As this anabolic steroid is not very liver toxic, in-fact it is quite mild it can be used for extended periods of time; if you are not susceptible to DHT based side-effects you could reasonably supplement with Proviron the entire duration of your cycle. While it can be used for extended periods, as we will see dosing protocol can vary dramatically depending on the purpose for which it is used. If Proviron is being used simply as a quasi-anti-estrogen medication then a mere 25mg per day may be all you need but many will find 50mg to be needed if their cycle contains a high dosing of aromatizing steroids. For those who are supplementing for additional beneficial purposes higher doses may be needed; although 50mg will provide them solid effects a slightly higher bump may be needed. If you choose to use Proviron this is something you may need to play with as individual response will vary greatly. For the individual who supplements for the purpose of bridging, a rather common purpose of Proviron use, doses will necessarily be much higher, ranging from 100mg-150mg per day if the individual is going to obtain the desired effect and benefits.
If you believe you are ready for one of the following cycles you will have many cycles under your belt, supplemented with numerous anabolic steroids , 5 is a good number and have learned how to not only have successful cycles but ones in-which side-effects are controlled. Further, to be ready for an advanced cycle you will be one who is able to maintain more gains after a cycle than you lose. Some gains will always be lost after a cycle is complete, this is a given but maintaining a majority of your gains is possible. If this is not possible for you then you need to reexamine your use, your diet and perhaps even your training.
