Test Esters

[avega602]

Can anyone direct me to a thread that can shed more light on the different testosterone esters (benefits/downsides)

Prop is pinned eod
Phenly prop eod
Cyp and enanth are every 3 days
I never used prop or phenotypic prop
Cyp holds less water in my body.
Really depends on how often u want to pin

Testosterone esters and their half lives consist of the following:

Cyp 10-12 days
Enan 9-11 days
Prop 2-3.5 days
Suspension 1 day or less
Phenylprop 3.5-4.5 days
Isoc 8-9 days
Decanoate 12-15 days
Undecanoate 14-16.5 days

Google will be your friend with this one or just look at the above posters.

Have a read about ester weight also as this effects the dose of the compound you get depending the attached ester.

How one "ester" effects user differently

Recently I've noticed the topic about the usage of 1 particular ester yielding different results in users..
Or, others claiming one ester to be Superior to the next..This is all individual based on ones static system of checks/loops,no two individuals are the same..
This is why people argue that cypionate is much more potent than enanthate,
as this is a fragile argument at best and makes little sense,
as your muscles/receptors are only recognizing free bihormone no matter what the ester that was utilized to deploy the parenting hormone!

These are great questions & a worthwhile topic, as there's some real truth behind this;

Let's begin with the expression of a single hormones yielding an opposite effect - rather than a positive "smooth" response to the hormone as some individuals claim/experience..
An appropriate example to begin with would be that of an alcoholic...

Why? Because of Genetics, I'll explain!

Everyone posses different gene expression,with enzymes,protein bonds,and so on..
(Enzymes are known to catalyze more then 5k biochemical types)..
Yet our bodies posses inhibitors and activator molecules that can greatly effect the activity,
by increasing or decreasing hormonal actives..
Now, that of an acholohic,it's a genetic predisposition (same applies for particular endocrines with sensitive users concerning AAS) in which one posses a group of particular enzymes that metabolize alcohol much differently compared to other individuals,
thus the effects will be much greater, and more detrimental in some individuals over the next..(Different metabolization)

Now, let's compare this to the hormones!

(Example) Testosterone can have 3 roles
1) Being testosterone as it's primary function..
2) Converting into DHT (dihydrotestosterone: a more potent metabolite/androgen)..
3) Converting into estrogen Here you see this effect differs greatly by individual instances, as genetics, age or even ethnicity (in some cases),
or even sex may be a factor, whether one has a greater presence of aromatase enzymes, or even a deficiency..
Hormones/esters have various biosynthetic pathways occurring in the endorcrine,
some either or before reaching their target tissue(to control plasma levels or active compounds),
or at times after termination of their actions (inactivation and elimination)..
However many of hormones and esters are metabolized within their target tissue,
in which a complex interplay between activation and inactivation mechanisms serve to regulate the specificity and the amplitude of the hormonal response..

This is why "singular ester" hormone treatment is NOT designed as a one size fits all therapy...
Just an FYI: There's two main types of enzymes that act in the cleaving process of the ester in which activate the hormone...
These 2 particular "Enzymes" are esterases & hydrolysate.. These come along and cleave pieces of the ester off the hormone,
thereby releasing the active chemical (parenting steroid hormone) and allowing it to do its job (ultimately muscle building/tissue via protein synthesis, positive nitrogen balance and so on )...
Now in the bloodstream which testosterone and blood born nutrients and substances circulate is recognized as the "medium".
These enzymes circulate in the medium and directly affect the release of "active" hormone in the bloodstream by ester cleavage, thus exerting different expression per individuals, trigger a chute of cellular interaction at receptor sites that will differ from one to the next..

People need to remember that hormones are "chemical messengers" that rely messages to cells that display specific receptors for each hormone and respond to the signaling..Depending on the ester and the individuals metabolization ratio the hormone can/may make changes directly to a cell, by changing the genes that are activated, or by making changes indirectly to a cell by stimulating other signaling pathways inside a specific cell group that is effected and effect other processes, thus this can "initiate" an intracellular cascade of events..

This is why the "same/singular hormone ester" effects people differently, because there's numerous ways a hormone can yield different effects..So, depending on which transcription factors are present different genes will be transcribed in response...Thereby the reason some individuals tend to bloat and others do NOT, as some can run 250mgs of Test and begin to see signs of fluid retention or edema exert in the circular system, or particular regions of the body..Yet, there's individuals that can utilize 1000mgs of Test and remain dry..Of course diet permitting.. (but this article's about biosynthesis, and not diet)

Here's a basic read on how one ester can have MORE sides ( i.e. Acne) compared to an other!
(This also applies to other side effects as well, but that's a different topic)

Acne can be induced through many courses of actions, however this is simply covering the on-set by way of esters for different reasons (not estrogen, Testosterone, 19-nors, DHT etc etc).
Some uses/subjects make all sorts of claims and to a degree everyone has a valid point on or possible explanation that pertains to their particular instance, but the truth is everyone SERIOUSLY responds differently , not everyone's endocrine system will respond the same when it concerns exogenous or endogenous hormones, some people may possess more or less of "targeting cells" of "enzymes" in which these cells bear receptors, and these sites can/may be more hypersensitive or actual desensitized by way of "genetics" or other transcelluar chemical messengers..
These effects can greatly influence a slew of side effects, i.e. the topic at hand "acne by different esters"..
Esters can effect differnt mechinisms over the next, like stated above by way of activation through different transcellular groups, increasing different hormonal out-puts, sections and so on..

Take home note: Please read!
For myself, Nandrolone Phenypropionate doesn't suggest a greater aggressive display or influenced onset of acne compared to it's counter part "Decanoate"...(Decanoate triggers a stronger andmore aggressive state of acne for myself, and many others, compared to NPP, same applies for other hormones with different esterfication!
Why is that? believe it or not besides the hormone , the ester alone plays a pivotal role as esters all possess a different molecular weight, with this said the presence of fatty acids may vary, and this alone has a unique influence on sebaceous lipids which is directly associated specific accumulation of squalene and the presence of fatty acids and lipids yielding a manifestations in increase of sebum..
So, can one particular hormone be more responsible for sebum production verse an other? This will be individually based..
How about the ester, does this matter although it's still the same hormone? Yes, the ester can have direct and indirect effects on different people, depending on the amount of presence enzymes, sensitivity, receptors and so on.. Ester effects are truly miltifactorial by way of activating, deactivating of different cellular groups, especially - lipids as some may be reduced in some subjects such as free fatty acids or in contrast, there could be a greater influx with triglycerides and wax/cholesterol esters could be increased inducing acne, especially in those who are already sensitive and prone/predisposed..

Aside from antiestrogens, acne medication, antibiotics, and other acne treatment protocols, it may be wise for some people to use more liver support,
take antioxidant supplements, or even consider use Tad-600.. Just some food for thought.
