Ran his mast p for 12 weeks @ 125mg 4x per week. Very little pip, but I was loading a 3ml syringe full with that and a few other compounds, So I'm sure the pip was from the amount of oils being pinned and not from the mast alone. Had oily skin, saw my body lean down, and more veins popping. I'm normally a pretty passive dude, but found myself getting very irritable and wanting to argue with people at work more often.

Mastolab-100 is an injectable anabolic steroid made by 7Lab Pharma, the active substance of which is Drostanolone Propionate, a derivative of dihydrotestosterone and a biological agent with a biological effect similar to it, which is characterized by very pronounced androgenic properties with moderate anabolic effects.

It does not aromatize, exhibits antiestrogen activity and increases testosterone levels. Increases muscle density and strength, reducing the amount of subcutaneous fat. It is used in a variety of sports, especially in preparation for competitions in bodybuilding and not only.

Usage and Dosage

Drostanolone Propionate has been used successfully to fight breast cancer. However, the high likelihood of virilization with constant intake in the doses necessary for treatment forced to abandon this drug in the treatment of women. But male athletes successfully use it when it is necessary to achieve an increase in strength during weight loss due to fat burning and a pronounced diuretic effect.

Due to these properties, Mastolab-100 has won recognition among bodybuilders as an exceptional drug for building high-quality muscles and removing excess water from the body. It also helps athletes stay in their weight category with a qualitative increase in muscle and improved physical performance. This is one of the most popular anabolic steroid among athletes.

This anabolic can be used both in combination with other drugs, and separately. In the latter case, the dose usually increases slightly. Men are recommended to take this steroid from 300 to 500 mg per week every other day or every three days, since the active substance acts up to three days. Due to the high probability of virilization, women are not recommended to exceed a dose of 25-50 mg/day and take injections more often than every three days.

Beginners should not increase the dose if they had not taken such steroids before. Such a cycle usually lasts from 6 to 10 weeks, or longer for 8-12 weeks.

Mastolab-100 does not aromatize, therefore, there is no need to take antiestrogen drugs. This anabolic and Stanolab-50 (Stanozolol), which also does not retain water in the body, are well combined. In such a combination, Stanolab-50 is taken 50-100 mg every day or every other day, oral Stano-Lab 10 should be increased from 10 to 30-40 mg during the week. The drug in tablets, like injections, gives good results in combination with synthetic derivatives of testosterone. To build high-quality muscles, a combination of Boldelab-200 with this steroid is interesting. However, it should be noted that this combination significantly increases the appetite, which some athletes may be prevented from following a sports diet.

This steroid and Primalab-100 (Methenolone) are very similar in action, and in combination they provide tangible progress, but Primalab-100 gives a significant effect with a fairly long-term use, so you should take them in conjunction with a long course (about 12 weeks).

If you have not used such a drug before, then Mastolab-100 reviews of those who have already evaluated the effectiveness of this drug will certainly help you draw conclusions about the advisability of using it in your training system. This steroid has been successfully used by many athletes for quite some time and helps them achieve the desired results.

Side Effects and Contraindications

Mastolab-100 has a pronounced androgenic effect. Basically, this can be manifested in increased hair growth on the body, baldness of the head, and the appearance of other male external signs, so women should take injections very carefully. Practice shows that subject to dosage and frequency of administration, it does not show side effects

According to the results of a fairly long-term use and laboratory studies, this anabolic and androgenic steroid drug is considered one of the safest injectable drugs for sports. Therefore, to build muscles and for cutting, it is often taken in combination with Oxano-Lab 20.
