- How long have you been lifting?
- How is your diet?
- What supplements do you use?
- What is your height and weight?
- Have you hit a plateau?
- Do you lift heavy and consistently?
Some of the answers may help you to answer your question. I never touched any hormonal substances until I was already strong, lifting heavy consistently and had my diet down. If you drink or smoke, don't even bother with a PH or gear. If you just want to look good in a tank, do your research and don't mess with the harsh PHs. If you are looking to compete, then you will need stronger PHs down the road. If you aren't dedicated, I can almost tell you for sure, you will keep NO gains from a PH cycle.
If you aren't ready to that dedicated, stay away from PHs as they can seriously damage your health and do have real life side effects!
You should NOT touch any PHs till the age of 25 years of age. IMO, 25 is a ideal age to wait.
DO TONS TONS OF RESEARCH FIRST!!!!
Just wait and good luck!
