Nah man, many of us have leaped before looking. It was a learning experience for me and it taught me to definitely do my research prior. I have since done a couple other PH cycles with good results and am currently in my 1st injectable AAS cycle. This'll be my 6th week in. Talk about research; there's a lot that goes into injecting AAS lol. Great results thus far though!
You need to be concerned about keeping your gains. You're going to shred up, gain some lean muscle and strength, and then 3 weeks into your "PCT," everything will start dropping. You're all proud of yourself and excited, then boom, in a matter of weeks you lose most if not all and you're right back where you started. Hdrol is a fairly light compound in regards to PH's, but you'll still have good gains from it if you run it right. Side effects, I never experienced any, but I've been lucky in that respect as I haven't experienced many sides with anything. I did start to get some gyno and acne while on my current cycle, but I have the proper support supps to combat the gyno and started using an acne wash for my skin along with a lufa. I scrub the skin right off my body, so needless to say, my acne has also deceased lol. After cycle sides, I pretty much already stated them; lost a lot of my strength, tone, and some of my libido. It wasn't fun. Could have been a lot worse had I not had an OTC PCT, but I still wouldn't ever choose that over an actual SERM.
If you're going to go OCT for your PCT, I would stack a couple different compounds together to give your body as much help and recovery as possible. Stack with a cheap DAA and maybe some tribulus along with something I mentioned in a previous choice, or something else along those lines of your choosing. The cycle isn't worth your time if you're going to lose everything in the end. All it does is kill your determination and then you get on a more powerful PH wayyy too soon to make up for it. It's a sinking ship, man.
If you're making the decision and taking the step to start a cycle, do it right, or don't waste your time and just continue to use creatine. Your goal should be to continue to make gains while staying healthy.
And Erase is a good, cheap, effective Estrogen blocker. You don't want to over suppress your estrogen, but you don't want it to rebound during your PCT either. Erase keeps your estrogen from rebounding and bloating you up. It's a solid product, IMO.
