Single Vial PeptidesWhat is a peptide?
A peptide is a short chain of amino acids. Insulin is one. So is the ingredient in Ozempic. Here is the plain version, and what one research vial is.
The journal
A guide, grouped. Start with what the word peptide means, including collagen powder and a face cream, then what one research vial is. Tirz, reta, sema, and the other names people type. Not a lecture. Not a protocol.
Start here
What the word means, why a powder and a cream are different products, and what one research vial is.
Collagen powder and a face cream are not this vial
Most peptide pages online are about a scoop of collagen powder or a skin cream. This shop sells a dry research vial. Those are different products.
What scientists mean by peptide
The genome institute says a peptide is usually 2 to 50 amino acids linked by peptide bonds. MedlinePlus explains GLP-1, the hormone behind the Ozempic class. A research vial is not that medicine.
New here and just curious about one vial
A plain intro for someone who has only read about peptides and wants to know what one USA vial actually is.
What you are actually buying when you buy one vial
A single research vial is dry powder in a sealed bottle, at least 99% pure, fill within 10% of the label, shipped free from the USA.
What 99% pure and a 10% fill actually mean
Every Single Vial research vial is at least 99% pure, and the amount inside is within 10% of the label.
How to read a research-vial label
A research-vial label is a name, a milligram number, at least 99 percent purity, and a fill within 10 percent of that number.
Milligrams, milliliters, units, gauge, and length are five different numbers
A video can say 10, 31, or 6. Those can be a weight, a volume, a syringe mark, a needle thickness, or a needle length. Here is which number is which.
Units are a ruler, not a dose
On a U-100 syringe, 100 units is 1 mL and 10 units is 0.1 mL. The mark does not know the milligrams. Here is the harm-reduction math.
Why "0.1 mL" from a video is not a dose
A volume like 0.1 mL is not a dose unless you know the concentration. Here is the plain math, and who to ask if a doctor prescribed the medicine.
Ten units on a video is not your milligrams
Someone on a video says ten units, or twenty-five, or forty. That number is a mark on their syringe. It is not the milligram number on your vial.
Names on the shelf
One note for each name people type. The price is one vial. The biology is quoted from someone else.
What people mean by tirz, reta, and sema
Tirz, reta, and sema are the short names for tirzepatide, retatrutide, and semaglutide. Single vials of each, from a USA shop.
One vial of tirz, and what that word means
Tirz is tirzepatide. Here is the price of one single vial, from 5mg to 120mg, shipped free from the USA.
One vial of reta, before the brand exists
Reta is retatrutide. Single research vials, from 5mg at $35 up to 60mg at $200. Not FDA approved. Shipped free from the USA.
One vial of sema
Sema is semaglutide. One 5mg research vial is $35, shipped free from the USA. Not the Ozempic or Wegovy pen.
Retatrutide is still not approved
Retatrutide is Lilly's unapproved investigational drug, with a planned FDA filing in early 2027 and a narrow access program opened in August 2026.
BPC-157, one 5mg vial
BPC-157 is the peptide people just call BPC. One 5mg research vial is $35, or two for $60. Shipped free from the USA.
TB-500, one 5mg vial
TB-500 is a research fragment of thymosin beta-4. One 5mg vial is $35, two for $60, shipped free from the USA.
Wolverine is two peptides in one vial
Wolverine peptide is a nickname for BPC-157 plus TB-500 in one vial, not a molecule with its own paper.
Wolverine, GLOW, and KLOW are just blends in one vial
Wolverine is BPC-157 plus TB-500. GLOW adds GHK-Cu. KLOW adds KPV. CNN, Scientific American, Reuters, Fox, and Johns Hopkins are quoted on what people claim those names do.
GLOW and KLOW are blends
GLOW and KLOW are nicknames for blends in one vial, not single peptides. Papers here are about the parts.
GHK-Cu and KPV, one vial each
GHK-Cu is the copper peptide. One 50mg vial is $35. KPV is one 10mg vial for $40. USA shipping.
NAD, CJC, sermorelin, and tesa, in plain names
NAD+ vials, CJC-1295 no DAC with ipamorelin, sermorelin, and tesamorelin. Single-vial prices from a USA shop.
CJC-1295, no DAC, and ipamorelin
Papers and an FDA briefing on CJC-1295 with DAC, no DAC, and ipamorelin. This $40 vial is the no-DAC blend. Research only.
Sermorelin acetate in the record
Sermorelin acetate was Geref's ingredient. Those FDA applications are discontinued. This 5mg vial is not Geref.
Tesamorelin and Egrifta
Egrifta's label states its tesamorelin indication. A research vial on this shop is not that prescription product.
MOTS-c, in normal words
MOTS-c is a mitochondrial peptide studied in mice. It is not FDA-approved. Some clinics outside the US offer it. That is not a country approval, and it is not a dose from us.
Prices and the record
A pen, a compounded prescription, and a research vial. Prices and the public record. The Lilly injection-site note is about a prescribed pen only.
Brand, compound, and research are three prices
Zepbound, Mounjaro, Wegovy, and Ozempic prices next to compounded monthly prices and this shop's research-vial prices. Same names. Different products. The unit is written next to every dollar.
Two names, one chemical, and a pill collecting diagnoses
Mounjaro and Zepbound are both tirzepatide. The second name opens a second insurance door. Foundayo is approved for weight, and Lilly is studying it for a much longer list.
Compounded and research are different paperwork on a shared bulk market
Compounded GLP-1s and research vials are not the same product. Import records show the same foreign bulk ingredients filed under both descriptions, and the testing words used to separate them are often not a legal standard.
Compounded semaglutide and tirzepatide after the shortage
After the FDA ended the tirzepatide and semaglutide shortages, a 2025 secret-shopper study still found most clinics offering compounds.
Lilly's pen is the base. Salt is a different label.
Mounjaro lists tirzepatide, not a tirzepatide salt. The FDA says approved semaglutide is the base, and that sodium and acetate salts are different ingredients.
Who is selling compounded GLP-1s, and who actually got a letter
Four prescriptions a month is the pharmacy's count, not the patient's. Med spas and 503B facilities are not inside that line. FDA warning letters number about a hundred. The sellers number in the thousands.
The July 2026 peptide vote is not an FDA approval
MedPage and Pharmacy Times counted the July 2026 peptide votes. Both say a committee recommendation is not FDA approval.
Brenipatide is the list. Eloralintide is the E.
Lilly is studying two different unapproved drugs. Brenipatide is the long-acting GIP/GLP-1 on the alcohol, smoking, and mood list. Eloralintide is the amylin agonist. This shop sells neither.
Where a prescribed under-the-skin shot actually goes
For a prescribed medicine like Mounjaro, Lilly says stomach, thigh, or the back of the upper arm. Those are the fatty spots. The label is the instructions.
What other people wrote

What CNN, Fox, and the other outlets wrote
Quotes from CNN, Scientific American, The Guardian, NPR, Fox News, The Verge, Reuters, and Johns Hopkins on Wolverine, GLOW, KLOW, BPC-157, TB-500, and the other names in this shop.
Hollywood named a peptide. San Francisco started companies.
Hailey Bieber in The Hollywood Reporter, the California Peptide Club in Twin Peaks, and the San Francisco companies taking the meetings. The quotes are theirs. The vials here are research material.
What papers say about BPC-157
Quoted notes from a review, an FDA briefing, and the Federal Register on BPC-157, not a protocol.
What papers say about TB-500
Quoted notes from doping papers, an FDA briefing, and WADA on TB-500 and thymosin beta-4, not a protocol.
What papers say about GHK-Cu
What published papers say about GHK-Cu, the copper peptide. Quotes from Pickart and Maquart. Not a protocol.
What papers say about KPV
KPV is Lys-Pro-Val, the end of alpha-MSH, in the papers opened for this note. Not a protocol.
MOTS-c, in the words of the papers
Quotes from Lee 2015 and Reynolds 2021, both mouse experiments, and from FDA on MOTS-c. A 10mg research vial. Not a protocol.
What the record says about NAD+
What Cleveland Clinic says NAD+ is, and the two research-vial prices in this catalog. Quotes, not a protocol.
Sport
Gym talk, and what the anti-doping lists actually name.
Nobody has counted the bodybuilders
There is no census that 99 percent of bodybuilders use peptides. UCLA, Harvard, USADA, the WNBF, and NPC natural shows say what they actually checked.
Which peptides are banned where
The 2026 WADA list, the 2027 wording change, and the different clocks at the WNBF and NPC natural shows. Semaglutide and tirzepatide are monitored, not banned, by WADA.
Not a peptide note
Screening. It is not about a vial. It stays in the journal so it is not hidden.
Not enough evidence" is a shrug, not a clean bill of health
The USPSTF tells women to get screened for chlamydia and gonorrhea and tells men the evidence is insufficient. That is not the same as saying straight men are fine. Get tested anyway.
