The short answer
What is the difference between CJC-1295 and IGF-1 LR3?
CJC-1295 is a synthetic peptide built as an analog of growth hormone releasing hormone. IGF-1 LR3 is a longer molecule: a modified form of insulin-like growth factor 1, extended at one end and changed at position 3.
They are not two versions of the same thing. They sit in the same product family on our site, but each is its own compound with its own record, its own label and its own vial size.
We carry CJC-1295 in 10mg vials and IGF-1 LR3 in 1mg vials. Both come as freeze-dried powder, and both can be bought as a single vial or a kit.
If you are unsure which one your work calls for, start with the name on your method sheet. Match it to the full product name on the page, then check the size.

Make-up
How are the two molecules built?
CJC-1295 is made by chemical synthesis, one amino acid at a time. The name Mod GRF 1-29 points to its parent: the first 29 amino acids of the releasing hormone, with changes at several places.
IGF-1 LR3 is a recombinant protein. That means it is made in a living host and then purified, not built chain by chain. It has 83 amino acids, so it is a much larger molecule than CJC-1295.
Because they are different kinds of molecule, read each certificate for the compound you are ordering. Check that the report names that compound.
Names
Why do people search for the two together?
The two names are close in length and both start with a short code, so it is easy to mix them up.
Read the full name and the size on the label before you add anything to a cart.
A quick rule: if the vial says 10mg and the product is CJC-1295, it matches our record. If the vial says 1mg, you are looking at IGF-1 LR3.

Check first
What should you check on a certificate?
Ask for the lab report. Look for the lab name, the test date, the purity number and the measured mass. A report with none of those tells you little.
For either compound, the report should name the compound it covers. Not every compound we sell has a posted report yet, so check the certificate page for the one you want.
For the full list of checks, see our certificate page and our supplier checklist.
If the report you need is not posted, contact us through the site before you order and we will tell you what is on file.
- 01
Name
The report names the same compound as the vial.
- 02
Purity
A purity number from the lab, with the test date.
- 03
Mass
A measured mass that fits the compound.
Single or kit
Should you get one vial or a kit?
A single vial suits a first test or a method check. A kit holds several vials of the same size, for a longer series of work where every run should start from the same material.
If you plan to run both compounds in one project, you can add one vial of each to the same cart. They stay as separate vials with separate labels, so nothing is mixed in the box.
The two compounds come in different sizes, so a kit of one is not the same weight as a kit of the other. Check the size on each product page.
See the CJC-1295 page and the IGF-1 LR3 page for the current sizes and specs.

Questions
Common questions
Is CJC-1295 the same as IGF-1 LR3?
No. They are two different compounds. CJC-1295 is a synthetic analog of a releasing hormone, and IGF-1 LR3 is a modified recombinant form of insulin-like growth factor 1.
What size vials do you carry?
CJC-1295 comes in 10mg vials and IGF-1 LR3 in 1mg vials. Each is sold as a single vial or a kit.
Are the two sold as a blend?
No. Each is its own vial with its own label.
Where can I see a certificate?
Our certificate page lists the reports we have posted. Not every compound has one yet, so check the one you want.
Are these for human use?
No. Both are sold for laboratory research only. Not for human or veterinary use.
