SteroidPlotter and mg/day

Recently discovered SteroidPlotter (SteroidPlotter - Graph your cycle) and thought wow that's so cool. I'm on trt and really keen on getting my dose correctly set. However, I have a quick question, does anyone know if the mg/day plots are mg of the ester or mg of testosterone, from my understanding 1mg enanthate is not 1mg of testosterone as only 75% of the ester is actually test?

I'm trying to understand whether my current protocol of 35mg every other day (IM) is theoretically super-physiological. I know from blood tests I respond extremely well to exogenous testosterone. I've attached a plot of my protocol against what I believe a normal healthy guy would be.

My goals in priority order are:-
  • healthy, happy and have optimised hormones for sex
  • muscle size and gym performance
I'm a 51yr old type 1 diabetic, been lifting for decades and 15st 2 and carry quite a bit of muscle.

That site is computing testosterone release, and does not include the ester weights. The fractions they use are reasonably close, but if you want better numbers then check out this post.
For example, T enanthate is 72.0% testosterone.

As for 35 mg TE EOD: It is 12.6 mg testosterone per day, which is roughly double what the average healthy young man produces naturally. With this protocol you are putting your second set of goals somewhat ahead of the first set. The first set of goals could probably be met with about half the testosterone, but a compromise might put you at 80-100 mg TE/week, as long as you don't have side effects and blood work is ok.

Thank you, I had a feeling I was on too much. I want to be high end for sure but not above high normal.
 
Steroidplotter has been renewed, big time, the old version can still be found, but many things seem to be off with the new one, they say they have really been digging into studies but for example i made a graph on daily propionate and there was hardly ANY variability in the levels. What do you guys think?

I saw this as well. I appreciate them trying to update the site, but there was really nothing wrong with it before as long as you knew it's use and limitations. The new version seems to raise more questions than answers. Sometimes simpler is better.
 
Usually, they reference the actual testosterone content, not just the ester. So for enanthate, you're right that it’s around 75% test, meaning 1mg of enanthate isn’t a full mg of testosterone.With your current protocol of 35mg every other day, you might be sitting at a higher physiological level, especially if you respond well to it. I’ve been on a similar journey, and I’ve found that tracking my doses really helped optimize my gains. When I was adjusting my protocol, I picked up some supplies from [edited by moderator], and they had some good options for what I needed.

Understanding Your Hormones

Estradiol (E2)

A form of estrogen produced from testosterone. Important for bone health, mood, and libido. Too high can cause side effects; too low can affect well-being.

DHT

Dihydrotestosterone is a potent androgen derived from testosterone. Affects hair growth, prostate health, and masculinization effects.

Free Testosterone

The biologically active form of testosterone not bound to proteins. Directly available for cellular uptake and biological effects.
