I will soon be starting a split-protocol. I will replace a portion of my injected T-cyp with daily T-cream. My eventual goal (after some initial trials) is to reduce my total exogenous-T, by titrating down. This should lower my E-2 and my "over-range" Free-T. I've ordered 10% cream in a Topiclick dispenser. Each click will deliver 25mg of testosterone cream. One advantage of using cream is the short half-life. My blood levels should stabilize in just a week or two and I can titrate down and use labs to verify drops in E-2 and Free-T. (
What is the half-life of T-Cream? How long will it take to get stable levels to test?)
Once I achieve an appropriate level for Free-T and DHT, I can stop titrating and just hold that dose for an extended period (3 months, or so) and allow my body to adapt. Then, I can assess how the new protocol makes me feel.
I inject T-cyp on Mondays in the late-afternoon and Friday mornings. The cream will be applied daily with just an early AM dose, but possibly include a PM dose if needed. I'm hoping that having an injected "base" of T-cyp in my system will carry me through the afternoons and evenings without needing an afternoon/evening dose of cream. I know others have tried this approach.
I'd be interested in comments on how well it worked. I'm also interested in what percentage of the total dose ended up being injected vs. applied as cream.
I have a question or 2 about labs. As I titrate down, I will be pulling labs at each new dose to check levels. There are 3 levels I am interested in: E-2, Free-T and DHT. Nelson has made it pretty simple to get these labs with the
Discounted Labs website. My question is about when to have the blood drawn.
With injected testosterone, the obvious choice is at trough, right before the next injected dose. This also might work for a split protocol (injected + transdermal), especially for Free-T and possibly for E-2. However, I see a lot of cream-users on this forum testing at 4-hours after applying cream. This is supposed to catch peak-T and also get a "close-to-peak" reading for DHT. Peak-DHT, according to various posts, happens around 5-8 hours after the application of cream (
Is this correct?).
Here are some options:
Option-1: Get tested 4-5 hours
after applying cream on Mondays and
before the next injected dose of T-cyp.
This would be peak for the cream and near-trough for the T-cyp.
Option-2: Get tested Friday morning before injecting T-cyp
and before applying cream.
This should be the true-trough for both media.
Option-3: Get tested Tuesday morning 3 to 4 hours after applying cream.
This should be near-peak levels for testosterone for both media. (T-cyp should peak about 12 hours after a sub-Q injection. If I apply cream when I wake up (5:30 AM) and test 3-hours later, this would be about 16 hours post T-cyp injection--close enough.
In the interests of science, I'm willing to get 2 blood draws at different times on the same day. This will allow me to monitor DHT at its own peak and to monitor testosterone and E-2 at a different time.
I don't want to go too high on DHT but I do want to see what effect it has at different levels. To some extent, I should be able to moderate DHT by location of applied cream (scrotal vs other places) and total area of skin covered by cream (small area saturates the 5-a Reductase enzyme and limits DHT/large area avoids saturation and increases DHT).
To explore this, my first set of trials will maintain my current total dose of Testosterone (120mg/week), but try different amounts of cream to my scrotum--each with a corresponding reduction in T-cyp for that trial period to maintain 120mg total. Each of these trials will be checked with labs and posted here.
Thanks in advance for any constructive advice. (Note: I'm still working on improving my Serum-Iron and Ferritin--this takes time. Once these have improved, I will be starting with Thyroid therapy.)
