Sermorelin

Growth-hormone secretagogue Limited evidence 3 cited studies 62 live vendors

Sermorelin is a synthetic peptide corresponding to the first 29 amino acids of growth-hormone-releasing hormone (GHRH), the fragment characterized in research as the active core of the parent molecule. In laboratory research it is classified as a growth-hormone secretagogue and studied as a GHRH analog that acts on pituitary GHRH receptors in laboratory models. This page tracks research-use-only (RUO) vendor pricing for Sermorelin so researchers can compare cost per milligram across suppliers; it is not intended for human or veterinary use.

Evidence brief

Sermorelin is a growth-hormone-releasing hormone (GHRH) analogue (the first 29 amino acids of GHRH) historically studied as a diagnostic agent and as a treatment in growth-hormone-deficient children.

Computed from 75 in-stock listings across 62 sources we captured first-party, with bulk vials, blends and statistical outliers excluded so the figures compare like with like. The spread is the highest tracked price divided by the lowest — how much the same milligram varies depending on where you look. The chart is the daily minimum; days we did not capture are left out rather than filled in.

▸ Why compare $/mg for Sermorelin?

Per-milligram prices for Sermorelin vary widely because vials are sold in different peptide masses (commonly 2 mg, 5 mg, or 10 mg), and larger vials usually lower the effective $/mg, while listed weight may reflect net peptide or gross salt/acetate content. Synthesis scale, stated HPLC purity, lyophilization quality, and shipping or cold-chain handling also differ between vendors, so normalizing to $/mg is the only reliable way to compare like with like.

▸ Reading the COA

For Sermorelin, a certificate of analysis should confirm identity by mass spectrometry against the expected monoisotopic mass for the 29-residue GHRH(1-29) sequence (molecular formula around C149H246N44O42S, roughly 3358 Da), and report HPLC purity, with many research suppliers listing 98%+ as a common threshold. Check that the reported net peptide content matches the labeled vial mass, since acetate salt and residual water can inflate gross weight. Watch for truncated or deletion sequences and deamidation byproducts in the HPLC trace, which are typical impurities for peptides of this length. A COA is about verifying the identity and purity of the material, not about any outcome.

▸ FAQ

How is lyophilized Sermorelin typically stored and handled as a research material?
As a lyophilized (freeze-dried) powder, research peptides like Sermorelin are generally kept sealed, desiccated, and protected from light, with cold storage such as -20C or lower commonly cited for longer-term material stability. Repeated warming and exposure to moisture or air can degrade peptide material, so vendors and labs typically minimize freeze-thaw cycles. This is general material-handling and storage context for a research-use-only material only, and is not use guidance.
What is a certificate of analysis (COA) and what should I look for on one for Sermorelin?
A COA is the supplier's analytical document verifying what is in the vial. For Sermorelin, the key items are identity confirmation by mass spectrometry against the expected GHRH(1-29) mass, an HPLC purity value (often reported at 98% or higher), and net peptide content versus the labeled weight. A complete COA also notes the analytical methods and lot number so results can be tied to the specific batch you received.
Why do per-mg prices for Sermorelin differ so much between vendors?
Differences come from vial size (bulkier 5 mg or 10 mg vials usually reduce $/mg versus 2 mg vials), stated purity grade, synthesis scale, and whether the listed mass is net peptide or gross salt-inclusive weight. Cold-chain shipping, lot testing depth, and how much third-party analytical documentation a vendor provides also factor into the price, which is why normalizing to cost per milligram is useful.
