Total / Free test: test c vs test e

[Dumbbell2008]

Has anyone ever seen different numbers on total/free test using test c vs test e?

I got bloods back on both, Test E was much higher than Test C at the same dose/injection frequency. of course it also could be that the Test E is maybe overdosed, or Test C under dosed...etc. but I was just curious to see if anyone has had a similar experience.

Could be dose differences, could be minor dirlfferences in ester weight vs active hormone, could be just time of day you took the test vs last pin. Million factors at play here- its anyone's guess.

What were the levels of both tests and what was the scale used? And was it the same lab with the same range. Range makes a big difference as to what the result will be. Depending if i send my sample to LabCorp or Quest i can get a 200 point difference on the same blood sample as their scale is not the same. Plus there is the margin for error too.

Same lab, all tests done at roughly the same time in the morning. Been using the same injection frequency and the same sites.


October 2024 75 mg of test E per day: total was 3703 and free was 1392
February 2025 75 mg of test C per day: total was 2527 and free was 876.

I had bloods come in today, so while I was looking through the results, i went back and looked at my previous results, i noticed the difference between these two.

If I’m not mistaken this is what Kurt Havens saying for quite some time now. For the record, I haven’t dived into this but in simple words he claims that with test e you get higher peak compared to test c and this is simply due to the ester. He’s doing a research now and sometime eventually it will be published. Same goes for deca vs npp.

It’s genetic. I heard the same info, but my test cyp blood levels were identical… and Cyp gives me zero PIP. I haven’t been able to use enanthate for years, regardless of brand.

Had the highest serum I’ve ever had while on cyp as well.

Something to do with your ability to metabolize the ester.

Also, I’d test after a good 2-3 months of steady injection frequency. Cyp may take longer for blood levels to rise.

Looking at my last 2 blood tests from the same lab and same dose for my TRT on 15mg/day of TC i am usually in the low 800 range. But on the last test same dose same lab same range it came back at just over 1200. So either something was going on different with me or the lab had an error. Things happen. I don't get excited about any 1 test.

Did you inject the same number of days prior to each test?

If the injections aren’t ED or EOD, you’ll have slightly different blood levels depending on the peak and trough timing.

Shit man, even things like doing squats after pinning in glutes/quads for example can affect serum levels.

We are all kinda just throwing shit at the wall on this one. It could be one factor, or 20

I do daily injections, have for about 7 years and injections and testing were done the same as usual. There is some variation in peak and trough even with daily injections

I’m jealous of these numbers, holy cow! Maybe that’s the norm for guys? Idk, mine never seem to get that high though. I also don’t do daily injections though.. feel like that plays a part? I’d run out of places to go with it… unless you’re doing sub q?

yea damn, those levels are roughly the same levels i get but on 900mg per week not 75mg per day.

I did bloodwork on 875 test and gotten just 1990 ng/dl wich seems very low. However my free test is 240pg/ml, and the top of the reference range is 22pg/ml, so over 10x the top range nember. This would be more in line with the total test i was taking.

Does this make any sense at all?

First thought when i saw the 1990 was that the test is underdosed, but seeing over 10x the value for free test, i'm kinda lost here.

Am I the only one that doesn't feel great on Test E? I switched from Test cyp to Test E and I just feel "off" on it. I also retain a lot of water with it.

My buddy is same way. Had "test flu" -like symptoms with E. Has been running C for years

Glad to know I'm not the only one. Im definitely switching back to Cyp.

I gave him a couple pins to try of test U and he has no issues with that as well. Not sure if you have ever tried it, but undecanoate has been amazing for simple trt. 1 shot every 10 days for me

he did talk about this and even though cyp doesn't build on itself like other strains specifically Enanthate, from just experiences I would agree with others that its also very much based on genes. I ran test E for years thinking it was best for me, went to sust and that fucked me up changed to cyp and it was a big difference. BUT I will say because they are so much alike in build structure and half life if they can still be interchanged if like one is harder or easier to get or in a pinch.
