Why weekly, and why only changes

Our price capture reads product pages once a week and appends what it finds to a history that is never edited. A daily email would repeat the same readings; a "deals" email would need someone to decide what counts as a deal. Instead the report is a diff: if a price moved, it is in; if it didn't, it isn't. Partners and non-partners are listed on the same terms, and where a partner code applies it is printed beside that vendor's line with the disclosure. If you want alerts for one compound only, every compound ranking has a price-drop alert form for just that compound.

Questions

How often does it go out?

Once a week, Friday morning US time. Our price capture runs weekly, so a daily email would have nothing new in it. If a week has no changes, the email says so in two lines and stops.

What is in it?

Only what changed, with dates: every price move on the listings we track (vendor, compound, size, old price, new price), listings that sold out or came back, rubric score changes with the reason, and certificates of analysis we opened that week. It is generated from the same append-only price and score history the site prints, so nothing in it is typed for the email.

Do partners get better placement?

No. The report lists every move at every scored vendor, partner or not, in order of size. Where we hold a partner code it is printed next to that vendor's line, and the affiliate relationship is disclosed in every issue.

Will you sell or share my address?

No. The list lives with our email provider and is used for this report only. Every issue carries a one-click unsubscribe. See the privacy policy.

Is this medical advice or a recommendation to buy?

No. Research peptides are sold for laboratory use only. The report records prices and documentation; it does not recommend any compound for any purpose.
