Equipoise
Boldenone ester, injectable. Half-life 5.1 days.
Also called EQ, Boldenone undecylenate
Serum concentration from a single dose
single 100 mg dose over 3.7 weeks, vertical lines mark each half-life elapsed since the peak
What the numbers mean
The cited study puts the terminal half-life at 5.1 days, much shorter than the 14 days commonly repeated for boldenone undecylenate. The study figure is what the curve uses, so the plateau arrives in under four weeks rather than ten. Heavy ester weight leaves about 63% active boldenone.
The active fraction is the share of each milligram the model treats as reaching circulation as active compound. For an injectable that is ester weight: a milligram of enanthate is not a milligram of testosterone. For an oral it is bioavailability, the share that survives the gut and the liver, which is why some orals sit far below 100%. How the model works.
Where these numbers come from

Common questions about Equipoise
What is the half-life of Equipoise?
The model uses a terminal half-life of 5.1 days for Equipoise. For an injectable that figure is the rate the oil depot releases the compound rather than the rate the body clears it, which is why it runs longer than the half-life of the ester itself.
How long does Equipoise take to reach steady state?
Roughly 3.7 weeks, on a schedule that does not change. Steady state is conventionally taken as five half-lives, the point at which each dose is clearing about as fast as the next one arrives, and at a half-life of 5.1 days that puts Equipoise at 3.7 weeks of climbing before the curve flattens.
How long does Equipoise stay in your system?
About 4 weeks after the last dose for the serum level to fall to a few percent of where it was, on the same five-and-a-half half-life reasoning. That is the modelled blood level only. It is not a detection window: metabolites are found by testing long after the parent compound has gone, and this model says nothing about that.
