Product Description

Musclebuilding Anabolic Steroids Methenolone Enanthate CAS: 303-42-4 Primobolan White Powder




Among athletes Methenolone Enanthate is generally known as a mild steroid which provides slow steady gains in quality muscle mass while not being harsh on one's system. It is often used in cutting cycles when the athlete is in a calorie restricted diet and trying to preserve muscle mass while shedding bodyfat. Primobolan is notorious for being very effective in this particular case. It is also popular for athletes looking to add a little muscle and strength in speed related or weight restricted sports. Primobolan is not aromatized by the body and therefore doesn't convert to estrogen. Therefore, estrogen related side effects shouldn't be a concern when taking this agent and users need not worry about taking any anti-estrogens when running it by itself.

Effect Methenolone Enanthate:


The effect of methenolone enanthate(10 mg kg−1 thrice-weekly) on total body nitrogen, potassium, phosphorus, and body-weight, muscle protein synthesis and food conversion efficiency was measured in Wistar rats during the period from weanling to maturity (22 to 64 days of age). Treated male rats exhibited a lower rate of weight gain, increased kidney weight and decreased testicular weight when compared with controls. No differences in total nitrogen, potassium or phosphorus were observed. Treated female rats had significantly increased body-weight, total body nitrogen, phosphorus, and potassium compared with female controls although, when expressed as a percentage of body weight, phosphorus content was higher in controls. Treated female rats had increased food conversion efficiency expressed relative to total body weight gain or total body nitrogen gain. Rates of synthesis of mixed skeletal muscle protein, measured at the conclusion of the study, indicated that treated females had a significantly increased rate of synthesis when compared to female controls. There was no significant difference between treated male rats and control animals.





For men, injectable dosages should be 600-800mg per week or higher, and oral dosages should be around 75-100mg per day.

For women, using only oral primobolan. Around 10mg per day seems to be a good amount to start with. You should play with the dosage but never go over 20mg per day.

5. Expectations and Results From Primobolan Dosages

Primobolan is a very weak anabolic steroid and therefore impressive lean muscle and mass gains with Primobolan should not be expected. Even higher and higher doses of Primo will not elicit the same types of lean mass gain that a miniscule dose of a very powerful anabolic steroid like Trenbolone would provide, for example.

Therefore, Primobolan is often stacked alongside other anabolic steroids, and many experienced anabolic steroid users would never utilize Primobolan solitarily on its own as it is well known as being a very poor anabolic steroid to be run on its own. With all of this being established, Primobolan’s gains in and of itself is known to be quality lean muscle gains without the added water retention or possible fat gain/retention.
