Thread: esters Active half-life

I assume you are trying to say that this is the drug half life? correct?....because there is a difference between a half life and a active life.
Basically a half life is half the dosage after a given time. for example dbol's half life is 6 hours. this basically means that after 6 hours, half of the consumed compound can still be found in your system. So if you take 50mg of dbol in one shot (not recommended)...but in 6 hours you can still find 25mgs in your system.

an active life is the entire time a drug can be traced through drug testing for example.

Lately I have been doing a lot of research on this because I like accurate blood levels and I found a pdf from Pfizer on their Test Cyp which says the half life is 8 days and Heavyiron posted blood levels on a graph which appears to be around a 5 day half life.

Test Suspension is king but nobody wants to be a pin cushion so everyone turns to esters. Let's compare Test Suspension to Pfizers Test Cyp with an 8 day half life. If we wanted to match 100mg ED of Test Suspension with Test Cyp we would have to multiply 100mg times 8 and then times 2, so 1600mg. Maybe front loading makes a whole lot of sense. 1600mg is 800mg in 8 days which means it is released at a rate of 100mg ED. Then you only need another 800mg to maintain the 1600mg esterified blood level.

Now try applying that theory to Sustanon and it gets crazy, but let's use the half lifes above and break it down into the most logical dosing. I don't mean the 15-18 day half life listed, each individual one: Propionate 30mg 4.5 days Phenylpropionate 60mg 4.5 days Isocaproate 60mg 9 days and Decanoate 100mg 15 days. As you can see Prop and Phenylprop are pretty much the same thing so it's like 90mg of prop which everyone takes EOD. so in 4.5 days you used 45mg or 10mg/day, the Iso is about 3.3mg/day and the Deca coincidentally is about 3.3mg/day, altogether only 16.6mg/day for only 4.5 days! So to get closed to 100mg E4.5D you would need 6ml day one and 3ml every 4.5 days of Sustanon.

I just switched from Sustanon to Cypionate and wasn't happy with the highs and lows on Sust and wanted to get to the bottom of it and this is it. I just did 1500mg of Cyp and plan on another 750mg in 8 days. Hoping this feels more like Test Suspension ED now.

Just wondering if anyone has experience coughing spasms while injecting cyp? I never had Tren cough so I don't know if my Cyp might really be tren.

Hmmm, never had coughing with any aas injections so I'm not sure if it's rare, underreported or if I'm just an exception to a common occurrence.

I think test E & C the ester last up to 20 days in your blood, making less injections which makes it a great test.

i've never heard of anybody having a cough from cyp

I have had the cough once lasted about 10 miniutes! Was not good! However, I also stacked with Deca so not sure which it was.

Whenever I knick a vein, I cough a lot.
