too many variables from individuals to say definitely no way you will recover or not. In general, the longer a person is on, the longer the recover time and the greater use hcg can be. Will you recover after a 20 week cycle without using hcg? Probably, but will it be harder and take longer? Again probably. I dont know if this question can be answered any shorter or simply than this. Now the question you should be asking yourself is, are the gains in weeks 10-24 worth the longer and more difficult pct? Only you can answer that for yourself. Also take into account that often, but not all times, there is a point of diminishing returns on cycle length, where gains slow and dosages need to be increased to get them going again, which also will make recovery more difficult.
