GH-axis secretagogues research peptides
GHRH analogues and ghrelin-receptor secretagogues, singly and as blends. The category where vial masses are smallest and per-milligram prices are therefore highest.
5 compounds, 5 vial sizes, from $5.00/mg to $8.00/mg. The cheapest per milligram here is Ipamorelin.

The 1-29 fragment of growth-hormone-releasing hormone.
A stabilised GHRH(1-44) analogue bearing an N-terminal trans-3-hexenoyl group.
A 28-amino-acid N-terminally acetylated peptide originally isolated from thymic tissue.

What is in this category
Two related groups. GHRH-family peptides - sermorelin, which is the 1-29 fragment of growth-hormone-releasing hormone, tesamorelin, a stabilised GHRH(1-44) analogue, and CJC-1295 without DAC, which is cataloged equally often as Mod GRF (1-29). And ghrelin-receptor secretagogues, principally ipamorelin. The CJC-1295 and ipamorelin blend exists because those two are commonly ordered together.
Why these look expensive per milligram
Small vials can look expensive beside a 100mg copper-peptide vial, but those figures are not comparable. Filling, capping, labeling and shipping costs do not shrink in proportion to vial mass, so fixed costs matter more at small masses.
Compare within the category and check the mass on each current listing. We publish a size only when a matching current supply testing record exists.
Naming, which is unusually messy here
CJC-1295 with DAC and CJC-1295 without DAC are different molecules with different masses, and vendors are not always careful about which they list. Everything in this catalog is the no-DAC form, also written Mod GRF (1-29). Check the observed mass on the certificate rather than the name on the label, here more than anywhere except TB-500.
