IGF-1 LR3 and DES Blood work testing

[gear shef]

Got a question for some of you who may be knowledgeable on peptides.

With GH for those of us that have used it may opt to have blood work on it in an attempt to validate its legitimacy.

Is it possible to do this with IGF LR3 and DES. Now I know you can have IGF levels tested but what I also know is that most sold are not human receptor grade or DNA recombinant synthesized.

So if you were using some b.s. Rat igf that a research company sold you, which isn't going to provide benefit. Would it show a....for lack of better term "false" high IGF level in a humans blood?

No one?

That's an simple question with a COMPLEX ANSWER and here's a few reasons why.

SIZE MATTERS!
- bc PEPs are relatively small molecules with amino acids linked in a SPECIFIC sequence
they can be difficult to "detect" especially on a quantitate (concentration) basis
- PEP AA sequencing and "linkage" can have a considerable influence on their "polarity", which can alter their chromatographic elution times and intervals
- NOT ALL "GHRP-2" are created equal and this becomes apparent when comparing the different MOLECULAR WEIGHTs of "GHRP-2" as listed by UGL manufacturers
(I've noted a variance of as much as 90 daltons for GHRP-2 alone)

For those reasons (and many others) the most reliable initial step in evaluating a PEP would be a MASS SPEC ANALYSIS and the second would be AMINO ACID sequencing assay.

ALL told you're looking at forking over close to $5OO bucks for a bottle of a product that costs FIFTY!

One could also assay IGF-1 levels, however bc IGF levels varies considerably on an individual basis, and bc PEPs have not been shown to increase IGF-1 within the supra-physiologic range, I doubt the info obtained is actionable from a qualitative or quantitative perspective.
