Overview
About P21 (P021).
P21 (P021) is a synthetic CNTF-mimetic peptide in which the DGGL active fragment (ciliary neurotrophic factor residues 147–150) is capped with an adamantylated amino acid to improve metabolic stability and lipophilicity. In published animal studies it has been characterized as a neurotrophic/neurogenic agent reported to promote hippocampal neurogenesis and synaptic plasticity; all references here are to non-clinical laboratory research only.

FAQ
P21 (P021) — frequently asked by B2B buyers.
What is P21 (P021) and in what format is it supplied?
P21, also designated P021, is a CNTF-derived adamantane-modified neurotrophic peptide (Ac-DGGLAG-NH₂) supplied strictly for research and manufacturing use. Pepti stocks it as lyophilized powder in 5 mg vials; other fill weights and bulk quantities are available on RFQ.
What are the confirmed specifications and CAS number?
P021 corresponds to CAS 1246751-68-7, molecular formula C₂₇H₄₂N₆O₈, and a molecular weight of approximately 578.7 g/mol. Its core sequence is Ac-DGGL- with an adamantylated glycine residue, capped as the C-terminal amide (Ac-DGGLAG-NH₂). Batch-specific values are documented on the COA.
What quality documentation ships with each batch?
Every batch is released with a Certificate of Analysis reporting HPLC purity, mass-spec identity confirmation, appearance, and moisture/residual-solvent data as applicable. TDS, SDS, and additional supporting documents can be provided on request for qualified B2B accounts.
What is the MOQ and how does private-label / OEM work?
Minimum order quantity is 50 kits (500 vials) at the 5 mg size. Pepti offers OEM/private-label service including custom labeling, vial and fill-weight configurations, kitting, and branded documentation. Share your specification for a formal quotation and lead time.
How should P21 be handled and stored, and what are the compliance terms?
Store lyophilized powder at -20°C, protected from light and moisture; ship under cold-chain / ice-pack conditions. P21 is offered for laboratory research and manufacturing use only — it is not a medicinal product and is not supplied for consumer or veterinary consumption, diagnostic, or therapeutic use.
