List of Peptides and What They Do: Every Peptide Pepti Prescribes, in One Table
This page is the index for the rest of the library. Each row links the product page and the full reference page for that molecule, where the studies, FDA status and directions are set out in detail.
Treatments mentioned
Peptides are short chains of amino acids, and each one does a different job, so a list of peptides is really a list of very different molecules that happen to share a chemical shape. The ones Pepti prescribes fall into a handful of groups: GLP-1 medications such as semaglutide and tirzepatide, growth-hormone-axis peptides such as sermorelin and tesamorelin, repair peptides such as BPC-157 and TB-500, and smaller groups for skin, focus, sleep, intimacy, immune function and mitochondria. Several products sold alongside them, including NAD+, L-carnitine and B12, are not peptides at all. Every description below says what the molecule is and what research has looked at, not what it will do for any one person.

What makes something a peptide
A peptide is a short chain of amino acids joined by peptide bonds. Two amino acids make a dipeptide, three a tripeptide. GHK-Cu and KPV are tripeptides, ipamorelin is five amino acids, oxytocin nine, BPC-157 fifteen, sermorelin twenty-nine and semaglutide thirty-one. The boundary with proteins is a convention: the FDA's working definition treats a chain of 40 or fewer amino acids as a peptide and anything longer as a protein. Growth hormone, at 191 amino acids, is a protein.
The order of amino acids, the sequence, is what makes one peptide different from another. That is why the word "peptide" describes a shape, not a purpose. BPC-157 and semaglutide have no more in common pharmacologically than aspirin and insulin. The fuller explanation is in what are peptides.

GLP-1 medications
These are the most studied peptides in medicine, with large randomized trials for the use they are prescribed for. Both are once-weekly injections from dose-specific vials, and both exist as FDA-approved manufactured products; the compounded versions are not those products.
| Peptide | What it is | Reference | Price |
|---|---|---|---|
| Semaglutide | A 31-amino-acid analogue of GLP-1, the hormone the small intestine releases after a meal, modified to last about a week | What is semaglutide | From $99/mo |
| Tirzepatide | A 39-amino-acid peptide built on the GIP backbone and engineered to act at both the GIP and GLP-1 receptors | What is tirzepatide | From $159/mo |
The class as a whole is explained in what is a GLP-1, and the two are compared in semaglutide vs tirzepatide.

Growth hormone axis peptides
All of these act on the pituitary rather than replacing its output. Sermorelin, CJC-1295 and tesamorelin are versions of growth-hormone-releasing hormone (GHRH) and bind its receptor. Ipamorelin and hexarelin mimic ghrelin at a separate receptor. None of them is growth hormone, and Pepti does not prescribe growth hormone; see is HGH a peptide.
| Peptide | What it is | Reference | Price |
|---|---|---|---|
| Sermorelin | The first 29 amino acids of GHRH, the shortest fragment that keeps full activity | What is sermorelin | $229/mo |
| Tesamorelin | The full 44-amino-acid GHRH with a cap that slows its breakdown; the active ingredient of an FDA-approved product for one indication | What is tesamorelin | $249/mo |
| Ipamorelin | A five-amino-acid synthetic ghrelin mimetic, described in 1998 as the first selective growth hormone secretagogue | What is ipamorelin | $239/mo |

In the catalog, but not peptides
Several products are prescribed and injected the same way as peptides and sit in the same catalog, but they are not built from a chain of amino acids. Glutathione is the borderline case: it is technically a tripeptide, three amino acids, but it works as an antioxidant inside cells rather than as a signal.

|---|---|---|---|
| NAD+ Injection | A coenzyme every cell makes, used in energy metabolism; 1000 mg per 10 mL vial | What is NAD+ | $249/mo |
| NAD+ Injection (500 mg) | The same coenzyme at half the concentration, 500 mg per 10 mL vial | What is NAD+ 500 | $229/mo |
| Glutathione | A tripeptide of glutamate, cysteine and glycine, the main antioxidant inside cells | What is glutathione | $199/mo |

How every product on this list is supplied
The format is the same across the catalog. Each product is a multi-dose vial of sterile solution, shipped ready to use, so there is no powder to mix. Directions are printed on the vial in millilitres and in units on a U-100 insulin syringe, and each vial is sized to last about four weeks at those directions. Injectables ship with sterile syringes and alcohol prep pads, refrigerated with ice packs. Refills run every 28 days, one vial per fill. More is in how long does a peptide vial last and do peptides come pre-mixed.

What this list can and cannot tell you
A list is useful for orientation and not much else. The evidence behind each row ranges from large randomized trials (semaglutide, tirzepatide, and tesamorelin for its approved indication) to animal and cell work only (BPC-157, TB-500, KPV, MOTS-c and many others). The reference pages say which applies to each molecule, in those words. None of the compounded products is FDA approved, because compounded medications never are.
Choosing from a list is also the wrong way round. The useful question is what you are trying to change, and whether there is a peptide with evidence behind it for that. Your physician sets your directions after reviewing your intake, history and medications, and may suggest something different from what you came in asking about, or nothing at all.

Where to get a peptide prescribed
None of these can be bought legitimately without a prescription. Sites selling them "for research use only" are not accountable for identity, purity, sterility or concentration; see research peptides vs prescription peptides. The prescription route:
- Complete a free online intake covering your history, medications and what you want help with.
- A physician licensed in your state reviews it, usually within 24 hours.
- If it is appropriate, a PCAB-accredited, FDA-registered US 503A pharmacy compounds it to that prescription. Lot test results are published at /quality/lab-results.
- It ships refrigerated with your directions printed on the vial.
- Your physician stays reachable for questions and dose changes.

Common questions
List of Peptides and What They Do, answered.
By use, the main groups are GLP-1 medications, growth-hormone-axis peptides, repair peptides, and smaller groups for skin, focus, sleep, intimacy, immune function and mitochondria. Chemically they are all short amino-acid chains; the sequence is what makes each one different.
The most studied and most prescribed are semaglutide and tirzepatide, the GLP-1 medications. After those, BPC-157 is the peptide most searched for, although its evidence is animal and cell research.
The body's own peptides mostly act as signals. Insulin, GLP-1, oxytocin and growth-hormone-releasing hormone are all peptides. Medical peptides are synthetic copies or analogues of those signals, or of fragments of larger proteins, so each one acts on its own receptor or pathway.
Some peptide molecules exist as FDA-approved manufactured drugs, including semaglutide, tirzepatide, bremelanotide (the molecule in PT-141), tesamorelin and oxytocin. Compounded peptides, including every product on this page, are not FDA approved. See are peptides FDA approved.
No. NAD+ is a coenzyme made of two nucleotides, not amino acids. It is listed with peptides because it is prescribed and injected the same way. See is NAD a peptide.
Growth hormone is a 191-amino-acid protein, well past the usual 40-amino-acid boundary for a peptide. Pepti does not prescribe it. The growth-hormone-axis peptides on this list prompt the pituitary to release its own; see is HGH a peptide.
No. Collagen peptides in a supplement tub are hydrolyzed protein fragments taken as food. They are not signalling molecules and are unrelated to the prescription peptides on this list.
No. Anabolic steroids are small lipid molecules that act on the androgen receptor. No peptide on this list binds that receptor. See peptides vs TRT and steroids.
Some physicians prescribe more than one, and the blends on this list exist so one injection can replace several. Whether a combination suits you is set out by your physician after reviewing your intake. See can you take two peptides together.
Every product on this list is an injection. Most peptides are broken down in the gut if swallowed, which is why injection is the standard route. See can you take peptides without needles.
At Pepti, from $99 a month for semaglutide to $289 a month for the four-peptide blends, all-in, covering medication, physician review, refill management and shipping. See how much do peptides cost.
No. Bloodwork is not required for any Pepti treatment. If your physician wants labs for your care, they'll ask through your account. The free assessment goes to a physician licensed in your state. A consultation does not guarantee a prescription.
