Spectrum has you fill out and online list of questions and you just tell them what they want to hear,ex: yes I am tired all the time, no I don't sleep well, yes my body fat is up , my sex drive is down etc........They will send you a package with everything you need to get the blood work done vials paper work all,they will also find the nearest Concentra medical facility to your home and set you an appointment they will then tell you not to discuss your reason for the blood work with anyone at concentra (for obvious reasons), just tell them it is for a wellness checkup.Concentra FED-EX's the labs, BOOM your done.Just wait on a call with your results.They did ask me if I had ever used hormones before and NO is the answer.They do test everything from GH, cholesterol, thyroid etc......
