Average Injection Beginner TRT Dose

[Deleted member 16042]

I just did that and see that you did use the same numbers there and I missed the error at that time. Fortunately it doesn't matter—you're creating the blend as intended and the only other variable is the dose size; your first paragraph above correctly conveys the important information:

4:3 blend, 4 parts cyp to 3 parts prop (7 parts) by weight in mg​

(When mixing, by volume it's 2:3 because cyp is 200mg/ml and prop is 100mg/ml.)​

4:3 gives total of 7 parts for proportioning​

The main thing is that the 4:3 ratio is by ester weights, mg TC versus mg TP. The different ester concentrations lead to the different ratio by volume, 2:3.

Got it, thanks

Got it, thanks

This may not clarify things, but for reference, here are the equations when the goal is to take a desired dose of testosterone and calculate the ester amounts with a 4:3 blend.

TT = dose of testosterone
TC = weight of TC in dose
TP = weight of TP in dose

TT = TC * 70% + TP * 83.7%
TC / TP = 4 / 3

Solving these equations for TC and TP:

TC = TT / (70% + 3 / 4 * 83.7%) = 0.753 * TT
TP = TT / (4 / 3 * 70% + 83.7%) = 0.565 * TT

In the example with TT = 5.6 mg you have TC = 4.22 mg and TP = 3.16 mg. The TC volume is 0.0211 mL, the TP volume is 0.0316 mL and the total dose volume is 0.0527 mL.
