A-Rod’s Advanced Drug Regimen

Although Alex Rodriguez finally waived the flag of surrender and dropped his lawsuit against the MLB for suspending him, we have learned quite a bit about the evidence the league had on the star player’s use of performance enhancing drugs.

Alex Rodriguz’ PED program created by Biogenesis was a high-priced mix of high-tech drugs.

According to documents the league obtained from Bioigenesis, the lab where Rodriguez and a slew of other baseball players went for their PEDs,  Rodriguez’s $12,000 per month drug regimen appears to utilize some of the most sophisticated drugs and diet programs in use today. In four distinct, month-long phases, Rodriquez’s cycle included hGH, GHRP, CJC, Testosterone cream, L-Glutathione cream, Melatonin, Testosterone Troche, Clomiphene, iGF-1, hCG and a host of other vitamins, omegas and other dietary supplements.

Tony Bosch, Biogenesis owner and the developer of this high-priced program, likely got most of the drugs for these programs from legitimate drug-makers through his father Pedro Bosch who is a family physician and was listed as Biogenesis’ medical director. However, some of the drugs in the list were likely procured through underground labs because investigational compounds like GHRP 2/6 are not available on any regulated market.

“My guess is that [Biogenesis] was getting them from [online sources] and administering and reselling it to [Rodriguez],” said Jose Garcia, MD, PhD, an endocrinologist at Baylor College of Medicine who has been involved in studies of GHRP 2/6 in an interview with MedPage Today. ”You would never go to a site like this because there is no quality control so you never know if these products are contaminated or if they contain what they’re supposed to. Not even for animal experiments.”

In exchange for immunity from lawsuits brought on by the MLB against Biogenesis and its associates, Tony Bosch turned over the evidence that eventually sunk Rodriguez.

Despite Dr. Garcia’s adamant plea for people to stop taking these kinds of drugs, they are known to the bodybuilding community as some of the best advances in lowering unwanted levels of estrogen during a testosterone cycle. But just as the hefty price tag for Biogenesis’ PED program indicates, these drugs can be very expensive.

As for Rodriguez, the most expensive part of his drug program will be his 162-game suspension from MLB which will take him out of the 2014 season completely – without pay.

As for Tony Bosch, now that Rodriguez has dropped all of his lawsuits against MLB, his players’ union and everyone else he threatened to sue over his getting caught, it looks like MLB will drop its own lawsuit against the Biogenesis founder on the grounds that he and his associates committed “intentional and unjustified tortious interference” with contracts between MLB and its players by providing them with banned substances.

It was MLB’s threat of litigation that forced Bosch to hand over information on Rodriguez and other baseball players who were using PEDs from Biogenesis, which is how the information on Rodriguez’ drug regimen (see below) was released.

Hexarelin

Hexarelin

L-Histidyl-2-methyl-D-tryptophyl-L-alanyl-L-tryptophyl-D-phenylalanyl-L-lysinamide; Examorelin

Molecular Formula C47H58N12O6
Molecular Weight 887.04
CAS Registry Number 140703-51-1

hexarelin12Hexarelin is a six-amino acid peptide.  Studies have shown that hexarelin is actually more effective and longer lasting than growth hormone releasing hormone (GHRH).  It is also known that GHRP-6 has a synergistic effect with GHRH, causing a far greater release than either of these substances alone.  By combining GHRP-6 with Hexarelin, a more potent GH releasing peptide combination is created than ever heard of. The potential clinical usefulness of these GH releasing hexapeptides is also reinforced by observations that long-term administration produces elevations in circulating IGF-1 concentrations.  Long term treatment with GHRP-6 similarly has been shown to elevate serum IGF-1 as well as IGF-binding protein-3 concentrations and promote linear growth.

MGF an alternatively spliced variant of IGF-1

MGF C-terminal peptide provided very significant protection to the vulnerable neurons.

 

The ischemic stroke is the third leading cause of death in developed countries. The C-terminal peptide of mechano-growth factor (MGF), an alternatively spliced variant of insulin-like growth factor 1 (IGF-1), was found to function independently from the rest of the molecule and showed a neuroprotective effect in vivo and in vitro. In vivo, in a gerbil model of transient brain ischemia, treatment with the synthetic MGF C-terminal peptide provided very significant protection to the vulnerable neurons. In the same model, ischemia evoked increased expression of endogenous MGF in the ischemia-resistant hippocampal neurons, suggesting that the endogenous MGF might have an important neuroprotective function. In an in vitro organotypic hippocampal culture model of neurodegeneration, the synthetic peptide was as potent as the full-length IGF-1 while its effect lasted significantly longer than that of recombinant IGF-1. While two peptides showed an additive effect, the neuroprotective action of the C-terminal MGF was independent from the IGF-1 receptor, indicating a new mode of action for this molecule. Although MGF is known for its regenerative capability in skeletal muscle, our findings demonstrate for the first time a neuroprotective role against ischemia for this specific IGF-1 isoform. Therefore, the C-terminal MGF peptide has a potential to be developed into a therapeutic modality for the prevention of neuronal damage. Dluzniewska J, et al.

Different roles of the IGF-I Ec peptide (MGF) and mature IGF-I in myoblast proliferation and differentiation

The physiological function of a recently cloned splice variant of insulin-like growth factor-I (IGF-I; mechano growth factor (MGF)) was studied using an in vitro cell model. Unlike mature IGF-I, the distinct E domain of MGF inhibits terminal differentiation whilst increasing myoblast proliferation. Blocking the IGF-I receptor with a specific antibody indicated that the function of MGF E domain is mediated via a different receptor. The results provide a basis for localized tissue adaptation and helps explain why loss of muscle mass occurs in the elderly and in dystrophic muscle in which MGF production is markedly affected.
