Physicians may prescribe AAS to address conditions like anemia, muscle weakness, or testosterone deficiencies. If I wanted to blast a little bit for some increased gym gains what would you bump it up too? I take TRT for all its benefits and plan to be on it for life, but I also am a body builder and do enjoy my increased performance. And if you do decide to explore cruise and blast, do it with your eyes open. You're not optimizing therapy, you're choosing to use steroids. If you're on TRT and genuinely happy with your health but wondering about performance enhancement, at least be honest about what you're considering. This again led them to the use of the "blast and cruise" technique. Look, I'm not going to sit here and tell you that nobody should ever use supraphysiological doses of testosterone. You blast, you make gains, you cruise, and you try to hold onto those gains. You're already managing your protocol, getting bloodwork, and you're past the mental barrier of "using steroids" since you're on doctor-prescribed testosterone anyway. That's the kind of progress that takes years at natural testosterone levels, compressed into a single cycle. It is believed that Testolone has the anabolic properties similar to testosterone while still maintaining the safety profile. As with any steroids, it is important to assess the safety and suitability prior to usage. Bringing a blast and cruise cycle to a halt, is however a very difficult affair. Cruising in total is pretty much consistent with low-dose testosterone, no matter the chosen steroids. There are different blast and cruise cycles, which are adjusted by the size of the user, his aims, and pain threshold. For instance, a normal blast might be 500mg of testosterone enanthate per week; 400mg of Deca-Durabolin per week; and 50mg of Dianabol per day for the first prescribed week of the cycle only. The blasting phase concentrates at the use of yet higher doses of AAS in a bid to yield even superior muscle and strength mass. These are distinct from corticosteroids, which are used to manage asthma or inflammation and do not offer muscle-building or performance-enhancing benefits. Say you run 1000mg testosterone per week with 50mg Winstrol per day for 16 weeks. Most people will only do a couple of blasts a year to keep risks and health at check. The "blast" phase consists of a period where more substances are used and doses are higher. A cruise phase can be actual TRT dosages, slightly above or well above these dosages, depending on your size and blast doses. Several users on online forums have reported this same issue after starting testosterone therapy or anabolic cycles. Cruising helps keep your testosterone high enough to avoid fatigue or muscle loss, but low enough to reduce stress on your body. A blast puts your testosterone levels way above normal, so you grow faster. After that, the dosage will be reduced to a much lower dose for the cruising period, which could last anywhere from weeks, or longer. This period could last anywhere from weeks, or longer, and will include a much lower steroid dose. For the blasting period, most cycles will consist of a very high dosage of the chosen steroid, around 100 mg per day or more. A Blast and Cruise cycle is a cycling program specifically designed for bodybuilders to maximize and optimize muscle gains while minimizing body fat levels.
