What is your rough budget if you dont mind me asking?
What are you looking to get out of your cycle? I mean do you want to bulk? Or lean bulk/recomp?
Im personally preparing for a H-drol cycle in the next few months, im planning from Now. Personally, if you dont have a SERM on hand, i would atleast make sure that you have a good AI on hand for your PCT, maybe you might want to go for a 6-bromo based PCT supplement as opposed to an AI like ATD...As well as a good Test booster...You may want to look into somethnig like Diesel Test Hardcore, maybe even get something for Cortisol control to add into your PCT 1week or 2 weeks after Your cycle finishes?
I dont want to get flamed here for not recommending a Serm, so please this is just my personal advice as the general consensus for H-drol is, it is quite mild in terms of suppression. Best thing you can do is, use the search function, and read through lots of H-drol users logs/reviews and see what They used for PCT, cycle length, and dosages they used. If you like, after you've done your share of reading more about H-drol, post up a PCT plan your thinking of, Im sure someone will be kind enough to tell you if it looks good or not.
All the best
