VIP 10mg

Pepta Labs sells VIP for laboratory research as a single 10 mg vial of lyophilized powder on this page, with free US shipping and the analytical report available by email before you order. Orders are placed from a registered account, and the buyer certifies research use at checkout.

No. VIP 10mg is the only VIP listing, so every VIP vial Pepta Labs ships holds the same supplier-stated 10 mg. Larger quantities are ordered as several 10 mg vials in one order; the pack options are shown on this page.

A supplier-stated 10 mg of lyophilized VIP powder in a sealed glass vial. VIP is typically supplied as a trifluoroacetate or acetate salt, so the stated 10 mg is the weight of the dry powder as supplied, which can include a counter-ion and residual water, not net peptide content. Net peptide content is not reported per listing, vial fill-quantity testing is not claimed, and the vial carries no lot number.

The CAS 37221-79-7 record is drawn with a free C-terminal carboxylic acid, but the C-terminally amidated form of the same 28-residue sequence is also commonly supplied. To see which form the sampled production run was, compare the observed mass in the report with the calculated values, about 1 Da apart (3326.8 g/mol for the acid, 3325.8 g/mol for the amide). The Learn guide on peptide sequence notation explains what the -NH2 suffix means.

Request it on this page or email support@peptalabs.com with the compound name, and the report is sent by email, before you order if you prefer. It covers the production run that was sampled, not an individual vial: purity is RP-HPLC area-percent and identity is by mass spectrometry. The Learn guide How to Read and Verify a Peptide Certificate of Analysis walks through each section.

Keep the sealed vial of dry powder at 2-8 C for short-term storage or at -20 C for long-term storage, protected from light and moisture. VIP contains one methionine and two tyrosine residues, which are prone to oxidation; methionine oxidation shows up as a +16 Da peak in mass spectrometry. The Learn guide Storage Temperature and Handling of Lyophilized Research Peptides covers dry-powder storage in more detail.

VIP 10mg starts at $48.09 per vial. 3-vial packs are 10% off and 5-vial packs are 15% off. US shipping is free with no minimum.

Pepta Labs accepts Cash App, Venmo, Zelle, Bitcoin and Ethereum (5% crypto discount). Payment instructions are emailed as soon as you place your order.

No. VIP 10mg is offered solely for laboratory research and is not for human or animal use, consumption, administration, diagnosis or treatment. Buyers certify this at checkout.

VIP is a 28-residue linear peptide. The CAS 37221-79-7 record (free C-terminal acid) has formula C147H237N43O43S and average molecular weight 3326.8 g/mol; the C-terminal amide form is C147H238N44O42S at 3325.8 g/mol. On electrospray mass spectrometry the peptide is normally observed as multiply charged ions, for example [M+3H]3+ near m/z 1109 and [M+4H]4+ near m/z 832.

Yes. The 28-residue sequence is identical in humans, pigs and rats, so a single synthetic peptide with CAS 37221-79-7 covers all three designations.

It is the Chemical Abstracts Service registry number for the 28-residue VIP sequence. Salt form, vial quantity and purity grade are not part of the CAS identity.
