Really…week five out of eight and just now you are concerned with PCT?
I have to say this, you should have had all this lined out BEFORE you started. You should have had all the things you needed before you ever pinned.
Typically PCT is Nolvadex at 40 mgs a day for two weeks then 20 mgs a day for two weeks.
A clomid only PCT is 100 mgs a day for two weeks then 50 mgs a day for two weeks. Just so you know some guys react to clomid and act like pregnant women on it. You won’t know until you use it. Mgs for mgs Nolvadex is a stronger binder which most guys like and tend to gravitate towards it. Some guys like to use both Nolvadex and clomid but this is being done less and less. If you do use both then cut the dosage strength in half.
I hope you have time to get your compounds for PCT.
As far as timing to start if you are using all short estered hormones like acetate, propionate and phenylpropionate then just wait 3-4 days after last injection and then start PCT. If you are using any long esters like enanthate or cypionate then wait at least two weeks after last injection.
