Defy. I did research for years before deciding, and I called all of the big name ones and felt them out. There are ways to do Defy cheaper. Use a referral code online and save on initial consult, get initial bloodwork from Marek and save, although it has standard e2, not sensitive in it and Defy has the lowest price on sensitive e2. They will also write an RX to get bloods through your insurance if it will pay for it.
If you're in Fl they will call in 6 months of t to local pharmacy for a $30 fee (this $30 fee will include calling in other meds that you can get cheaper than buying through them, such as tadalafil, sildenafil, anastrozole etc) and you can use goodrx. I only pay $43 for test. If you're not in Fl they can still call in non controlled substances in for $30. If you're first responder, military or LEO you can get 10% off of most things in their online store, including compounded t, anavar, nandrolone etc but no discounts on bloodwork or peptides. Compounded t is $130 plus shipping before discount through either Empower or Hallandale.
They offer test, anavar, nandrolone and winstrol, Sermorelin and Ipamorelin mixed every different way, then if you can't get meds called in they sell all kinds of shit, tadalafil, sildenafil, prenenalone, progesterone, minoxidil, finasteride, latanoprost, etc etc.
Their service is great, they are open late, only require two consults a year once you're setup at $90 each and take a lot of time on the phone with you going over things. The only complaint is processing time and shipping time from their compounding pharmacies.
The Restore Clinic is another good option people don't talk about, but they don't service as many states
