What the numbers mean

No pharmacokinetic study of its own exists, so the model borrows the peak and 6.9 day half-life of testosterone cypionate and rescales the level to sit with the rest of the boldenone family. Read the shape as cypionate, not as measured 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

No published reference is recorded for Boldenone Cypionate. Its figures are carried over from the compound database this plotter was built against, and should be treated as the weakest in the set.

Common questions about Boldenone Cypionate

What is the half-life of Boldenone Cypionate?

The model uses a terminal half-life of 6.9 days for Boldenone Cypionate. 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 Boldenone Cypionate take to reach steady state?

Roughly 4.9 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 6.9 days that puts Boldenone Cypionate at 4.9 weeks of climbing before the curve flattens.

How long does Boldenone Cypionate stay in your system?

About 5.4 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.
