Start with a goal
What are you actually trying to fix?
Most people arrive here with a problem, not a product name. Pick the one that sounds like you and you get every compound that has been studied for it, sorted by how much of that research was run in people rather than in mice.
Fat loss and metabolism
78What actually works for fat loss?
The most heavily trialled area on this site by a wide margin, and the one where the gap between marketing and measurement is small...
78 compoundsAgeing and longevity
45Does anything actually slow ageing?
The hardest question on the site to answer honestly, because a real longevity trial in humans would take decades and nobody has ru...
45 compoundsBrain, memory and mood
30Is there anything real for memory and focus?
The category with the widest gap between what is claimed and what has been measured in people. Several compounds here have genuine...
30 compoundsHormones and growth hormone
28What do the growth hormone compounds really do?
Growth hormone secretagogues, testosterone support and fertility. An area where the marketing leans on a real hormonal effect and...
28 compoundsMuscle and strength
27How do I build muscle, and how do I keep it?
Muscle is the tissue most tightly linked to how the second half of life goes. This covers building it, keeping it through weight l...
27 compoundsInjury, healing and recovery
25Will this help me heal faster?
Where the peptide world is loudest and the human evidence is thinnest. The gap between the two is the reason this section exists,...
25 compoundsImmune system and inflammation
20Can I do anything about chronic inflammation?
Inflammation is measurable, and that is both the strength and the trap of this category. A compound can lower a marker without cha...
20 compoundsSkin, hair and appearance
19Does anything work for skin and hair?
Cosmetic compounds, collagen, pigmentation and hair. Topical and injectable evidence differ enormously here and the pages keep the...
19 compoundsHeart and circulation
10What has been shown to lower cardiovascular risk?
The area with the hardest endpoints on the whole site. Cardiovascular trials count events, not markers, which makes the evidence h...
10 compoundsGut health
8What has been measured for gut health?
Gut barrier function, intestinal growth and the compounds used in short bowel syndrome. A small area with a couple of genuinely ap...
8 compoundsBone and joints
6What is real for bone density and joints?
Osteoporosis has genuine approved drugs with fracture endpoints. The joint and cartilage claims mostly do not have the same backin...
6 compoundsSleep
5Is there anything measured for sleep?
A short section, honestly. Sleep is heavily supplemented and lightly trialled, and this page shows exactly how little of the noise...
5 compoundsWhy these are not rankings
A goal page lists everything studied for that goal, including the things that were studied and did not work. The order is by how much human evidence exists, not by how promising something looks, and a compound sitting at the top of a list is not a recommendation. It is the one somebody actually ran a trial on.
Some of these sections are thin, and they say so. Sleep in particular is heavily supplemented and lightly trialled, and pretending otherwise would defeat the point of the whole site.
