There are a lot of ways to make up a good pct. A serm is always recommended to have on hand but you may not need to use it for hdrol but still a good idea to have one. A good pct could look like this.
Clomi , sustain alpha, toco-8, endo amp, HGHup.
I really like the trs from primordial performance for OTC pct. Also hghup has many great effects that would be of benefit in pct increase gh, androgen receptor density and some test boosting.
