Hi sakes,
Your very close to being classified legally as an adult, however tampering with something that can affect testosterone levels at an early age is not a good idea. Especially with the test levels that are naturally flowing in your body.
Your at an age where if you meddle with anything inside in any way can have negative ramifications that can show up in time. Right now the best thing is to eat and train hard. When you are at the legal age to make your own decisions, Mass FX Max can be a phenomenal addition to your training.
If you have any questions, scroll down on the main board to our company subforum or shoot a PM.
Good Luck!
