Automatic summary · not editorially reviewed

In this video description, the creator ranks semaglutide, tirzepatide, retatrutide, BPC-157, Epitalon, MOTS-c and NAD+ and calls exercise the only S-tier item. All claims are the creator's; the video and transcript were not reviewed. [1]

  1. The creator says semaglutide works for weight loss by activating GLP-1 receptors and making people less hungry, and warns of muscle loss without lifting weights and enough protein. [1]

  2. The creator reports 50% more blood vessel formation in injured legs with BPC-157, but states this was in rats, and says it has only been studied in 30 humans ever. [1]

  3. The creator says Epitalon and MOTS-c have only been shown to extend lifespan in flies, mice and rats, with no reliable human studies, and ranks exercise as the only S-tier item. [1]

Creator's weight-loss peptide tiers

The description says semaglutide (Ozempic) works for weight loss by activating GLP-1 receptors, making people less hungry. The creator warns of muscle loss without lifting weights and enough protein, and calls nausea and diarrhea quite common. The creator says lean people should not use it to get shredded, but calls it safe for overweight people when a doctor prescribes it, placing it in A tier in the right context. Tirzepatide activates two receptors, causes even less hunger and more weight loss, and is also A tier. Retatrutide activates three receptors and causes even more weight loss, but is not yet FDA approved, so the creator gives it B tier for now. [1]

BPC-157: rat vessels, few human studies

The description says BPC-157, called the wolverine peptide, claims to heal injuries. The creator reports 50% more blood vessel formation in injured legs, but states this was in rats. The creator also says it has only been studied in 30 humans ever. Anecdotes are described as strong, yet most injuries heal on their own, so it is hard to know whether BPC-157 is working. Until there is more science and quality control, the creator gives it a low C tier. [1]

Longevity peptides, NAD+ and exercise ranking

For anti-aging, the creator says Epitalon and MOTS-c have longevity mechanisms but have only been shown to extend lifespan in flies, mice and rats, with no reliable human studies and sketchy sourcing; both get F tier. NAD+ is called the most popular longevity peptide, but the creator notes it is actually a co-enzyme, not a peptide, and that the human science is weak; D tier. The last item is not technically a peptide either, but the creator puts it in S tier: exercise, said to make you look fitter and healthier, heal injuries and help you live longer. [1]

About this video

Creator description · original textText language: English

Peptides are everywhere, so let’s rank them. Only one is in S tier. Semaglutide, aka ozempic, works for weight loss by activating GLP-1 receptors, which makes you less hungry. But! You will lose muscle if you don’t lift weights and eat enough protein, and nausea and diarrhea are quite common. People who are already lean shouldn’t use it to get shredded in my opinion but It is safe for overweight people when prescribed by a doctor. In the right context: A tier. Tirzepitide. Same idea, except it activates 2 receptors, which makes you even less hungry and causes even more weight loss. A tier. Retatrutide activates 3 receptors which causes even more weight loss but it isn’t FDA approved yet so, B tier for now. BPC-157 (“the wolverine peptide”) claims to heal injuries. With BPC, there was 50% more blood vessel formation in legs with an injury, but… that was in rats. And it’s only been studied in … 30 humans. Ever. The anecdotes are strong, but most injuries heal on their own so it’s hard to know if it’s the BPC that’s working. Until we get more science and quality control, low C-tier. For anti-aging, Epitalon and MOTS-c have mechanisms for longevity but they’ve only actually been shown to extend lifespan in flies, mice and rats. No reliable human studies. And sourcing is sketchy. F tier. NAD+ is the most popular longevity “peptide”, but it’s not actually a peptide, it’s a co-enzyme. The human science is really weak anyway. D tier. The last one isn’t technically a peptide either, but it is in S tier. It makes you look fitter, healthier, it can heal injuries, and help you live longer... exercise.
