Dihydrotestosterone (DHT) (referred to as androstanolone or stanolone when used medically) can also be used in place of testosterone as an androgen. The availability of DHT is limited; it is not available in the United States or Canada, for instance, but it is available in certain European countries, including the United Kingdom , France , Spain , Belgium , Italy , and Luxembourg .  DHT is available in formulations including topical gel, buccal or sublingual tablets, and as esters in oil for intramuscular injection.  Relative to testosterone, and similarly to many synthetic AAS, DHT has the potential advantages of not being locally potentiated in so-called androgenic tissues that express 5α-reductase (as DHT is already 5α-reduced) and of not being aromatized into an estrogen (it is not a substrate for aromatase).
**B12, no this is not a steroid , but many items we add to our cycles are not steroids. As women are also necessarily a bit more limited to what they can use, we have to find other options. This is not a requirement to this cycle, we are simply providing you with quality options. If B12 is used, it is highly recommended that you choose injectable B12, specifically Methylcobalamin as it is by far the most effective. This will provide a massive boost of energy to your training and greatly improve recovery, which is the most important factor.
