You're asking a question that has been answered on this forum plenty of times. (And I'd be pleased to know what do you actually consider a safe cycle around here)
My suggestion would be to read the "Stickies" on these forums. The answer to your question is in them, plus much more. There is some really solid advise in the forums, that has been developed and posted to help educate New AAS users and Advanced AAS users. If you had read through all the stickies, you would not have asked that question. Make sure to read them ALL! Even (especially) the diet ones!
Sounds to me like you've been reading (maybe some inaccurate info, as 98mg/day is a lot, especially for a beginner), and researching. But do yourself a favour.... keep an open mind when researching. DO NOT just retain the information that supports what your planning to do. Because I have never read any info that would have supported, or suggested, a 19 yr old to run an oral only cycle.
I'm not hating on you or giving you a hard time. I wish I had the amount of natural test that you have at your age, without the introduction of AAS. I'm jealous of it lol! Damn you LOL!
But being here on this forum is the right thing for you! Ask lots of questions, and learn from the criticism that you're getting. And don't take them personally! Go research what some of these guys (/girls) are actually saying to you!
Make sure you read the stickies! It's for your own good! After your done reading them, Im sure you'll have more questions for the fine folks on the forum!
Cheers. And Good Luck!
