After the first shorty, recovery or feeling "normal was fast, maybe 4-5 days with clomid therapy. However, if you continue with 2 on, 2 off, that timeframe lengthens. Something like 2 on 2 off, 2 on 2 off, 2 on 4-6 off would likely work okay in terms of being aggressive yet giving enough time to recover.
Is it a viable option? Absolutely. The thing I keep pounding though is that your expectations must be in the right place in order to be happy with the results. It's a decent option....think of how many people used the original MAG-10, or 4-AD-EC, or M1T, etc and got results they were pleased with.....how on earth could using real AAS at more solid doses and in stacks, with ancillary use and SERM therapy NOT be more effective over a similar timeframe?! Simple logic.
A fragile HPTA is going to be affected either way i would think. Shorties would help minimize that, but there are compounds and ancillaries that you could use in 8 weekers and probably recover from too.
