I'll first give an opinion to everyone, and then an opinion to you John based on what I know about you.
Opinion to most recreational users(some of these doses are for ADVANCED people):
1) 300,450,600,or 750 test(depending on how advanced you are)
2) 600-750ish EQ with low trt test (depending on how advanced you are)
3) 600ish EQ with 300 test (if advanced enough)
I would absolutely not touch dbol/oxan/any orals whatsoever while bridging; unnecessary stress on your arteries and liver, especially during a "bridge".
In terms of GH, I wouldn't go over 2iu GH as a guy if you're a recreational user IMO. Would be nice to just stay off of it completely ...
:/
Obviously we're not talking about pro bodybuilder bridging here lol.
John, from what I know about you... I would just use 600EQ+1 pharm test AMP(250mg)/week for your bridges, and just keep donating blood and watching your HCT. If you're an avid GH user, I can't stop you(not sure if you are). If you are one, I would try to stay with 2iu 6days per week *PHARM GRADE*....but obviously you know your own goals and what you want :/
