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
