Im going to start doing this with my HGH and see if it helps with sides. It definitely should! Thanks my brother!
It may.
Of course no study intentionally injecting humans with high impurity HGH would ever be authorized, but we know aggregates induce a stronger immune response.
We know that certain conditions encourage and speed up the formation of aggregates.(think "crystallization" in terms of how aggregates start with a tiny "seed" and grow from there).
There was a study comparing numerous forms of somatropin. From single use vials, to multi use vials, to pre-reconstituted pens.
For what it's worth, in the FDA database that tracks reports of side effects, the single use vials that are used immediately after reconstitution had the fewest sides reported. The pens had the highest, To me, that suggests aggregates play a role, since they form after reconstitution, and immediate single use vials spend the least time in reconstituted form, developing the fewest, smallest aggregates.
From my own experience with Tesa, perhaps one of the most aggregate prone peptides out there, even from pharma, after filtering, the first dose is PIP free, but by the 5th and final dose, the PIP, lumps, and redness has returned almost to the pre filtration level. So in that case, I keep the entire 3ml in a syringe with filter attached, and backfill an insulin syringe for each dose. This "per dose" filtration (a technique practiced in Europe called 'bedside filtration') has eliminated PIP for every dose.
