Pinealon 20 mg

What is Pinealon?

Pinealon is the tripeptide glutamyl-aspartyl-arginine from the Khavinson short-peptide bioregulator series, studied in neuronal and cerebral-cortex research. Like the rest of the series, most of its literature comes from one research group, which is worth noting when citing it. Pepstral supplies it as a lyophilized powder for in-vitro laboratory research only.

What is Pinealon studied for?

• Neuronal tissue research models
• Short-peptide bioregulator comparisons
• Oxidative-stress protection assays
• Gene-expression studies in ageing models

All applications above are in-vitro or preclinical research contexts. Pinealon is sold for laboratory research only and is not for human or animal use.

What does the certificate for lot PINE20-0803 show?

Every lot of Pinealon is tested by an independent US laboratory before it is listed. The report for lot PINE20-0803 is in the COA library and the lot number printed on the vial matches it. The current results:

Test	Method	Lot PINE20-0803 result
Identity	LC-MS/MS	Pinealon · conforms
Content	HPLC quantitation	20.80 mg
Purity	RP-HPLC (214 nm)	99.68%
Endotoxin	USP <85>	<0.05 EU/mL
Heavy metals	USP <232>	<0.01 ppm

How is Pinealon handled and stored?

Sealed vials are stored at -20°C away from light and keep for 24 months. To reconstitute, add bacteriostatic water slowly down the inside wall of the vial and swirl until clear; never shake. Once in solution, keep at 2 to 8°C and use within our 28-day default for a preserved solution. The concentration table gives the dilution volumes and microlitre aliquots for this vial.
