? Well, this is because Primo’s total use should not extend beyond 6 weeks. As a result, many athletes will split the cycle and will use multiple anabolic steroids e.g. men often start off with Sustanon 250 and Anadrol for the first 2 weeks; Sustanon 250, Anadrol and Nolvadex from weeks 2-4, before switching to Sustanon 250, Primobolan and Nolvadex from weeks 5-8, and then finishing with just Nolvadex for 2 weeks.
