    160mg/40mg Testosterone Cypionate / Propionate Blend by Empower?

    You have an interesting protocol 10mg-12mg subq daily. Just curious if you have drawn labs during this protocol to see how testosterone, DHT, and E2 levels maintain? If you metabolize propionate consistent with known pharmacokinetics then it could be likely that your level has a nice consistent...

    160mg/40mg Testosterone Cypionate / Propionate Blend by Empower?

    Testosterone propionate is definitely not for everyone, however, there are certain men who do benefit from including the ester in their therapy. Propionate needs to be injected more frequently than cypionate, roughly every 2-3 days if used as a monotherapy to keep serum testosterone stable. For...

    Spring 2018 Dr Lipshultz will be opening a concierge men's health and primary care clinic in Houston. Although it will be mostly cash pay, there will not be a long wait time to see him as with Baylor. In addition, he will not be as limited by the academic institution and will provide a more...

    Sildenafil Slow Release (SR) Empower?

    No problem Jake, hope I was able to help. Do not hesitate to post any more questions as this can also help others who might encounter the same issue. Empower will be launching their ODT tablets in roughly two weeks. In the meantime, ask Defy to order you sildenafil 100mg troches which can be...

    Sildenafil Slow Release (SR) Empower?

    Sustained release PDE-5 capsules are still commonly prescribed to be taken 60 min prior to sex. The reason that compounding pharmacies compound PDE-5 inhibitor capsules as a sustained release is because they cannot make a tablet or capsule that is too close to the commercial equivalent. In...

    Low Testosterone and Chronic Prostatitis/Chronic Pelvic Pain Syndrome

    Chronic pelvic pain in men is more prevalent than I thought and often misdiagnosed. One potential cause that is often overlooked is referred pain from lower back injury/disc. I have seen cases where men have various pain/sensation throughout the pelvic/genitals, where they were convinced...

    Extensive blood work results. Prolactin, DHT, Estradiol, Luteinizing way off?

    I agree with Dr Saya regarding the unfortunate limitations that the insurance model imposes on our healthcare system. I work with a few well known urologists who try hard to be progressive in their TRT protocols, however since they must take insurance as they are tied to academic/hospital...

    Aps pharmacy new hcg formula?

    Compounded Drug Products ThatAre Essentially Copies of aCommercially Available Drug is draft guidance, not regulation (yet). In addition, this issue appears to be isolated to APS pharmacy as I work with multiple 503a and 503b pharmacies that do not have to change their formulary. If you closely...

    Crashing or something else? Need some guidence.

    Empower for sure does potency, sterility, and endotoxin testing on every injectable batch before becoming available for dispensing to patients. It is required in both state and federal law for them to do so, and because I work with them I can confirm this is done. You are allowed to request a...

    Hallandale Pharmacy

    Your fears regarding "underdosed" bottles can be at ease due to the fact that no pharmacy, 503A or 503B, can dispense any sterile injectable without first passing third party analytical testing to confirm sterility, potency, and endotoxins. The test must pass FDA standards before being released...

    Bunk Meds from Hallandale

    The first course of action should be to request the analytical report from the pharmacy, which the clinic can do for you. Any pharmacy who compounds or manufactures a sterile medication must send each batch to a third party analytical lab to test for potency, sterility, and endotoxins before...

    Anyone else using Perrigo from Wallgreens?

    APS is also in the process of changing over. Their last visit was in specific reference to their compounded testosterone cypionate.

    Anyone else using Perrigo from Wallgreens?

    You will find that almost all compounding pharmacies will be dispensing two 5ml bottles rather than 10ml of testosterone cypionate. The reason for this is because of the FDA draft guidance "Compounded Drug Products That Are Essentially Copies of a Commercially Available Drug Product Under...

    Freeze Testosterone and HCG

    It is not recommended to pre-load syringes for storage. To preserve potency and sterility during storage the syringe needs to be loaded in a sterile environment, such as under a hood. Contamination occurs when you are transferring within a non-sterile environment which then reduces the...

Dihydrotestosterone is a potent androgen derived from testosterone. Affects hair growth, prostate health, and masculinization effects.

Free Testosterone

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