There is a lot of information on the internet stating that one needs to be on growth hormone for at least 6 - 9 months to begin seeing the effects of HGH. The truth is this is such an important hormone to our bodies highly responsible for cellular regeneration and cellular metabolism that from the first dosage your body will begin to change.
The effects of real HGH can be felt in the first week of using it. When taking Biotropin HGH you are adding on top - regardless of how much amount of HGH your body is currently producing. This will cause an instant amplification of cellular regeneration and increased protein synthesis. The skin, hair, nails, eyes, muscles and joints are all proteins and, as a result, there will be an increase in the quality of all these physical factors. Regarding the time it takes for one to see a drastic change in body composition ie muscle mass and fat loss - it all depends on your starting base. If you have been training consistently for some time, you will notice the changes to your body fast. However, if you are a beginner on your fitness journey and only beginning to enter resistance training or athletic training, then your results will take longer because you haven’t previously activated the androgen receptors nor developed lean muscle tissue or increased your metabolism via physical training.
As a general rule, however, results will be strongly noticed within 4 weeks for a trained person and around 8 - 10 weeks for someone who does not train often or is just beginning.
