Like Viperspit said, they are propietary blends as well, but here is some other info for you. Obviously you are able to use any products that you feel comfortable with, and thats what I would suggest! Your happiness is most important right!
Restore:
Likely the most powerful and effective DHEA analog is b-AET (beta-androstenetriol). It has been shown in studies to be between 100 and 100,000 times more active than its DHEA precursor metabolites. However, like most DHEA analogs there is the issue of poor oral bioavailability. By supporting the delivery value through simple alkylation, MbAET is nearly 100% orally bioavailable and only takes a few milligrams to do its job.
TX:
Beta-AET ECPE inhibits the 11b-HSD-1 enzyme both locally and systemically. This means that there is less conversion of cortisone to cortisol in muscle as a result of training and everywhere else due to stress like dieting. Based upon the studies, it appears that in mediating this pathway, bAET ECPE increases immune function and recovery of cells as well. Add this to its stimulatory affect upon the thyroid gland to support natural thyroid hormone production? Yup, less cortisol, higher metabolic rate, inhibition of that nasty negative thyroid hormone production feed-back loop…less fat, more lean muscle and positive support to health. Not bad!
Retain:
MbAET: b-AET (beta-androstenetriol). It has been shown in studies to be between 100 and 100,000 times more active than its DHEA precursor metabolites. MaET’s mission is to seek out and control cortisol enzymes. There are two enzymes that are able to make each of these convert into the other. One of them is not your friend and that is where MbAET has your back.
11b-HSD-1: Converts inactive cortisone into cannibalistic cortisol. Studies have implicated this event in fat tissue as a pathway for increased fat storage. Part of the reason GH has a positive affect upon body composition is through its ability to inhibit 11b-HDS-1
11b-HSD-2: Converts nasty cortisol into cortisone. 11betaHSD2 debulks intracellular cortisol by 90%. (Let the 11b-HSD-2 rule the house)
MbAET inhibits the 11b-HSD-1 enzyme both locally and systemically. This means that there is less conversion of cortisone to cortisol. Based upon the studies it appears that in mediating this pathway, it increases immune function and recovery of cells as well. Less cortisol and fat, more lean muscle and positive support to health. Not bad!
As far as the versions used in each, The TX version also acts as a stimulant & increases immune functions. Methylated products are, well some worse than others for sure, these are mild and have not caused any issues, esp when used for short term, short term being anything under 12-16 weeks.
