wait PH's are the really thing or reall close?
They are methlyated oral designer steriods. Basically which is why they work unlike any of the other crap you can buy at GNC or so. They can give you terrible side effects post cycle. They can give you side effects during cycle. If you know how to use support supplements prior to going on cycle with them, and when done using proper post cycle therapy, then you would be fine. Post cycle therapy has its own section dedicated to it on this site. But my first warning is that some of the stuff you take during post cycle therapy is just as hard to get as illegal gear, unlike the designers which are legal and easy to buy.
If I were you I would start with just a test booster and see how you like it. The natural progression should be IMO:
1. Weight lifting and taking basic supplements like creatine, NO, BCAA's. This way you build base muscle and learn good form. You also learn about proper nutrition, sleep, and how your body feels when its gaining weight and strength. This is where you get your DIET IN CHECK!
2. You hit a plateau as we all do. You change your diet around. You up the calories, you up the protein, you up the carbs. You may try a pre-workout energy booster. Other basic things until you realize that nothing you are doing has helped.
3. You reasearch testosterone boosters. There are a thousand of them out there. Some are much more recommended then others. You learn about thier side effects (which arent that much), how to take them, and you read others logs of how they felt on them. They are pretty mild and could help you break through the tough spot. If they do then great, back to step one, until your next plateau.
4. When test boosters haven't helped, or maybe you are at your 2nd or 3rd plateau you cant start looking into PH's. If you don't need PH's because you can break your plateau natural ways, then that is your best bet. PH's need alot of research done on them before you cycle one. Some are milder then others, but even the mild ones have caused some people issues (luckily not me). You need to research support supps, and PCT. Some designer labs have created total liver killer PH's. They mix methyls which isn't recommeneded, some have upwards of 3 methyls mixed.
This is a very broad path but you will get the idea.
