Questions

Does a listing mean the clinic is good?

No. It means a public registry lists the business under a relevant specialty, or its name says it treats hormones. Quality, pricing, and whether they run proper workups (labs twice, morning, before any prescription) is what the member reports and the evidence-graded articles are for.

What should a legitimate program do first?

Two morning total-testosterone draws, SHBG, LH/FSH, hematocrit, PSA where indicated, and a conversation about fertility before any prescription. A clinic that prescribes on one afternoon draw is a warning sign.
