What if I can’t do a ProLon cycle exactly one month apart?
Participants in our clinical trial all maintained as close to 25 days from the completion of one cycle to the beginning of the next, so we cannot say exactly what impact delaying or starting cycles early might have. In general, the closer you can keep to the clinical trial distance timing, the more likely you are to achieve similar results. If you want to start the cycle more than 5-10 days early or more than 5-10 days late, we suggest discussing this with your healthcare provider Read more...
