Unfortunately, this can sometimes happen with HGH Frag, even when the peptide has been reconstituted correctly.
This is related to its physicochemical properties. HGH Frag (fragment 176–191) contains certain regions of the peptide chain that can interact with each other in solution. Under certain conditions, this can cause the solution to become thicker or develop a gel-like consistency.
There are several reasons why this may occur:
1. Rapid cooling after reconstitution
If the vial is placed in the refrigerator immediately after reconstitution, especially in the coldest part of the fridge, the temperature of the solution drops quickly. At this point, the peptide chains can partially fold and interact with each other, which creates the gel-like effect. If the storage temperature is too low (below ~3–4°C), this can increase the likelihood of this happening.
2. High concentration of the solution
When the peptide is reconstituted with a small amount of water, the concentration becomes higher, which increases the chance of peptide chains interacting with each other. We usually recommend purchasing additional bacteriostatic water and reconstituting with 3 ml.
To reduce the chances of this happening, we usually recommend:
• After reconstitution, allow the solution to sit at room temperature for 5–10 minutes
• Store the vial in the refrigerator door, where the temperature is usually 4–6°C, rather than in the coldest part of the fridge.
And of course, the vial that turned into gel will be replaced for you this time.
