Research & reference information

This profile compiles research and community-sourced reference information for educational purposes. Information may evolve as research and community knowledge develop. It is not individualized medical advice.

Overview

A diluent used to mix up IGF-1 family peptides.

It’s a solvent, not a peptide.

Don’t inject it on its own.

What It Does

0.6% sterile acetic acid solution, the required solvent for IGF-1 LR3 and similar peptides that don’t dissolve in BAC water.

IGF-1 family peptides have isoelectric points near neutral pH and aggregate or precipitate in BAC water.

Reconstitution Calculator

Enter the vial amount and diluent volume to calculate concentration. If you already have a target amount, you can also convert it to liquid volume and syringe markings. This tool does not recommend a target amount.

Calculated concentration—Enter both values above.
Optional conversion

Enter a target amount you already have and select the syringe capacity.

Calculated draw—Enter concentration inputs and a target amount.

Mathematical reference only. The calculator does not determine an appropriate target amount. Syringe capacity only changes the maximum volume that fits.

Handling & Stacking

Injection site
Solvent only, never inject undiluted acetic acid. Reconstitute peptide first, then dilute with sterile saline 1:1 immediately before injection.
Storage
Room temperature. Single-use ampoules preferred over multi-dose vials. Check for cloudiness before use.
Side effects
Injection-site sting (acidic pH). Tissue irritation if injected undiluted.
What to expect
Slight sting at the injection site is normal due to the acidic pH. Always dilute with sterile saline before injecting if possible.
Pairs well with
IGF-1 LR3, IGF-1 (Standard); required solvent. Sterile saline, dilute 1:1 before injection.
Avoid
Direct injection without dilution. Peptides that prefer BAC water (almost all peptides except IGF-1 family).

Safety & Patient Education

Warnings
Solvent only; never inject undiluted (causes burning, tissue irritation)
Labs
Compound-specific: CBC + CMP baseline; no compound-specific markers routinely required
Patient education
Always dilute with sterile saline before injection
