ESTER CHEAT SHEET

[88general88]

Thought I would drop this for anyone who isn't quite familiar with the different esters and their half life's. I know everyone's body metabolizes things differently but for the most part these are on point.

Shouldn't Cypionate have a sightly longer half-life than Enanthate? As in the below:

Now we just need another chart comparing how the different carrier oils effect drug release. MCT vs castor and so on

A big thanks!

I have heard it both ways so am actually confused on this as well

pharma is primarily castor and GSO in the US right? Surely there would be some studies comparing the two

I believe compounding pharmacies use GSO the most, but for off the shelf products from the big pharma guys I'm not sure. The last time I saw a phizer test cyp come out of CVS it was cottonseed oil.

i had some test c in cottonseed oil from us pharm

For me From normal pharmacy it was usually cottonseed and from a TRT mill compounding pharmacy it was usually GSO

Also, I’ve seen multiple charts all with different days listed.

I just do it the bro way.
Cyp once a week min
Enth E4d min
Prop daily
Ace daily
Phenyl EOD min

I posted some studies comparing carrier oils here a long time ago.

Can't find rn but my take home message was this: no big difference over the longer-term.

People choose carrier oils for reasons other than drug release/pharmacokinetics. Personal preference, ease of injecting, PIP, etc.

Always useful as a reference. Thanks for sharing

we are back to the old charts..... Last time I checked everyone was in agreement Cypionate has a 3.5 day half life same goes for the other esters ,deca is 7 days, ace/prop is about 1 day...
this ofcourse in the context of the most popular oil used today...MCT... hence the most relevant for most guys ...

 

[Spaceman Spiff]

I feel like this chart isnt right...

It isn't. Those are clearance times not half lives

 

[Spaceman Spiff]

It isn't. Those are clearance times not half lives

even then, Test U half life is 16.5? lol

 

[narta]

even then, Test U half life is 16.5? lol

That is correct. It doesn't take into account the carrier oil though.

 

[lukiss96]

This is not accurate. Cypionate half life is shorter than enanthate lol, people this is 2024 you should know better and if not just google and prove yourself wrong. Also TU hl is wildly different depending on oil.

 

[Benf15harp]

This is pretty bad.

Testosterone subQ absorptions rate based on carrier oil

Personally I find that different carrier oils absorb at different rates and have different "half-lives" if you will depending on them. For me, MCT oil seems to absorb muuuuuch slower than grapeseed oil for instance. Because I inject subQ, I can physically notice the difference in absorption...
