Every athlete should set successive training goals. In the case of many different sports, these mainly concern broadly defined strength, speed or endurance. The only exception is figure sports, where the visual appearance of the muscles and the overall shape of the figure also play an essential role. This is where progress can be downright complicated at some point. So, if someone cares about getting the best possible results, they must reach for specialized means to take the next step forward.

You can find many exciting proposals in the category of such preparations. However, a potential game-changer has recently appeared on the market. It is the high-end preparation Mass D-10 from the renowned company Core Labs. As the manufacturer declares, it is supposed to be a solid and adequate anabolic preparation that will bring your body’s capabilities to a whole new higher level. A glance at the composition of this formula shows why such a statement can be fully justified.

Admittedly, the composition of this formula is relatively short, as it contains just three substances. Nevertheless, one of them deserves special attention and a longer description:

-2a 17a-dimethyl-5a-androst-3-one, 17b-ol – let’s start with a few words of introduction. This compound is known to advanced athletes as methasterone or superdrol. Its main advantages can be put in one sentence. Well, it is the most potent prohormone created, redefining the body’s anabolic capabilities. In addition, Cole Labs has changed how it is produced, so it has obtained a compound of even higher purity and, thus, greater effectiveness. Because of this, the very supplementation of this compound has taken on a new meaning. Now, methasterone can help you quickly gain lean muscle mass even more effectively. Mass D-10 capsules will not only crank up your anabolism but, at the same time, strongly inhibit all catabolic processes. As a result, your muscles will be left with only one pathway, which will be the pathway of rapid growth. Of course, methasterone can provide additional effects and optically enlarge your figure. Thanks to it, the perfect outline of your muscles will further enhance the assets of your built musculature. What is clear is that you will also be able to count on solid vascularization and a “bulking” effect.

-NAC (N-acecyl-L-cysteine) – potent anabolic compounds that can harm liver function. Therefore, during the supplementation period, care should be taken to provide additional protection and support for the work of this organ. One of the most popular substances in this regard is N-acecyl-L-cysteine. NAC is very effective in supporting liver function and contributing to faster removal of toxins and other undesirable compounds. In this respect, the action of NAC is ideally suited to the needs of those taking advanced forms of supplementation.

– Vitamin E – During any supplementation cycle, you should take special care of your body to benefit from the agents you use. Therefore, during such a period, among other things, it is worth enriching your supplementation with vitamin E. Its task is, for example, to improve the work of the cardiovascular system. Interestingly, such a property also affects the effectiveness of supplementation itself. This is because vitamin E can contribute to more efficient transport of nutrients (among other things, by improving their solubility). As a result, the body can use the active substances supplied to it.


The maximum daily dose of Mass D-10 is one capsule. Due to the high action potential, the preparation should be taken in short cycles.


Mass D-10 from Core Labs, featuring potent components like Methasterone, is a powerful anabolic agent that enhances lean muscle mass and overall muscle definition. Given the strength of such compounds, following a disciplined supplementation cycle, complete with on-cycle support and well-structured post-cycle therapy (PCT), is crucial. Here’s a suggested protocol:

Supplementation Cycle for Mass D-10:

On-Cycle Phase:

Duration: Given the potency of Methasterone, a cycle should last no more than 4 to 6 weeks to prevent excessive strain on the body.

Dosage: The maximum daily dose is one capsule. It is typically taken with a meal to enhance absorption and minimize potential gastrointestinal discomfort.

On-Cycle Support:

Liver Support: Due to Methasterone’s hepatoxicity, taking a liver support supplement like NAC is crucial. Additional liver aids, such as TUDCA or Milk Thistle, may also be beneficial.

Cardiovascular Support: Given the inclusion of Vitamin E, additional support with Omega-3 fatty acids and CoQ10 may help maintain cardiovascular health.

Off-Cycle Phase:

Duration: An off-cycle period of at least six weeks is recommended to allow the body to recover and restore its natural hormonal balance.

Maintenance: Maintain a balanced diet and moderate exercise regimen to preserve muscle gains.

Post-Cycle Therapy (PCT):

Testosterone Restoration: Use natural testosterone boosters like D-aspartic acid, Fenugreek, or Ashwagandha to help stimulate endogenous testosterone production.

Estrogen Control: If necessary, implement an aromatase inhibitor to manage estrogen levels and mitigate any potential estrogenic side effects.

Cortisol Management: Consider cortisol blockers to prevent muscle breakdown and promote recovery.

Protective Measures:

Comprehensive Multivitamin: Ensure you get all essential nutrients, supporting overall health.

Antioxidants: Additional antioxidants can help combat oxidative stress during intense training cycles.

Joint Support: Supplements like Glucosamine and Chondroitin may benefit from increased physical stress.


Blood Work: Conduct blood tests before, during, and after the cycle to monitor liver enzymes, lipid profiles, and hormonal panels.

Adjustments: Be vigilant for any adverse effects, be prepared to stop the cycle and consult with a healthcare professional if necessary.
