It just works. A bombs and Fina were the best ever tried. People make fun of "Bro Science" today, but that was all we had, and most did not even have that. They just did what other uninformed people did.
I bought the redi-jects because I knew they were harder to fake and less worth faking Same deal at that time with the amps versus 10ml bottles.
Remember the first run of "Bladders". And the UK friend with the paper soaked orals like blotter acid? Good Times. Good Times. LOL
People are so worried today. There is a thread on how to manage a week on a cruise ship. It matters so little. People are trying to measure things with the decay of Cesium oscillations when a sundial would do.
Test, DBol, Abombs, and Tren have built more muscle than all the esoteric stuff combined. It is like building a car for speed and worrying about a better air filter than just putting a Supercharger on the engine. Do the easy stuff first. You can get 95% of stuff easy, but people waste most of their time and money on the last 5%. If you look at engineering history, look at athletic history, that last 5% can cost more in money, time, effort, worry, than the first 95%. It only matters for the elite.
