1-Testosterone (Dihydroboldenone/DHB) is the 5α-reduced form of Boldenone, making it essentially the DHT version of Equipoise. This injectable compound provides high anabolic activity with low androgenic effects, similar to Primobolan but stronger, earning comparisons to ‘injectable Winstrol’ for its hardening effects.
DHB promotes quality lean muscle gains, increased vascularity, and significant strength improvements without water retention. Users often describe a recomposition effect with simultaneous muscle gain and fat loss, along with improved appetite and endurance similar to its parent compound Boldenone.
The compound is praised for providing Trenbolone-like results without the psychological side effects - users feel ‘clean’ on DHB with natural-feeling progression rather than the harsh intensity of stronger compounds. However, DHB has one major drawback: severe post-injection pain (PIP) that can cause flu-like symptoms, fever, and inflammation.
Many users experience painful welts, swelling, and systemic inflammatory responses that can make training difficult. The compound is often diluted with other oils or used at lower concentrations to manage the injection pain, but this remains the primary limiting factor for most users.
