You are too young to start using these drugs. You still have enough hormones secreted for effective training, so the best option for you is not to take anything. But if we are talking about what is safer, then growth hormone will certainly be less dangerous for you at the age of 25 (if you do not take huge doses). Just at the age of less than 25 years, the effectiveness of taking this drug will not be too high, so not all of its positive effects will help you. You can try to consult the Turkish company pharmaHGH about the use of HGH, you will be able to explain the need for the use of growth hormones.
