Lower than expected T levels using Test Decanoate?

[RockyP]

I’ve seen a few posts here and elsewhere of folks using accurately dosed / tested Test Decanoate and coming back with what appear to be lower than expected test levels on bloodwork. It’s a small number of people and could be due to a million idiosyncrasies but wanted to ask around if anyone has seen this using a comparable dose of test Decanoate as compared to your cyp, enan, or sustanon?? I understand on paper it doesn’t make sense other than adjusting for larger ester weight, but still curious about others’ experiences.

I don't know about the others, but I was quite surprised with how comparable T numbers I got on TU (udecanoate) versus TC/TE (cypionate & enanthate) even if on paper there was quite a bit of a difference.

So your Test U levels were similar to Test E / C at the same dosage (which they should be)?

gotta discount for ester weight.
also, the time it takes until levels are stable is a bit longer on test D

That could be why folks are pulling low levels. 4 to 5 weeks really isn't enough for Test decanoate. More like 8 would be best to see steady state levels.

isnt halflife 7 days? thats x5 so 35 days until full saturation, or 6 weeks?

im on week 3 of that ester, will be doin bloodwork next week but its pountless to measure rn and by the time it will saturate, its likely i will do small bump up...

but so far i feel fine. 200mg every 7 days.

are you guys making up for the increased ester weight when you compare decanoate and undecanoate to different esters?

yes. definitely always do that.

The range i saw for TD was 7-12 days and I always use the larger number to build in margin for error.

SHBG will also have a factor on total testosterone, there was a thread on it here. Will have to dig it out

ive found this around here
also, source ive bought it from mentioned 7 days. so im goin by those 2.

at the end of the day it doesnt really matter for me, 1/2 volume of oil needed, once per week frequency. 1g blast could be done with 2ml. just wonderfull.

Nebido has ~158mg/ml test, E and Cyp ~176mg/ml (250) excl. ester weight.
So that could be why U is tested lower.

Not informed about Deca ester in T

~63% actual test, so 315mg/500mg are actual test

Shit, I should have made myself more clear here. What I mean on paper is actually an ester weight, since TU is quite heavy ester it has less actual Testosterone that matters.

So for example, say I take 350mg of TU (undecanoate) it is equivalent to something like 316mg of TC (cypionate). Adjusted. Something like ~63% vs ~69%.

Is this home-brew Test D?

The raws I have and have seen around right before the shortage tested around 89%. If you brewed with those, there might be lower test in your vial than you think.

those have pretty nasty PIP, would not recommend

I think it has to do with how fast your body breaks the ester chain itself

Those are my results

Test e 25mg daily - 88nnmol
Test c 25mg daily - 55nnmol
Test p 25mg daily - 98nnmol
Sustanon 25mg daily - 110nnmol
My SHBG was between 21-36 during those tests
Also I gave enough time for each ester to clear
Blood work always in the morning fasted before Injection

Please note I used Pharma grade gear.
