Documentation on Esters and Serum Levels?

**rmbX66t1** · 05-09-2013, 03:17 PM

I'm trying to work on a spreadsheet in Excel to monitor my serum levels based on injection frequencies. I am curious if there is any documentation on the elevation, peak, and drop of serum levels based upon the ester half lives of various compounds.

Thanks in advance to any help that can be provided; I am sure there is some sort of formula existing, or at the very least something I can conjure up with more information on the rates of rise and decline.

I'm sure this would depend on exactly which brand was used
The amount etc
And would also have to have bloods drawn at very regular intervals
I don't think its something you can just knock up on a computer

I have no formal medical education; however, give or take any variances in the body's ability to absorb the compounds, wouldn't the half life dictate the release of the compound from the ester? I don't think brand would have much to do with it, and any variance that exists would be within the confines of the individual's body, as well as the efficiency of the injection (deep in the muscle vs. subQ).

Assuming the standard vacuum in a case, wouldn't a proportionate percentage of the compound be released as the ester is metabolized at the rate dictated by the said ester?

This is my interpretation, but perhaps I am incorrect.

He's but you mentioned serum levels
This would depend on brand etc due to exact amount of powder used in each vial

Some ugl are underdosed some overdosed pharma grade would be best for any experience

I'm not sure you're understanding my question or if I just worded it poorly. I understand that the dosage and ester will cause a variance. However, I assume it is proportionate. If the half-life causes (hypothetically speaking) a 50% release, on every X number of days, then it would be proportionate - meaning the dose is not of substance.

i.e.: Test E half life is 14 days, so every 14 days 50% of the existing compound is released;
Test E, 250mg/mL, 70% of weight is in compound, 1mL injection:

• Day 14: 87.500mg released,
• Day 28: 43.750mg released,
• Day 42: 21.875mg released, etc.

Now, I understand, this is not how it functions; however, what I am trying to establish is the pattern in which it does function. So that I can calculate how much active compound is in my body.

Am I making sense? Lol.

*bump*

Has anyone got any insight into this? I recall seeing a thread, possibly a year ago, that broke down the numbers in the manner I am referring to. It seems that I just can't find it.

Sorry my bad I was a bit tired yesterday
I know exactly what your talking about but it may take some time to hit the search bar at the top and find the right thread

It may even be one of the stickies

No problem, brother. I've been having a heck of a time finding it. I know I saw it in a thread on here before, I was just hoping someone would be slightly more familiar with it. The search is on for me, hopefully I'll come across it or someone will be able to direct me to it. I've got some information on another board that may help me in concocting a formula, but nothing too direct just yet.

PCT Calculator | Post Cycle Therapy Calculator

This tool offers information remarkably close to what I am looking for. The problem is, that it restricts the information to injection patterns. I am not necessarily injecting every two days or three days, I have variations in the patterns. Would anyone happen to know the formula behind it?

I may be able to steal it from any backend javascript.
