Test Cream Labs Timing

[MJ65]

How soon after non-scrotal test cream application should I have labs drawn to measure testosterone levels? My understanding was 3-4 hours after application for blood draw.
Thanks in advance for any feedback

You should test 2-4 hours after applying topicals.

"Should" for what? What's your objective? No one can give an answer in a vaccum.

2-4 hours post application will give you peak levels. We always test trough levels for injections but for some reason everyone has passively agreed to test peak levels on the creams, and I've never seen even an attempt at an explanation for it.

I like to test both peak and trough regardless of protocol. I want to know the range I'm operating with. Especially with creams where if you're applying once/day, your peak could be 1000+ ng/dL and your trough 350ng/dL 24 hours later

When I first started Jatenzo, my doctor had me run labs at trough or 12 hours later before my morning dosage. The problem I ran into was my levels didn't show an increase, 289 ng/dL everytime on 158, 198 and 237 mg.

Once I started running labs at 4 hours, which is what the makers of Jatenzo say to do, I would get 715 ng/dL. It's not like we test at night time when testing for natural T levels, because you'll always get a low value.

Due to the short half-life of topicals and oral T, you must test at the 2-4 hour mark.

I haven’t done bloodwork since mid January of this year (01/15/2022) and I cannot get a straight answer for trough while on Atrevis Hydrogel based cream, so at what point should trough be measured? I apply each morning only.

How do you feel on it ?

I have tested both trough levels and 3 hours after application levels. It was interesting to see the peak, but I usually test at trough, first thing in the morning and before I apply the cream.

So far, pretty good, but I’m open to whatever works,

Since you are continuing with the Atrevis base I assume no skin irritation for you? I developed some annoying bumps and itchiness and had to discontinue (scrotum itching was the worst!)

No problem with it here.
