Syringe Filters are luer lock or luer slip compatible filters that connect directly to a syringe. They are available in a multitude of pore sizes, for our purposes we need .2 or .22 micron. Anything larger and microorganisms will be able to pass, and sterility will not be achieved. You would draw directly from your brew, connect the filter and a 20-23g needle to your syringe, and inject into a sterile vial (one you have sterilized, or have bought pre-sterilized). If you use larger than a 20g needle, you risk cleaving the stopper into the vial and you'll have pieces of your stopper floating around in your vial.
The side effects of Halotestin include natural testosterone suppression, and it will be extreme. However, the reason for suppression is a bit of a mystery with this steroid due to an inconsistent suppression of gonadotropins. Despite this fact, it will suppress natural testosterone production significantly, making the inclusion of exogenous testosterone necessary for most men. Those who do not include exogenous testosterone therapy will fall into a low testosterone condition. This will occur regardless of genetic superiority and can come with a host of bothersome symptoms. Regardless of the severity of symptoms, low testosterone is an extremely unhealthy state. Those who include exogenous testosterone will avoid this low level outcome. The form of testosterone you choose is inconsequential. All that matters is that you provide your body with what it needs.
Once the use of Halotestin comes to an end and all exogenous steroidal hormones have cleared the system, natural testosterone production will begin again. Natural recovery assumes no prior low level condition. It further assumes no damage was done to the Hypothalamic-Pituitary-Testicular-Axis (HPTA) due to improper steroid use . While production will begin on its own, levels will not return to normal for several months. For this reason, the implementation of a Post Cycle Therapy (PCT) program is often recommended. This will greatly stimulate natural testosterone production, and ensure you have adequate amounts of testosterone for proper bodily function. It will not return you to normal on its own, this will still take several months, but it will speed up the process and ensure a much smoother recovery.
