I am going to lay this out for you to think about it. To be honest, what you are planning or thinking does not make any sense to me..
If we are considering a cycle of osta or what ever drug that is not a supplement... first we have to know what is the goal. Probably it is gaining muscle, recompping, losing fat or a combination of those. Once we know the goal, we have to have a plan, so we can reach the goals. Same thing applies in many areas in our lives. At the moment, you do not have a plan, or your plan is half-assed plan. If we think about using steroids / drugs / hormones or what ever, you cannot / should not even consider a half-assed plan because it is a waste of time, it is bad for your health and you will not succeed.
So taking all these facts in consideration, you have to have a successful plan for a successful cycle. And following issues has to dealt with if you want to succeed:
- Time -> If you really want to get results, you need time. 4 weeks, is a REALLY short time to get successful results, what ever your goal is. So forget your 4-week or what ever plans, it is waste of your time to even think about it. To be honest, I would say 8 weeks is a total minimum and tbh I would have enough of the desired product on hand to even continue from there. What if the cycle really treats you well and you are not getting any sides, why would you quit on the exact 8 week mark, if you could do 10? Once you are under a drug that is affecting your body also IN a NEGATIVE way, I would at least personally take all the positive effects I can out from it. So again I am saying, forget those 4 week plans....
- You need a proper test base -> If you want to have a successful cycle, I really recommend you to have a proper test base. If you cannot use something like Trest (which I am not definitely recommending to you since you lack the knowledge) I would at least have some andro products stacked with the osta. It will help you to battle the possible lethargy. OF COURSE you can do a cycle without a test base, but there is always a possibility to get really bad lethargy sides, which you may not be able to handle. This is your first SARM cycle (I assume) so, you do not know how the Osta will affect you.. You cannot ask people from here (how it affected your testosterone).. you are a individual...
- You need a proper cycle support -> This is not a must, but this is suggested to have. And no I am not talking about liver support since I guess that is not needed... I am talking more or less about your lipid support / blood pressure support. I would at least grab couple bottles of some hawthorne berry extract for the bloodpressure support.
- You need a PCT (SERM) -> Yes, you need a PCT. You are playing around with your hormones here... do you want to be impotent or feel like **** all the time after your cycle? Do you want to keep any of those gains you just made in the past weeks/months? I thought so.... SO you need a real PCT and commonly they are either Nolvadex or Clomid or both combined and those are again.. DRUGS. Supplement companies are selling products with the word PCT in them, but they are not a proper PCT products. These kind of products definitely can be added to your PCT stack, but as a standalone, they will not properly bounce you back. (Search youtube -> PCT Explained).
And of course you need to train hard and eat correctly. There is no reason to do a cycle without doing it properly and following proper guidelines... it is a waste of time and can be really harmful for you if you do not do it properly.
I do not want to be an ass here... but there are so many young guns who buy these products with zero knowledge and think they can use it 4 weeks like they would use D-aspartic acid and get free massive gains and keep them all without proper guide lines..
Open your google, open your youtube and do yourself a favor and learn...
