I just don't know, sir. I can speculate. Imo, most likely the raws. I feel like an ass saying that. Like any source is gonna pass the buck. What's in my mind is I've been doing this almost 20 years. I know how to synthesize product. All my other product is pip free and the recipes for most everything is the same. I haven't done anything different. I've heard it isn't just my test e. That there are other sources having this issue. These are all reasons i believe it's the raws. There's a process, which i don't claim to know what all goes in to the making of these compounds, but there's supposed to be a process at the end of making the test e raws where they rinse the chemicals out. I've heard From time to time the manufacturers rush the process and this can cause pip. This is my opinion based on what i see. Not sure how i could have made test e with pip doing exactly what i do every time using 1% ba and 15% bb. Seems to be probably about 10 to 15 percent of people complaining of pip. For test e that is way too much. Should be oloser to 1 percent. You'll never see a instance where 100 percent of the people have no reaction to a particular carrier. Anyways, that's the best answer i can give you. To be honest, there's no reason for me to not be honest about this. Wether it's my fault or not i guarantee my products and services so anyone that has contacted me has been taken care of. Bottom line, though is i have to find a solution. Cant throw away the test e raws and can't have that many people not happy and can't afford to keep replacing. I mean if all else fails first thing would be take test e off the list. You guys are more important than what the test e cost. I want to try and make a blend of maybe a third test e and 2 thirds test c. Or the same with sust or something. Maybe a blend with all 3 and see if that doesn't fix the pip issue. I don't know. Gotta figure something out.
