    Another Great Experience with Defy

    I had my initial consult with Dr. Saya last week, and I'm pretty darn impressed. The wait for the initial consult was definitively worth it. Dr. Saya was very knowledgeable about all the related blood work findings, and went through each area to make sure I understood any concerns he had. The...

    All things Male Dr Crisler reviews?

    I asked this too for a script, and I was told they only do that for folks who are in FL. If you are with Defy and outside of FL, you have to go through the compounding pharmacy. I would have preferred to have the script filled locally because like you said it's cheaper, but I'll pay the higher...

    Type of Oil and Can you Mix?

    This may seem like a silly question, and I couldn't find an answer specifically on this exact topic. I'm finishing up my current RX from my Endo which is Cypionate and it has Cottonseed Oil. I just got my RX from Hallandale (through Defy), and I see it has Grapeseed Oil. If I'm finishing my...

    Splitting Dose

    No, just the T. That may change in two weeks when I meet with Defy though.

    Splitting Dose

    Specific Protocol for Needle Length IM

    Thanks Sean. I've never done the quads, I've just had the glutes and delts done. I do have some slight soreness on the delts, but it's more from hey you just got pinned, like a flue shot type. I'm usually in the midst of a workout so it ends up going away pretty quickly. I'm looking at...

    Specific Protocol for Needle Length IM

    Thanks Vince. I figured 5/8 would work. Nelson has much bigger arms than I do, so I wasn't sure how that would play into it.

    Specific Protocol for Needle Length IM

    Is there a specific protocol for needle length when doing IM injections? I've seen things like it's based on the amount of bodyfat etc, but I haven't found any specific information. I know Nelson does 27g 1/2" in the delts. I've been having someone else do them for me in the delts using 25 g...

Free Testosterone

The biologically active form of testosterone not bound to proteins. Directly available for cellular uptake and biological effects.
