Testosterone Level Tanking
ad
I'm coming off 350mg testosterone enanthate. My last pin was Wednesday, Feb. 18. I am having to come off to go to a TRT clinic and get an actual prescription. I am not going to do any PCT or hCG as I am going to return to TRT after my levels have tanked. How long should I wait to go to the clinic to get my bloodwork done to ensure my testosterone levels have tanked after the exogenous test has fully left my system? I'm looking to wait until my test levels are around 300 ng/dL or lower. Any advice on how long this will take will be very helpful. Thanks!

2 weeks will be plenty. Depending on the TRT clinic you go to it should be very quick, I know some that will take labs from anywhere and give you a script with no contract. I'd advise to stay away from places like Hone. If you go to a GP, expect a run around and poor dosing/scheduling protocols
Do you remember about roughly how long you waited? I think I'm gonna get my blood tested through goodlabs next Friday (9 days from last injection). See where I'm at then and if low enough, go to the clinic the following week
Any chance you know your SHBG? Im low, 15, and clear pretty quick. My half life is functionally 4-5 days.
A few years ago I needed and script and did what you did. I knew I was ready when I was super grouchy, my wife was about to toss me, and I was ready to crash out at any minute. When I got tested, I was like 125. I can't describe how it felt, but if you wait long enough, you'll know what I mean.
Figure an average half life of 8 or so days. So in a week you’ll still have 175mg of the hormone in your bloodstream, another week there’ll be 87.5mg in your system, now you’re at TRT levels. Figure 5 half lives for a drug to be basically eliminated. Now for your levels to be “crashed” like 80 year old woman crashed? Wait a month and a half or even two. You’ll be there.
The Half Life of Testosterone Enanthate is 4 days mate.

You’re going to find different answers for this, I tend to go with NCBI for most of my questions regarding researched findings.
Yep, to me it defo feels more like 4 days than 8 though. If it were 8 then guys wouldn't feel so crappy only doing 1 injection per week for TRT is my thought.
Key Pharmacokinetic Details:
Half-life: Generally cited as 7–9 days, though some data indicates 4.5–5 days.
Peak Time: Levels peak around 0.5 to 5 days after injection.
Duration: Levels typically return to baseline after 2–3 weeks.
1.5-2 months? This is gonna be a good next couple months! --
Yeah buddy, it takes a little while for the long esters to clear. People are different though, some could be pretty low n a month, but if you’re looking for the worst numbers possible you’ll need to wait. Everyone is different though, you could be one of the lucky ones and don’t get completely shut down, then your test comes back within acceptable range… I don’t think the clinics care though, they’ll throw 200mg a week at everyone and call it a day.
