What is Mast P 100?

Xeno Labs Mast P 100 contains drostanolone propionate that is a synthetic derivative of dihydrotestosterone. This makes  Mast P 100 not aromatize in any dosage and therefore cannot be converted to estrogen. Because of it, Xeno Mast P 100 a predominantly androgenic steroid. The bodybuilder can increase his androgen level without risking increasing his estrogen levels. Mast P 100 is an androgenic steroid that contains drostanolone propionate to block the aromatization of testosterone in your body. This effect is useful to maximize the yield of workouts.

What is Mast P 100 used for?

Xeno Labs Mast P 100’s anti-estrogen effect stops the transformation of free testosterone. This impact inhibits aromatization enzymes and keeps your testosterone level stable. Decreasing estrogen and high testosterone levels lead to fat loss, pure muscle mass, and evident improvement. Fortunately, drostanolone propionate has fewer side effects in contrast to other steroids. Actually, Mast P 100’s synergy with aromatize inhibiting effect will expand other anabolic steroids’ observable benefits due to anti-estrogenic properties. While some of the anabolic steroids are able to transform estrogen, Mast P 100 blocks this transformation.

Competitive bodybuilders who have been around for a while will surely get shiny eyes when the name “Masteron” is mentioned. Masteron was long considered one of the most popular competitive steroids. Switching to other preparations, e.g. the French “Permastril” or the English “Masteril” was not possible because Masteron was indeed the last preparation containing drostanolone propionate on the market.

How to use Mast P 100?

Dosages of 50-100 mg per day are usually injected within the last 4-8 weeks before a championship. Extremely good results can be seen with 100 mg daily. Mast P 100 is rarely used in the build-up phase. If you are interested in a qualitative increase in muscle, inject 100 mg every second day or every other day for a maximum of 12 weeks depending on the level of development and combine with 250-750 mg testosterone enanthate/week or alternatively 50-100 mg testosterone propionate every second day. Another stack of 200-400 mg boldenone undecylenate/week or 200-400 mg methenolone enanthate/week can also accelerate the increase in solid muscle mass.

This highly androgenic Mast P 100 is not recommended for women, but within the last month before a competition, competitors inject 50 mg every other day or three, making incredible progress in terms of muscle hardness and fat loss. If there are signs of virilization, the intake should be stopped immediately and countered with spironolactone if necessary.

Beginners should not use Drostanolone Propionate due to its high penetration. There are more suitable steroids for their needs, especially Depot Testosterone.
