Check out needtobuildmuscle. They have really good supplements. I like their products. They're high quality and they really have a niche of servicing steroid users and bodybuilders.
The sweet spot for me with Masteron has always been 400-500 mg a week. I really like it. It's a great hardening option, but you need to be at low body fat first.
When it comes to these healing peptides, consistency is key. I have found that if you take them on a daily basis or at least every other day, you'll have the best results.
Dbol is one of those oral steroids that really kicks in fast. It's got a super short half-life, so if you use it, you only have to run it three or four weeks.
