I personally would step the test up as the cycle goes on if looking to use around 500mg, like so:
Month 1: 400mg
Month 2: 500mg
Month 3: 600mg
Then just add a DHT derivative the last 4-6 weeks, ideally the injectable Epistane but Winstrol is a fine option if you don’t want more pinning.
I would NOT use Yk11 along with either Epistane or Win in the same cycle, as all of these compounds are known to push your tendons to their limit. And on that note, if you plan to be training truly hard and heavy near the end, then all 3 might actually be poor choices & you may be better suited to just using the 2 bottles of TLB150 on the back end.
Understand this: as soon as you start taking any of the extra goodies you have, the SARMs and methyls, your lipids are going to get nasty and stay nasty for the rest of the blast. So don’t run them sooner than you can accept that. You could run 12 weeks of orals for maximum changes acutely, but it’s not a good longterm plan at all.
