Description
The Syn-Coll 200mg vial is supplied as a palmitoylated tripeptide, INCI name Palmitoyl Tripeptide-5, freeze dried and sealed. The fill weight is 200 mg of net peptide content. The cake is white to off-white. Every figure quoted on this page comes from the certificate issued against the lot number on the vial. For laboratory research use, and not for human or veterinary consumption.
The same material is catalogued elsewhere as Palmitoyl Tripeptide-5. The label on the Syn-Coll 200mg vial carries the compound, the fill weight and the lot number, and that is the extent of it.
What the Syn-Coll 200mg vial is
Everything that can honestly be said about the Syn-Coll 200mg vial before the certificate is opened is listed below.

| Form | Lyophilized, white to off-white, sealed under vacuum |
| Sequence length | Three residues plus the acyl group |
| Purity | HPLC, percent of total peak area |
| Identity | Mass spectrometry against expected mass |
| Water | Karl Fischer titration, percent by weight |
| Documentation | Independent certificate of analysis, tied to the lot number |
| Price basis | About $1.04 per milligram as priced |
| Supplied for | Laboratory research use only, not for human or veterinary consumption |
Why it is a powder, and what a milligram of the Syn-Coll 200mg vial costs
Peptides are shipped dry for a simple reason: in solution they degrade, and nobody can control the temperature of a parcel in transit. Freeze drying removes the solvent under vacuum and leaves a solid with a low residual water figure, which the certificate states. The cake that results is physically fragile and can break loose and rattle. A broken cake is cosmetic. The number that matters is the fill weight. Nothing about the Syn-Coll 200mg vial is sold by volume.
Doing the division
Milligram content is the unit the Syn-Coll 200mg vial is sold in, because it is the only figure that makes two listings comparable. The quotient is close to $1.04 per milligram. Keep two things in view when you use it: the fill weight it was divided by, and the assay percentage from the certificate, because the second tells you how much of that fill is the named compound. Compare the Syn-Coll 200mg vial on that basis rather than on the price of the glass. The case is made at greater length in why price per milligram beats the price on the bottle.
What the certificate of analysis reports
The certificate is the product description that actually counts. It names the compound and the lot, gives the date the work was done, prints the purity percentage and the trace it was integrated from, records the measured mass beside the expected mass, states the water content, and identifies the laboratory. If you only ever read one thing on this page, read that document. The certificate issued with the Syn-Coll 200mg vial is specific to the lot and not to the product line.
Assays are run by an outside contract laboratory rather than in house. Independence of that kind matters, and it has a limit: the figure still depends on the sample that was submitted, which is why lot by lot testing rather than periodic testing is the part that matters. Stock is withdrawn from sale where the certificate for the Syn-Coll 200mg vial does not support the figures here. See how to read a certificate of analysis and check the lab before you check the numbers.
Behind the figures
HPLC provides the purity percentage. The method resolves a mixture into its parts on a column and the detector reports them as peaks whose areas are integrated. Purity is the main peak over the sum of all peaks. Because it is a ratio, two lots can share a purity figure and still differ in fill weight, which is why both numbers are published and neither substitutes for the other. The same methods are run on the Syn-Coll 200mg vial as on every other lot on this shelf, and formulae and expected masses for compounds of this class can be checked through PubMed.
Naming, abbreviations and storage
Naming is inconsistent across the whole category. Research groups issue internal codes, cosmetic registers assign INCI numbers and renumber them, regulators grant nonproprietary names, and vendors invent their own. Several abbreviations on this shelf unpack into descriptions of activity. They are not unpacked here, and where a compound cannot be described without that, only its measurable properties are described. The catalogue name carried by the Syn-Coll 200mg vial is the one the trade uses, and a trade name is not an identifier.
Sealed, cold, dark and dry. Short term storage at refrigerator temperature and long term storage at minus 20 degrees Celsius or colder are the standard conditions for lyophilized peptide material of this kind. Keep the certificate with the vial, since the lot number is the only thing joining the two.
Research use only, and what this page will not tell you
Sold to qualified purchasers for laboratory research only. Not for human or veterinary use. The page carries no dosing information, no protocol, no administration instructions and no account of physiological activity, because publishing any of those would be describing a use this material is not sold for. We will not supply them privately either. No part of this page describes a use for this material in a person or an animal. Bacteriostatic water, sterile diluents and syringes are stocked separately rather than sold as a set with the vial.
Two things are true at once. This is sold as a laboratory reference material, and that sentence on its own settles nothing, because a page that describes effects, timing or quantities for a person is describing a use whatever the footer says. See research use only is not a legal strategy.
Lots that failed their own stated figures are kept rather than deleted, which is the point of an archive as against a highlight reel. This item sits on the cosmetic peptide shelf, inside the research peptide catalogue, and every certificate we hold is on the lab results page.
