Propionate guys updates?

With daily injections there are no peaks and troughs - well, there likely are but they are so small as to be imperceptible.

Not true, prop falls sharply at 24h (+/- 6h). For some people (eg. Vince Carter) this can be a dramatic noticeable fall in levels, within a day. With daily injections of prop, everyone experiences a dip before injection (look at the prop graph, superimposing several daily injections creates twice the levels at 12h post injection compared to 24h post injection)
 
I've been saying it that even with daily shots you have a peak, and then a trough. Stable is misunderstood as some sort of constant level and that's a mistake. Less variance in the peak and trough is as good as it can get.

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.
