Bridging basically looks like this:
1. Run your cycle.
2. After your cycle run a good pct protocol such as the perfect PCT:

3. After the PCT protocol, run a SARMS bridge - such as the SARMS triple stack:
http://www.evolutionary.org/the-SARMS-triple-stack-protocol
4. After the triple stack, run a mini PCT. 4 weeks of the following:
clomid at 25mg/day
nolvadex at 20mg/day
HCGenerate ES at 5 capsules/day
n2guard at 3 capsules/day
5. Then wait 3-4 weeks, ideally get blood work done to make sure everything is in the normal range and start your next cycle.
With doing 1-5 you will continue growing off cycle and your natural testosterone production won't be suppressed. It is a healthier route all around.
