Certain level of development that exceeds your natural level, can be achieved by using relatively modest doses of drugs, but on condition that you properly train, eat and sleep.
For the average guy with average growth of 175 cm, with an average bone structure and genetically typical recovery and power indices (the weight of the dry weight 85-88kg, bench press 125-135kg, a full squat 170-180kg, and about 225kg deadlift).
In the future you will need much more doses of drugs, to observe a continuous growth. Increasing the dose is not proportional to increasing body weight. For example, many may increase the weight of 4-5kg with at least 250mg of testosterone per week. To increase the mass by 10% would require to increase the dose much higher than 10%. Let's say 15-20 kg require a large dose.
Number of drug used depends on how close or far you are from a natural maximum.
Large doses of drugs used to lower their own body weight will certainly accelerated growth, but at great cost of money and troubles … "expedited" does not always mean fast.
