Always use the highest dose first! Your body take 2-3 months to recover 100% from a cycle. So no, you wont beable to recover in 4 weeks while on anavar and primo.
You always need clomid, and tapering does not work in bring back your hpta. If there is an androgen present, your hpta will still be suppressed. I highly recomend clomid 3 weeks after your last shot of sus. Use the anavar and primo to solidify your gains.
