CJC-1295 (no DAC) & Ipamorelin from Ipamorelin Labs is a two-peptide research blend (Mod GRF 1-29 and ipamorelin, equal parts) designed for activity at the GHRH receptor (CJC-1295 no DAC) and ghrelin receptor GHSR (ipamorelin), supplied as a white lyophilized powder in 10 mg and 20 mg vials. Every lot is independently tested, and its results are published as a lot record with the certificate PDF.

Specifications and current testing status in one place.
Ipamorelin is a five-residue synthetic peptide, Aib-His-D-2Nal-D-Phe-Lys-NH2, that acts at the ghrelin receptor (GHSR). Three of its five residues are non-standard: α-aminoisobutyric acid, D-2-naphthylalanine and D-phenylalanine, which together make the short chain resistant to proteases. At 711.87 g/mol it is a compact molecule that separates easily from larger peptides on HPLC.
On Klow.bio, ipamorelin is supplied in equal parts with CJC-1295 without DAC, in 10 mg and 20 mg vials at $53.99 to $89.99. Lot KB80923 measured 5.08 mg ipamorelin alongside 5.45 mg CJC-1295, at 99.72% overall purity with both identities confirmed by LC-MS.
The two peptides are very different in size: Mod GRF (1-29) is 3367.95 g/mol and ipamorelin 711.87 g/mol, so they separate cleanly on HPLC and are quantified individually. Ipamorelin contains three non-standard residues (Aib, D-2-naphthylalanine and D-phenylalanine).

Store sealed, dry and protected from light at the temperature stated on the vial label. Allow a cold vial to reach room temperature before opening. Lyophilized material absorbs moisture from the air, and absorbed moisture restarts the reactions that drying slows, so keep vials sealed until needed. Storage and stability guide.

Ordering and shipping. CJC-1295 (no DAC) & Ipamorelin is sold through klow.bio, operated by Klow Labs LLC. Orders ship the next business day. Same-day cutoff is 4:00 PM CT, with overnight and 2-day options at checkout. See shipping and returns.
All testing is performed by Freedom Diagnostics, an independent laboratory, on every lot.
Reversed-phase high-performance liquid chromatography separates the sample's components by hydrophobicity, and a UV detector records each as a peak. Purity is the main peak's area as a percentage of all detected peak area.
Limits: does not identify the peak, and impurities that co-elute or absorb weakly in UV can be under-counted. More on HPLC
The separated sample enters a mass spectrometer via electrospray ionization, which gives the molecule one or more charges.
Limits: confirms molecular weight, not amino-acid order.
The laboratory quantifies the main compound in the tested vial against a standard. It is reported in milligrams next to the labeled vial size.
Limits: measured on the vial tested; other vials from the same lot are expected to be similar but are not individually measured.
