Of particular relevance to IGF-1 anabolic research are TSC2 (relieving inhibition of mTORC1, driving protein synthesis) and FoxO transcription factors (inhibiting their nuclear translocation, blocking expression of atrogenes like MuRF1 and atrogin-1 that drive muscle protein breakdown)
Mutations in CPT1 can cause carnitine palmitoyltransferase I (CPT I) deficiency, which is an autosomal recessive genetic condition (need two copies of the mutation)
Molecular regulation of fatty acid -oxidation extends beyond core enzymatic machinery (CPT1, CPT2) to include sophisticated transcriptional and post-translational control mechanisms involving AMP-activated protein kinase (AMPK), peroxisome proliferator-activated receptor (PPAR), and peroxisome proliferator-activated receptor coactivator-1 (PGC1) (23, 4244)
Puritans Pride does claim that all of its supplements are tested or inspected up to 15 times during manufacturing, but without the involvement of an independent third party, theres no way to know the details of this testing
