Some fat loss at 2-3iu daily, some additional, slight cosmetic muscular hardening, improved subjective wellbeing, skin, sleep, etc. if you’re in the 3-4iu daily. Some modest strength and joint fortification/injury risk reduction starts to really show up if you go into 4-6iu daily. For endurance, no benefits other than some body fat is now replaced with modest muscularity, which is why it’s not as easy to lose weight and lean out on hGH than it might appear. It will give no noteworthy advantages to your nitrogen retention or red blood cell compositions, which presumably increase the capacity to train for longer periods. If you have money for quality Genotropin or Norditropin then get that and do 1-3iu per day. The preconstituted liquid hGH is better preserved and less likely to be degraded or counterfeit brand; and if you cheap out get some chinese UGL hGH because at least it’s been around and those are big companies. Indian pharma and ugl is likely under dose or worthless from damage/defect. Russia has been experimenting with an easier recombinant process that uses DNA from a common lactobacilli strain instead of the more complicated and expensive e-coli DNA recombination pharma companies use as standard. First batch tested great but second production was like 85% hGH and had lots of fragments and potential contaminants. Most other peptide and smaller labs are gonna sell a 192 amino sequence but poorly bound terminal fragments and we suspect that increases antibodies to rhGH and reduces some effect. True 191 amino acid sequence rhGH is too tempting to cut corners or sell smaller sequence cutouts that do carry some benefit so feel legitimate, but no money or care went into production and there isn’t sufficient research on the differences Of small fragments versus 191 amino acid sequence that 50 years or research assures us the effects are bioidentical to endogenous hGH. lastly, Argument still exists about whether initial 191 sequence was better than its early pharma competitor that had a single addition and clocked in at 192 AA. They’re probably unclear scientifically because competitive research always makes major findings unnecessarily murky and less reliable- nobody’s kept up the comparison in medicine or translational sciences and so we’ll do well to stay safe with 191AA from a patented injection pen product (rhGH patents expired so Novo and Pfizer patented liquid preparations that came ready to inject in only their brand pen (you can use any insulin needle, really). But this does two thighs: 1) liquid formula is more resistant to time and temperature than anydrous powder you reconstitute at home; and 2) It made these liquid products modestly more controlled as patents kept stronger oversight for licensing to foreign companies and the extra step to accurately counterfeit both the box AND the pen (as well as to slink around the more uniform QR codes for patented non-generics) has made incentives to counterfeit humatrope from Lilly and similar generic pharma versions simply less of a hassle for counterfeiters.
In brief, black, grey, blue, or octomaroon colored tops matter zero unless that exact same production batch had lab analysis on equivalent unit samples. The color system was a good idea but dishonest dealers misappropriated it. Take .5 more dosage than I suggested above if you do get ugl. Either way, endurance probably won’t improve, but some AAS reduces endurance as composition changes or at least strains the body temporarily. Start at 0.006iu per kg of body weight; though adult prescriptions usually just say begin around 0.5iu for one to two weeks and keep increasing by the initial amount until month two starts at roughly 1.5iu/day, a moderate dose for medical purposes but you’ll continue to up this to 2 or 3 iu if qeno or nordo, and possibly up to 6-8iu if you’re in full PED and training to new limits training mode.
