Peptide blends vs separate vials: GLOW, KLOW and research sets explained

A peptide blend is two or more compounds premixed and lyophilised together in one vial. A research set is two or more compounds supplied in separate sealed vials. The contents can look similar on paper, but the format changes how the material is identified, documented and handled. This guide explains the difference and lists what each Ascend Research blend contains.

Blend or set: what is the difference?

Premixed blend Research set or duo
Vials One Two or more
Ratio of compounds Fixed at manufacture Each compound is separate
Labelled quantity Total across all compounds Stated per vial
Listing prefix [1V] [2V] or [3V]

What do [1V], [2V] and [3V] mean?

The bracketed prefix in a listing title is the number of vials supplied. [1V] is a single vial, which for a multi-compound listing means a premixed blend. [2V] and [3V] are sets of two or three separate vials. Listings that say “separate vials” are never premixed.

What is in the GLOW blend?

Glow Blend 70mg is one vial containing three compounds premixed to 70mg in total:

  • GHK-Cu 50mg
  • BPC-157 10mg
  • TB-500 10mg

What is in the KLOW blend?

Klow Blend 80mg is one vial containing four compounds premixed to 80mg in total. It has the same three compounds as GLOW plus KPV:

  • GHK-Cu 50mg
  • BPC-157 10mg
  • TB-500 10mg
  • KPV 10mg

GLOW vs KLOW at a glance

Compound GLOW 70mg KLOW 80mg
GHK-Cu 50mg 50mg
BPC-157 10mg 10mg
TB-500 10mg 10mg
KPV Not included 10mg

Which other blends and sets are listed?

All multi-vial listings are grouped under research sets.

What should you check before choosing a format?

  • Whether your work needs each compound on its own or in a fixed ratio.
  • Whether the stated quantity is a total for the vial or an amount per vial.
  • What the documentation for the batch covers. See the COAs page.
  • That each vial label names every compound it contains.
