Ok I am doing this partly out of memory and partly out of reading old posts. Drb was adamant to find the leading cause of pip. He brewed excellent gear that never piped, but would run across friends who were hurting badly.He would shoot it and get pip. Since he was a good brewer, he took all of the components that make up gear except for the hormone itself. Starting with just oil. Big pharm mostly used seasame, cottonseed or safflower oil. Today along came grapeseed oil and coconut mct oil. Drb took the 5 oils and injected a 10ml blend of them into his quad. Then injected another 10ml right into the same exact spot. Next day..no pip. Now on to the solvents that keep the gear dissolved.It is usually used at 10-20%. So he put 70% in oil and shot 5ml. Next day no pip. Then there is a sterilant in gear to keep it protected and it is usually present at 1%. DrB made a 10% solution in oil and shot 5mls. No pip. So where was pip coming from. Then he realized...all the gear that he ever got pip from was over 300mg/ml. He always made 200mg and sometime 250mg. Now he only did this experiment with deca,cyp,E and sus. He made 450mg/ml of each and diluted to 200. He shot all at 200, then all at 250 then all at 300 then all at 350 then all at 450. The 450 had him crippled. The 300 hurt. The 200-250 NOTHING. He then tells me..that is why big pharm makes it at 200!!
So his advice...never shoot anything over 300 if you are pip prone. So lets say you are doing a cycle of 1ml 450 testcyp, 1ml 200 deca, 1ml 200sus.You add the total mgs and divide by the total mls. So 450+200+200 divided by 1+1+1. So 850 divided by 3 =283mgs/ml that you are injecting.You are good to go. That is how we grew up loading syringes...being sure to not go over 300. We made blends right in the syringe and never exceeded 300mg.
So his theory is that too many mgs in too little oil cause the gear to crash in the injection site. As soon as it hits your watery somewhat salty tissue the gear falls out and forms crystals that keep re-crystalizing on top of crystals, causing large crystal formations.. leading to muscle splits,tears, and imflamation. Whether his theory is right or wrong does not matter, but if you follow his rule of injecting you will never get pip again. Now this is assuming you are seasoned users not virgin muscle.
I got kicked off line so this may or may not work.The site keeps logging me out.
