Pro-hormones vs. natural testosterone boosters
I'm planning to start a bulking cycle next month and I was hoping to get some info/opinions on the pros and cons of pro-hormones and natural test boosters. I've used USP Labs Asteroid Stack (Anabolic Pump, Prime, Powerfull) in the past and had pretty decent size and strength gains. I was just going to do this stack again, but I decided to see what else is out there.
I've never used pro-hormones before so I'm not sure what to expect. I know they're supposed to give you crazy gains, but I've also heard of negative side effects like acne, mood swings, etc. Also, does it cause extra strain on your liver like steroids do? Are there any negative side effects after you're done with the cycle? Does it cause your natural test production to decline?
I was looking at the LG Sciences Trifecta Stack. Has anybody used this? Are there other stacks you would recommend if I decided to go the pro-hormone route? What about doing a combination of pro-hormones and natural test boosters?
I've also looked at some of the websites for the "gray market" anabolics (Cibex-o Labs, Pharma Pro, etc.) and I'm kinda hesitant to try any of those cause it seems like they're basically steroids, not to mention that they're expensive. Has anyone tried these?
I'm 5'8" and a lean 160 right now. I'm looking to get up to 170 in a span of 3 months, just to give you an idea of my goals. Any advice I can get is appreciated.
