No need to worry about blood test's w/ those other products, PP products are all you'll need. I'm very impressed w/ their profesionalism and customer service.
I've read MULTIPLE posts about PP products and talked to several friends (w/ blood test's) who swear by Sustain. There are probably over 100 people on elite that have used and will continue to use these products. I have recovered fully when using Sustain and now Sustain Alpha in PCT. I haven't read anything positive (not to say their isn't) about AndroGenerator.
Another positive is PP always responds to pm's answering any questions I've had on their products, and very fast too.
**There are other products like unleashed and post cycle that can contribute to a goo PCT, but there is no need for AndroGenerator when you have PP.
