Brewing my own BAC water?

Stopped TRT in 2021 after 3 weeks IM—soreness and needle anxiety got to me. Been doing subQ since January. 8-week labs looked great except DHT was low, so bumped from 120 to 180 per week. Main SQ limit is injection volume. I do 3x a week splits and it works fine.

just grabbed some of this stuff and worried about injection sting. thinking about diluting more to dial it down — does anyone know if that actually helps? and where can i find sterile vials in the us?

Sourcing your own BAC water removes the supply chain variable. If something goes wrong, the cause is traceable.

DIY BAC is doable but the contamination risk isn't trivial - commercial BAC removes that variable at small cost.

the 'at least it is a variable you can control' framing is the honest version of the DIY argument - the sterility outcome of home brewing is genuinely uncertain and the certainty of the pharmaceutical version is the thing you are paying for, which at the cost of BAC water is not a meaningful expense. using something you know meets sterility standards for the carrier fluid is the lowest-effort risk reduction available in the whole protocol

The distilled water from a retail source has a different quality assurance profile than pharmaceutical-grade water for injection - retail distilled water is produced for appliances and humidifiers, not for injection, and the absence of pyrogen testing and USP sterility standards is the practical gap. for the carrier fluid in a compound that goes directly into subcutaneous tissue, the pharmaceutical water eliminates a sterility variable that retail distilled water does not
