# Dihydroboldenone (DHB)

*Also known as: DHB, 1-Testosterone Cypionate*

1-testosterone (DHB); potent, non-aromatizing. Limited human PK data.

## Overview

Dihydroboldenone (DHB, 1-testosterone) is a DHT-derived analog of boldenone, used as an injectable anabolic despite a near-total absence of human pharmacokinetic data. As a 5-alpha-reduced compound it cannot further aromatize to estrogen, producing a dry, non-estrogenic anabolic profile distinct from its boldenone parent. The compound has an estimated roughly 216-hour half-life, modeled anecdotally rather than from controlled study, and complete bioavailability, supporting twice-weekly dosing of the cypionate ester form that is typically supplied. Effects include lean mass and strength gain without water retention, while known practical issues are injection-site pain and irritation given the compound physical properties, alongside the standard lipid and hematocrit monitoring needs of non-aromatizing androgens. Harm reduction centers on the understanding that the pharmacokinetic model is anecdotal and approximate and on rotating injection sites given the documented post-injection pain.
