The only minor disagreement I have is that protein accretion is the same between, say, nandrolone versus say Dbol. It's not. That is, despite the lack of a research method being used in humans as precise as in rats to distinguish the effect of androgens on muscle protein synthesis/breakdown (e.g., arteriovenous balance techniques) given the impracticability of this in human research on long time frames, direct measures of MPS (muscle protein synthesis) & MPB (breakdown) are not representative of AAS-induced muscle anabolism to begin with.
This is because AAS/androgens primarily cause muscle protein accretion by modulating glucocorticoids and increasing cellular (mIGF-I) IGF-I activity (this is often mediated by secondary messenger systems like Akt, Notch, etc.), by aromatization (which stimulates GH secretory-burst mass and, thereby, elevates the incremental and absolute height of serum GH concentration causing increased IGF-I levels), and by ligand-dependent and -independent AR action that exerts (only) some action via classical mRNA-mediated translation (protein synthesis) as well as rapid nongenomic action. The differences between AAS in the activity of these mechanisms belies necessary differences in protein deposition between androgens.
The complexity and diversity of AAS action in promoting muscle protein accretion defies Victor's apparent focus on muscle protein synthesis and degradation (protein turnover) with rodent studies.
Besides, the nitrogen excretion/balance studies (e.g., comparing Deca > Primo > Dbol above), more recent research using DXA to measure T-induced hypertrophy, and feed efficiency with tren that we do have ARE representative of improved protein balance, despite Victor's myopically focusing on the relevance of impracticable protein turnover measures, which apply to other anabolic agents like IGF-I and its analogues far more than AAS, given androgens' diversity of action across different pathways for inducing muscle protein accretion.
I tremendously respect you both
@LATS and
@b-boy - I just take issue with the consequences that might arise (guys believing tren and mast are equipotent in muscle anabolism) as well as the speed at which the view that all AAS accrue muscle tissue equally has promulgated.
