[QUOTE="Cataceous, post: 162881, member: 38109"] In my opinion even weekly injections of undecanoate would give little variation in serum testosterone. Even with abrupt protocol changes, any yo-yoing is going to take place over weeks. Play around with this site to get a sense of what happens: [URL="https://steroidcalc.com/index.html"]SteroidGraph - Graph your cycle[/URL] A small complaint is that I think they use too fast of a rise time for testosterone undecaoate. The other esters result in fairly rapid elevation of serum testosterone, but I think undecanoate has a relatively longer rise compared to its effective half-life. As for the half-life, it's not applicable until after peak serum testosterone is attained. Then there's a gradual decline in levels, which is modeled reasonably well by saying that the rate of decline is proportional to the amount present. From basic calculus this results in an exponential decay, of which the half-life is a useful parameter—a constant time from [I]any[/I] starting point after which the hormone level drops to half that of the starting point.
