I think you'll do fine stacking TB500 and BPC. I think those two would be good enough but the key is to run them at least 16 weeks. I know that's a long time but to be most effective that's what you have to do.
Make sure you check out the Deca from domestic supply. They also have excellent NPP as well. If you want to keep the site cycle shorter, you can always go with the NPP route.
I honestly haven't used KLOW yet but I've used several different healing peptides. I would say it's definitely worth a shot because it combines four different peptides all in one.
Amazing offer from Domestic Supply once again. Winstrol is a great option. You can load up and you can store it for many years as well. It'll still be good to use.
In terms of weight training, I would start lifting and stick to the compound lifts, things like squats and deadlifts for example, and flat bench. Those will really build your strength back.
Domestic supply always has great products at a great price, and Beligas is one of the top brands in the world. Make sure you take advantage of this amazing sale.
