Jason,
LGD-4033 for 8 weeks is going to create suppression equivalent to running Test E (300--500) for 8 weeks...
--- Therefore, your PCT is inappropriate (i.e. isn't strong enough).
Do yourself a favor,
--- understand LGD-4033 is a powerful drug.
Until you gain more experience with these two SARMS,
--- I would strongly recommend curtailing LGD-4033 to no more than 4 weeks at a time.
And, as always, use the 1 to 1 ratio of cycle on; PCT off.
Good luck
