What the numbers mean

The same stanozolol base at 3.4 days instead of 9 hours, roughly nine times the duration for an identical compound. Note that the published time to peak of 7 days is longer than a 3.4 day half-life can support, so the figures behind this curve are internally inconsistent and its shape is unreliable.

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

The half-life and the peak concentration are both read from a published reference. Read it on PubMed.

Common questions about Winstrol Injectable

What is the half-life of Winstrol Injectable?

The model uses a terminal half-life of 3.4 days for Winstrol Injectable. 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 Winstrol Injectable take to reach steady state?

Roughly 17.1 days, 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 3.4 days that puts Winstrol Injectable at 17.1 days of climbing before the curve flattens.

How long does Winstrol Injectable stay in your system?

About 18.8 days 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.
