Pros go for the best

Primobol 100 is reportedly perfect for gaining and maintaining quality muscle mass. It is thought to have stronger affinity for androgenic receptors (AR) than testosterone. Primobol is also thought to burn the body fat – it is considered one of the best pre-contest substances. Primobol cycles must be long (about 12 weeks), otherwise the results can be disappointing. It is clearly one of the most popular anabolic substances for cutting cycles.

Lean muscle mass

Primobol 100 offers the ideal combination of very lean and long-lasting muscle mass gains plus practically zero complications/side effects. In this respect it is the best of MegaGear supplements.

Most muscle growth comes in the final weeks of the cycle. We presume this may be the result of active substances accumulating in the body. This pattern has been observed by most users, as well as in tests of MegaGear products.


Some individuals respond more and others less to xenoandrogens. It seems that some people with history of anabolic steroid use are less sensitive to MegaGear supplements.


Healthy liver is extremely important for proper digestion and hormonal balance in the body. Using a product like Liv 160 once in six months will increase your chances for growing muscle mass and burning fat.


When used on its own (no combination with other MegaGear products), 3ml/week are sufficient for a 200lb (90kg) man. If another oil-based product is used along with Primobol 100, the dosage should be lowered to 2 ml/week. Overdosing can lead to health problems! Do not use longer than 12 weeks. Stay clean of Primobol 100/other MegaGear supplements for a period of at least 1 month after the cycle.


Primobol 100 can be combined with most MegaGear supplements for better results. Typical stacks involve Danabol, Oxandro and Testobol 250. Do not combine more than three MegaGear supplements in one stack!
