Could this be combined with PDRN lypholisised Powder as a spicule treatment serum? I know that there's evidence of efficacy of topical EGF, but as a matter of fact the molecular weight is very high, so a monthly or biweekly treatment with spongilla spicules to enhance penetration might be a good idea, but I am not sure due to the fragility of growth factors. And could that be incorporated with PDRN together? Please take your time to answer, I know you are very busy and thank you in advance for your sharing your knowledge freely, I learned so much from the archived answers on this website!

Please recommend an emulsifier for **Clear Whey Protein** in powder form to reduce clumping and improve water dispersibility. I am currently using `polydextrose` and `inulin`, but are there any other recommended ingredients? The clear whey I use is fat-free, clumps easily, and produces a lot of foam. I would like to: * Reduce shaking time * Reduce clumping * Reduce foam formation This is to increase the ease of use for the product. However, if the ingredient causes turbidity (cloudiness), I may only be able to use it in small amounts. Thank you.
