Testosterone and Winstrol are definitely the GOAT. I also like TBol a lot. You can really mix and match them. You can do TBol the first 4 weeks and Winstrol last 4 weeks.
You are a lucky guy for sure. This is a great touchdown. Very impressive. And don't worry about the expiration dates; they'll be good for years to come even past expiration.
You're not going to go wrong going with the sources that the vets and the moderators on here recommend. Those are the best sources and they are tried and true.
In terms of what you can take, you can take something like HCGenerate. It's a natural testosterone booster; it'll make you stronger, and it's not going to ruin your hormones.
