What people combine, and why
A stack is two or more peptides used together toward one goal. Most have picked up names that stuck. Here is what is in each one, what the parts do, and how much evidence there actually is for combining them, which is usually less than the pages selling them suggest.
Healing and repair
Injury, tendons, joints and gut lining.
Skin and appearance
Collagen, firmness, scars and how skin ages.
Muscle and body composition
Building lean tissue, losing fat, or both at once.
Weight and metabolism
Appetite, blood sugar and how much you burn.
Or start from the goal
If you know what you are trying to fix but not which peptides go with it, these guides cover every compound studied for it, not only the ones that come in a named stack.
A stack is a guess made for the average person.
You are not the average person, and the parts of this that are genuinely individual are readable. Upload data you already have and we score 39 peptides against your own variants, including the ones your results give you no reason to bother with.
