Turnibol is suppressive so you will need to PCT after. . Keep in mind PCT is only to give you a soft landing after a cycle. You would bounce back on your own in most cases on a short, low dose cycle like this.
50-80 mg/day is fine for turnibol. You could even go higher if you wanted to 100mg/day. I would keep this under 6 weeks. You will also want to use an organ protection product on any steroid cycle. N2Guard 7 caps/day.
For PCT i would wait 5-7 days until the tbol clears and then you would do Clomid 50mg/day and Nolva 40mg/day for 3-5 weeks. After that wait 3-4 weeks and get bloods. Others may chime in on this as it's a very short cycle so you may be able to get away with less. I don't know a ton about PCT as I am on TRT.
Order Geneza pharma from napsgear. My freinds and i have been using their products for years with 0 issues. They are prob the best lab out there.
Same with Ultima from Domestic supply.
The only way to know is to get baseline numbers and then introduce products one at a time to see how you and your bloods react and to have the products on hand to counteract any issues that come up.
Have you considered using SARMS instead?
@dylangemelli can give you a great layout to reach your goals and the PCT to go along with it.
It would be a good intro into PEDs.
