HGH is definitely the GOAT. It's one of my favorite peptides and it definitely works well. You can always stack it with some of the healing peptides as well.
Tren is the absolute goat but has to be respected. Make sure you're using support supplements with it. Make sure you don't exceed 400mg a week unless you don't mind side effects.
Dbol is the GOAT but using it with deca and testosterone is way too much water retention. Make sure you have an AI with it. Aromasin or arimidex are the way to go and use n2guard as well.
