He mixelflic,
what do you think about alri pro anabol edycsterone product?
Tough call in a multi-ingredient product, but here are my thoughts on the Ecdy component.
It's true rubrosterone lacks the classic "tail", associated with the 476 Ecdy's thus identified (1) Please see Rubrosterone vs. Turkesterone chemical graphic below. Rather stark when you see it for the first time. Rubrosterone is nothing new though, first being identified in 1968(2). Japanese researchers have studied it, and found 7-keto DHEA 60% as anabolic.(3) I'm a bit confused as to the focus on the androgen receptor, as previous studies (done both in the West and Russia) have found no AR binding. A study (4) performed just this year validated its anabolic properties, called for it being put on the banned list but the study headline was what grabbed all the attention..
Estrogen receptor beta is involved in skeletal muscle hypertrophy induced by the phytoecdysteroid ecdysterone

For the record, I think its interaction with the estrogen receptor doesn't explain its pro-hypertrophic effects. Rather, a combination of mechanisms is responsible. Given the broad range of benefits Ecdy conveys in mammals, there must be at least 1 cascade mechanism in play. When I wrote The Blueprint in 2009, I theorized that Ecdysterone worked via the PI3K/AKT pathway. Subsequent research carried out at Rutgers has confirmed this (5).
Abstract
"Phytoecdysteroids, structurally similar to insect molting hormones, produce a range of effects in mammals, including increasing growth and physical performance. In skeletal muscle cells, phytoecdysteroids increase protein synthesis. In this study we show that in a mouse skeletal muscle cell line, C(2)C(12), 20-hydroxyecdysone (20HE), a common phytoecdysteroid.... elicited a rapid elevation in intracellular calcium, followed by sustained Akt activation and increased protein synthesis. The effect was inhibited by a G-protein coupled receptor (GPCR) inhibitor, a phospholipase C (PLC) inhibitor, and a phosphoinositide kinase-3 (PI3K) inhibitor."

DISCLAIMER: This is my opinion, and I have NOT used the product yet. I don't speak definitively, to things I haven't used. So I'll keep an open mind, as to ALRI's product...
