Epithalon (Epitalon) vs Pinealon
At 10mg, the only strength both are offered in, Pinealon is the cheaper per mg: $0.405 per mg against $0.584 (PL10 in 50-box lots, ET10). By the single box, Epithalon is the only option, from $0.468 per mg at 50mg (ET50); every Pinealon line is special order. Epithalon is offered in 2 strengths (10mg to 50mg), Pinealon in 3 (5mg to 20mg); Epithalon has 1 on the shelf today, Pinealon none (special order, 50-box minimum). The least either takes: one box of ET10 at $58.42, two for a first order’s $100 minimum, against 50 boxes of PL5, $1,310.00 of goods.

What differs between Epithalon and Pinealon
A tetrapeptide, Ala-Glu-Asp-Gly, against a tripeptide, Glu-Asp-Arg, both from the same line of work on pineal extracts, both with nothing to oxidise. Epithalon’s Asp-Gly pair can rearrange to isoaspartate, the related substance to ask the desk about; Pinealon has no such motif. Both are short and extremely soluble in water. Masses 390.4 and 418.4.

Questions
What is the difference between Epithalon and Pinealon?
A tetrapeptide, Ala-Glu-Asp-Gly, against a tripeptide, Glu-Asp-Arg, both from the same line of work on pineal extracts, both with nothing to oxidise. Epithalon’s Asp-Gly pair can rearrange to isoaspartate, the related substance to ask the desk about; Pinealon has no such motif.
What are the molecular weights of Epithalon and Pinealon?
Epithalon 390.35 and Pinealon 418.41, 28.06 apart. In electrospray the [M+H]+ ions come near m/z 391.4 for Epithalon and 419.4 for Pinealon on an average-mass reading, and at 391.146 and 419.188 at high resolution.
Which carries more negative charge, Epithalon or Pinealon?
Epithalon: its glutamate and aspartate have no basic side chain to offset them, so its charge comes to about -2 at neutral pH, and, small and acidic as it is, it also ionises in negative mode, [M-H]- at m/z 389.131. Pinealon carries the same Glu-Asp pair but ends in arginine, strongly basic, so it is a zwitterion with one negative charge to spare.
Which is cheaper per mg, Epithalon or Pinealon?
At 10mg, the only strength both are offered in, Pinealon is the cheaper per mg: $0.405 per mg against $0.584 (PL10 in 50-box lots, ET10).
Which comes in more strengths, Epithalon or Pinealon?
Pinealon, with 3 against 2. Every strength is a separate line with its own code, price and stock state.
Are Epithalon and Pinealon made to the same specification?
Yes: both are supplied to purity not less than 98.0 percent by RP-HPLC and net content within 5 percent of label, and each certificate reports those with a measured mass, matched to the calculated figure on each sheet. The retest date is on the batch record. What differs is each molecule’s own chemistry, described on its compound page.
