Description

DSIP is a nine-amino-acid peptide isolated in the seventies from rabbit brain during slow-wave sleep, which is where its name comes from. The literature studies it in sleep architecture, delta-wave, circadian and stress-hormone models. It is our least expensive vial and it carries exactly the same paperwork as the most expensive one: HPLC and mass spectrometry per lot.

Sold strictly as a reference material for laboratory research. We do not provide dosing information or administration instructions.

Purity & certificate

Every lot is tested by an independent laboratory using HPLC and mass spectrometry. The lot in stock right now is BV-2408-DSP15.

The certificate reports four things: identity, purity, water content and the absence of residual solvents. If any of the four is missing, the document is incomplete.

We send it in the WhatsApp thread before you pay, and it is worth knowing how to read it: how to read a COA.

Handling & storage

The vial arrives sealed and lyophilized. Refrigerate it on arrival; for long holds, keep it frozen and away from light.

Handle it under laboratory conditions only. We do not supply reconstitution instructions, dosing information or injection supplies of any kind.

Shipping & returns

Confirmed before 2pm ET on a business day, it leaves the same day. Two to four business days across the continental US, with tracking. Flat $12, free over $200, in a plain box with nothing printed about the contents.

Unopened vials can be returned within 14 days of delivery. The full terms are here: shipping policy.

The cheapest vial on the site and it came with the same paperwork as the expensive ones. That told me everything.

Questions

Ordering, payment and shipping

How do I pay?
You build your cart here and confirm the order. That creates a numbered order and opens WhatsApp with the details already written. Payment is by Zelle, and we send the confirmation with your tracking number.
Why WhatsApp instead of a card?
Research compounds sit in a category most card processors decline. Rather than run a checkout that fails at the last step, we confirm each order by message. It takes about a minute and nothing gets declined.
How long does shipping take?
Orders confirmed before 2pm ship the same day, the rest the next business day. Inside the US, delivery is typically 2 to 4 business days with tracking.
Is the packaging discreet?
Plain outer box, no branding and no product names on the label. Inside, each vial is protected and packed with a cold pack when the compound needs it.
Where do I find the COA for my lot?
On the product page, above the buy button, with the lot number next to it. If you already received a vial, type its lot into the search and you will land on the same certificate.

Start with the certificate, not the price

Open any product, read its COA, then decide. That is the order we would want if we were buying.
