SARMs can be taken orally as well, and regularly stacked together for improved results. They have been around for years now (although only recently gaining popularity) and there is a wealth of studies done on them as well. Check out our blog for a run-down of the most comprehensive and recent studies and how SARMs has been demonstrated to show positive changes.
But IGF-1 injections may soon be a thing of the past. Future use of IGF-1 will no doubt involve gene therapy, which directly targets genes that produce IGF-1 in muscle, usually by attaching specific gene activators to an inactive virus or vector that then enters into muscle cells. Studies in mice show that a procedure like this can cause a 15% increase in muscle mass, along with a 14% increase in strength. Gene therapy in old mice has been shown to cause to a 27% increase in strength, along with regeneration of aging muscle. In one mouse study, the IGF-1 gene was placed in the animals’ glutes and calves, which resulted in up to a 115% increase in muscle-cross-sectional area.
Cerebrolysin—also known as FPE 1070—is a synthetic nootropic drug. Nootropic drugs are substances that enhance cognitive functions such as memory, creativity, and motivation in otherwise healthy individuals. This peptide is extremely small, allowing it to penetrate the blood-brain barrier and act directly on the neurons of the central nervous system. Cerebrolysin has been found to improve the metabolic activity of brain tissue, shield neurons from harmful substances, and stimulate the peripheral and central nervous systems. In addition to its utility as a nootropic substance, the drug has potential as part of a treatment plan addressing Alzheimer’s disease, stroke, and moderate to severe head injury.
Phenylephrine is a direct alpha-1 adrenergic agonist, with weak alpha-2 adrenergic agonist activity. It also has very weak beta-adrenergic effects, but at therapeutic doses there are no significant stimulating beta-1 adrenergic effects on the heart, or on the bronchial airways, or on peripheral blood vessels. This contrasts with pseudoephedrine, which has greater beta-adrenergic activity. The effect on the alpha-adrenergic receptors leads to local vasoconstriction and shrinking of mucous membranes. There is no anti-histamine effect. The drug is readily and completely absorbed following oral administration, undergoing extensive first pass metabolism in the intestinal wall and in the liver leading to some variability in individual pharmacokinetics. Nasal decongestion is apparent within 15 to 20 minutes and persists for up to 4 hours (AHFS 2007).
In extracardiac models of striated muscles atrophy, GHRP-2 exerted a potent myoprotective effect, presumably via the direct agonistic stimulation of the GHS-R1a since no elevation of IGF-1 transcript was observed.49 Thus, it is likely that GHRP cardioprotective effects in scenarios of DCM may be somehow mediated by a trophic or anabolic mechanism. Based on the benefits of GHRP-6 on muscle functions, a newly synthesized GHRP-6-biotin conjugate tested on cultured myoblasts showed that it induced the expression of myogenic proteins and IGF-1 levels similar to the concentrations of energy metabolites and the corresponding enzymes. Practical applications of the GHRP-6-biotin conjugate could include amelioration of sarcopenia and/or cardiac cachexia.50
Regular GH used to be manufactured from cadavers, a grim prospect indeed, but it’s latterly become synthesised in a lab, making it a little safer because the human derived version risked causing Creutzfeldt-Jakob disease – a degenerative neurological disorder that almost always proved tombstone-worthy. The first synthetic version was a direct substitute for the GH that your body manufactures, so over-zealous muscle-hungry punters risked overloading their body with too much, leading to the tell-tale side effects like a Desperate Dan jaw, nerve pain and even increased tumour growths. This is where GHRP6 earns its keep because it tells your pituitary gland to begin secreting more natural GH. You get a solid pulse in your own natural GH levels, as well as an increase in insulin growth like factor 1 (IGF-1) secreted by your liver. IGF-1 helps your body metabolise more protein so your entire body becomes more anabolic from its own supplies, not synthetic versions.
