  • Ideal for shifting from one cycle to another and for the PCT

  • Non-toxic to the liver
  • Suitable for long-term use

If you are looking for a product that is extremely powerful and you do not want to look for it among anab.s, OSTAPURE surely wins. A team of experts in BlackStone Labs and in particular the real athletes, created an extremely powerful formula supporting muscle growth, fat reduction, prevention of damage to the musculoskeletal system, the effects which are comparable with AS. In one thing, however, OSTAPURE is different from ASs. By its consumption, you do not risk any health damage. It represents an ideal choice if you want to get quality muscles, but you do not want to worry about your health. Have you ever wondered why the American bodybuilders are the best ones in the world? It is because for years the prohormone supplements, such as OSTAPURE, are available for them. Thanks to us you can try the positive features of this product yourself!

OSTAPURE is a Selective Androgen Receptor Modulator (SARM). SARMs have the ability to stimulate the androgen receptor in the same way as ASs do but with one exception, they do not affect the natural production of tste. OSTAPURE has the same anab. effect as tste, but no negative side effects. Therefore it is an ideal aid for the period of transfer between cycles, the PCT, and is also suitable for improving the performance in women (dosing of 1 capsule a day). In addition to the anab. properties and a direct effect on muscle growth it has been shown to reduce body fat.

SARMs do not aromatize, but the levels of serum estra occurred slightly elevated. This value was, however, so low that you do not need to worry. But if you want to have an absolute peace of mind, you can include a small amount of the product called Eradicate.

OSTAPURE | muscle growth

Ostapure is the most anab. product from the category of SARMs. It is popular especially with people who are trying to gain muscle mass. Muscle gains are similar to ASs. Your muscles will be thick and hard and without any fat! Because it does not limit the natural secretion of tste, your muscle gains will be permanent. Prepare to gain 2.5-3 kg of pure muscles only after a single cycle and without the risk of negative side effects.

OSTAPURE | weight loss

OSTAPURE is the ideal product for those who want to reduce the amount of fat. If you are trying to lose weight, lack of calories and fat in the diet decreases also the production of IGF and tste. With OSTAPURE you do not need to be afraid. You will still have enough strength, energy and sexual drive, while losing weight.

OSTAPURE | recomping

Recomping means rebuilding your figure. OSTAPURE is one of the most effective supplements for this process. OSTAPURE allows using the calories from fat so that the caloric intake is led directly into the muscle tissue. One of the most important things in recomping is time and patience. If you are trying to achieve several objectives at the same time, it requires a longer period of time. OSTAPURE is taken orally, but has no effect on the function of the liver, therefore, is suitable for long-term use.

OSTAPURE | injury prevention

Scientific studies have shown that OSTAPURE has a positive anab. effect on bones and skeletal muscle tissue. This means that it is suitable for use in certain diseases and damages of muscles, tendons and joints, such as osteoporosis. It is also a useful aid in the period of recovery and rehabilitation.

    Ostarin habe ich wegen Rekonwalescencion nach dem Unfal gekauft. Es ist meine erste Erfahrung mit Sarm. Bis jetzt nur Amino, Kreatin, Protein,... Nach 3 Tagen hate ich mehr kondition und merkte eine bessere zirkulation des (Waskularität). Alles ist sehr einfach gegangen. Nach zwei Wonche bemerkte ich auch deutlich besseren Muskelaufbau. Definition war besser, und steinharte Bizeps. Super
