Most PH's will shut you down, just like an AAS will. Test is one of the safest injectables you can use and will give you solid lasting gains. Injectables in general are safer than orals because they bypass the liver keeping your liver healthier. They are also more effective because orals get broken down by the liver before being released into the blood stream, but injectables go straight into the blood stream through the muscle. I would not run another solo oral compound ever again. Test is cheap, easy to find, makes you feel great, keeps the libido in overdrive, battles lethargy, gives a great pump and focus, and much more. If you're going to shut your body down, get the most out of it and lengthen your cycle with test. Just my $.02
