I'll give you a few guidelines to help you make your decision, whether considering an Online, or more traditional medical practice:
1). Is there a real doctor actually going over your Medical History and making the decisions? Or is it just a salesman sitting on the phone all day trying to make money by selling drugs. Most Internet services have a physician involved in name only, and the actual "treatment" decisions are made by someone with no actual training--or credentialing.
It's not appropriate--or legal--to have your treatment directed by a Pharmacist, either. The two examples provided here constitute Practicing Medicine Without a License.
2). Is a true physical exam required? 10% of men will develop prostate cancer. You do not want to be the guy who does while on unmonitored TRT.
3). Is proper initial labwork done? I have posted here an appropriate panel, meant to also look for more ominous causes of symptoms. Or is it just the minimal testing, used to try to justify selling you testosterone?
4). Are proper follow-up tests conducted? This is ESSENTIAL to safe and appropriate TRT. For instance, estrogen MUST be followed. Refer to the report I stickied here to learn why. Most of these Online clinics do not want to be bothered by actually doing appropriate follow-up work with their patients--it gets in the way of making sales.
5). Are they selling "programs"? If so, go somewhere else. How is the doctor supposed to know how much you will need until he/she actually tests you? That would be like having a doctor walk through a Waiting Room of brand-new patients, and randomly assigning them drugs and dosages before even seeing them.
6). What are their actual TRT protocols? Do they just sell everyone Arimidex without testing for estrogens first and thus demonstrating need? Most do so they can make more money. Do they "cycle" the TRT? This concept has been largely abandoned by everyone in the industry who knows what they are doing, and would serve as evidence that the clinic does not care to offer the best treatment protocols.
7). Overall, check out the doctor who is administering your treatment. You would for any other medical reason, right? Is this individual associated with one of the mainstream Anti-Aging Medicine professional societies? What exactly is his/her training in this field? Imagine that you are actually receiving chemotherapy for cancer--the consequences may be as severe.
The bottom line is a simple question: are they in it for the health and well-being of their patients, or the size of their own bank account? Make sure you are being cared for by someone who meant it when they took their Oath as a Physician.
I hope this helps.
