It's really sad. First off I see guys spending thousands and thousands of $ on AAS, and HCG but when it comes to PCT they can only afford a OTC or 20MG of Nolvadex for 4 weeks. My question is how important is blood work to you and how often do you get it.?
A/G Ratio - Albumin - Alkaline Phosphatase - Bilirubin, Total - Cholesterol - GGT Globulin - LDH - Protein, Total - AST/SGOT - ALT / SGPT Liver Enzymes ALT OR SGPT ALT, an enzyme appears in liver cells, with lesser amounts in the kidneys, heart, and skeletal muscles, and is a relatively specific indicator of acute liver cell damage. When such damage occurs, ALT is released from the liver cells into the bloodstream, often before jaundice appears, resulting in abnormally high serum levels that may not return to normal for days or weeks. The purpose of this blood serum test is to help detect and evaluate treatment of acute hepatic disease, especially hepatitis, and cirrhosis without jaundice. To help distinguish between mytyocardial (heart) and liver tissue damage (used with the AST enzyme test). Also to assess hepatotoxicity of some drugs. ALT levels by a commonly used method range from 10 to 32 U/L; in women, from 9 to 24 U/L. (There does exist differing ranges used by various laboratories.) The normal range for infants is twice that of adults. Very high ALT levels (up to 50 times normal) suggest viral or severe drug- induced hepatitis, or other hepatic disease with extensive necrosis (death of liver cells). (AST levels are also elevated but usually to a lesser degree.) Moderate-to-high levels may indicate infectious mononucleosis, chronic hepatitis, intrahepatic cholestasis or cholecystitis, early or improving acute viral hepatitis, or severe hepatic congestion due to heart failure. Slight-to-moderate elevations of ALT (usually with higher increases in AST levels) may appear in any condition that produces acute hepatocellular (liver cell) injury, such as active cirrhosis, and drug-induced or alcoholic hepatitis. Marginal elevations occasionally occur in acute myocardial infarction (heart attack), reflecting secondary hepatic congestion or the release of small amounts of ALT from heart tissue. Many medications produce hepatic injury by competitively interfering with cellular metabolism. Falsely elevated ALT levels can follow use of barbiturates, narcotics, methotrexate, chlorpromazine salicylates (aspirin), and other drugs that affect the liver. Be Aware: Serum liver enzymes can create confusion for both patients and physicians for these tests are highly sensitive, but very non-specific. Tests commonly referred to as liver function tests or LFT's do not actually determine liver function. Instead, they are static, primarily diagnostic parameters that serve to detect liver disease rather than quantitative liver function. Rather than liver function tests, it is more useful to refer to these tests as serum liver tests and to mentally categorise them according to the pathophysiologic processes they truly reflect.
SGPT (Serum Glutamic-Pyruvic Transaminase - ALT)
Serum Glutamic Pyruvic Transaminase or ALT is an enzyme found primarily in the liver but also to a lesser degree, the heart and other tissues. It is useful in diagnosing liver function more so than SGOT levels. Decreased SGPT in combination with increased cholesterol levels is seen in cases of a congested liver. We also see increased levels in mononucleosis, alcoholism, liver damage, kidney infection, chemical pollutants or myocardial infarction. Normal Adult Range: 0 - 48 U/L
Optimal Adult Reading: 24
AST or SGOT One of the two main liver function blood serum tests (the other being the ALT test). The purpose of this blood test is to detect a recent myocardial infarction (heart attack); to aid detection and differential diagnosis of acute hepatic disease and to monitor patient progress and prognosis in cardiac and hepatic diseases. AST levels by a commonly used method range from 8 to 20 U/L although some ranges may express a maximum high in the 40s. (Check with your physician.) AST levels fluctuate in response to the extent of cellular necrosis (cell death) and therefore may be temporarily and minimally elevated early in the disease process, and extremely elevated during the most acute phase. Depending on when the initial sample was drawn, AST levels can rise- indicating increasing disease severity and tissue damage- or fall- indicating disease resolution and tissue repair. Thus, the relative change in AST values serves as a reliable monitoring mechanism. Maximum elevations are associated with certain diseases and conditions. For example, very high elevations (more than 20 times normal) may indicate acute viral hepatitis, severe skeletal muscle trauma, extensive surgery, drug- induced hepatic injury, and severe liver congestion. High levels (ranging from 10 to 20 times normal) may indicate severe myocardial infarction (heart attack), severe infectious mononucleosis, and alcoholic cirrhosis. High levels may also occur during the resolving stages of conditions that cause maximal elevations. Moderate-to-high levels (ranging from 5 to 10 times normal) may indicate chronic hepatitis and other conditions. Low-to-moderate levels (ranging from 2 to 5 times normal) may indicate metastatic hepatic tumours, acute pancreatitis, pulmonary emboli, alcohol withdrawal syndrome, and fatty liver (steatosis).
Serum Glutamic Oxalocetic Transaminase or AST is an enzyme found primarily in the liver, heart, kidney, pancreas, and muscles. Seen in tissue damage, especially heart and liver, this enzyme is normally elevated. Vitamin B deficiency and pregnancy are two instances where the enzyme may be decreased.

MCH (Mean Corpuscular Hemoglobin)
Hemoglobin x 10
R.B.C. Mean Corpuscular Hemoglobin (MCH) gives the average weight of hemoglobin in the red blood cell. Due to its use of red blood cells in its calculation, MCH is not as accurate as MCHC in its diagnosis of severe anaemia’s. Decreased MCH is associated with microcytic anemia and increased MCH is associated with macrocytic anaemia. Normal Adult Range: 27 - 33 pg

MCHC (Mean Corpuscular Hemoglobin Concentration)
Hemoglobin x 100 Hematocrit This test measures the average concentration of hemoglobin in red blood cells. It is most valuable in evaluating therapy for anaemia because Hemoglobin and Hematocrit are used, not R.B.C. in the calculation. Low MCHC means that a unit of packed R.B.C.’s contain less hemoglobin than normal and a high MCHC means that there is more hemoglobin in a unit of R.B.C.’s. Increased MCHC is seen in spherocytosis, and not seen in pernicious anaemia whereas decreased levels may indicate iron deficiency, blood loss, B6 deficiency of thalassemia.

Common Laboratory Tests in Liver Diseases Howard J. Worman, M. D. ALT - AST - Alkaline phosphatase - Gamma-glutamyltranspeptidase (GGT) - Bilirubin - Albumin - Prothrombin time (PT) - Platelet count - Serum protein electrophoresis The diagnosis of liver diseases depends upon a combination of history, physical examination, laboratory testing and sometimes radiological studies and biopsy. Only a physician who knows all of these aspects of a specific case can reliably make a diagnosis. Many individuals with liver diseases nonetheless have questions about their laboratory test results and seek information about their significance. The purpose of this page is to briefly describe some of the common laboratory tests that may be abnormal in individuals with liver diseases. Patients reading this page must keep in mind that abnormalities of these laboratory tests are not diagnostic of specific diseases and that only a qualified physician who knows the entire case can provide a reliable diagnosis. Alanine aminotransferase (ALT) ALT is an enzyme produced in hepatocytes, the major cell type in the liver. ALT is often inaccurately referred to as a liver function test, however, its level in the blood tells little about the function of the liver. The level of ALT in the blood (actually enzyme activity is measured in the clinical laboratory) is increased in conditions in which hepatocytes are damaged or die. As cells are damaged, ALT leaks out into the bloodstream. All types of hepatitis (viral, alcoholic, drug-induced, etc.) cause hepatocyte damage that can lead to elevations in the serum ALT activity. The ALT level is also increased in cases of liver cell death resulting from other causes, such as shock or drug toxicity. The level of ALT may correlate roughly with the degree of cell death or inflammation, however, this is not always the case. An accurate estimate of inflammatory activity or the amount cell death can only be made by liver biopsy. (See also aspartate aminotransferase below.) Aspartate aminotransferase (AST) AST is an enzyme similar to ALT (see above) but less specific for liver disease as it is also produced in muscle and can be elevated in other conditions (for example, early in the course of a heart attack). AST is also inaccurately referred to as a liver function test by many physicians. In many cases of liver inflammation, the ALT and AST activities are elevated roughly in a 1:1 ratio. In some conditions, such as alcoholic hepatitis or shock liver, the elevation in the serum AST level may higher than the elevation in the serum ALT level. Alkaline phosphatase Alkaline phosphatase is an enzyme, or more precisely a family of related enzymes, produced in the bile ducts, intestine, kidney, placenta and bone. An elevation in the level of serum alkaline phosphatase (actually enzyme activity is measured in the clinical laboratory), especially in the setting of normal or only modestly elevated ALT and AST activities, suggests disease of the bile ducts. Serum alkaline phosphatase activity can be markedly elevated in bile duct obstruction or in bile duct diseases such as primary biliary cirrhosis or primary sclerosing cholangitis. Alkaline phosphatase is also produced in bone and blood activity can also be increased in some bone disorders. Gamma-glutamyltranspeptidase (GGT) An enzyme produced in the bile ducts that, like alkaline phosphatase, may be elevated in the serum of patients with bile duct diseases. Elevations in serum GGT, especially along with elevations in alkaline phosphatase, suggest bile duct disease. Measurement of GGT is an extremely sensitive test, however, and it may be elevated in virtually any liver disease and even sometimes in normal individuals. GGT is also induced by many drugs, including alcohol, and its serum activity may be increased in heavy drinkers even in the absence of liver damage or inflammation. Bilirubin Bilirubin is the major breakdown product that results from the destruction of old red blood cells (as well as some other sources). It is removed from the blood by the liver, chemically modified by a process call conjugation, secreted into the bile, passed into the intestine and to some extent reabsorbed from the intestine. Bilirubin concentrations are elevated in the blood either by increased production, decreased uptake by the liver, decreased conjugation, decreased secretion from the liver or blockage of the bile ducts. In cases of increased production, decreased liver uptake or decreased conjugation, the unconjugated or so-called indirect bilirubin will be primarily elevated. In cases of decreased secretion from the liver or bile duct obstruction, the conjugated or so-called direct bilirubin will be primarily elevated. Many different liver diseases, as well as conditions other than liver diseases (e. g. increased production by enhanced red blood cell destruction), can cause the serum bilirubin concentration to be elevated. Most adult acquired liver diseases cause impairment in bilirubin secretion from liver cells that cause the direct bilirubin to be elevated in the blood. In chronic, acquired liver diseases, the serum bilirubin concentration is usually normal until a significant amount of liver damage has occurred and cirrhosis is present. In acute liver disease, the bilirubin is usually increased relative to the severity of the acute process. In bile duct obstruction, or diseases of the bile ducts such as primary biliary cirrhosis or sclerosing cholangitis, the alkaline phosphatase and GGT activities are often elevated along with the direct bilirubin concentration. Albumin Albumin is the major protein that circulates in the bloodstream. Albumin is synthesized by the liver and secreted into the blood. Low serum albumin concentrations indicate poor liver function. The serum albumin concentration is usually normal in chronic liver diseases until cirrhosis and significant liver damage is present. Albumin levels can be low in conditions other than liver diseases including malnutrition, some kidney diseases and other rarer conditions. Prothrombin time (PT) Many factors necessary for blood clotting are made in the liver. When liver function is severely abnormal, their synthesis and secretion into the blood is decreased. The prothrombin time is a type of blood clotting test performed in the laboratory and it is prolonged when the blood concentrations of some of the clotting factors made by the liver are low. In chronic liver diseases, the prothrombin time is usually not elevated until cirrhosis is present and the liver damage is fairly significant. In acute liver diseases, the prothrombin time can be prolonged with severe liver damage and return to normal as the patient recovers. Prothrombin time can also be prolonged in cases of vitamin K deficiency, by drugs (warfarin, used therapeutically as an anti-coagulant, prolongs the prothrombin time) and in non-liver disorders. Platelet count Platelets are the smallest of the blood cells (actually fragments of larger cells known as megakaryocytes) that are involved in clotting. In some individuals with liver disease, the spleen becomes enlarged as blood flow through the liver is impeded. This can lead to platelets being sequestered in the enlarged spleen. In chronic liver diseases, the platelet count usually falls only after cirrhosis has developed. The platelet count can be abnormal in many conditions other than liver diseases. Serum protein electrophoresis In this test, the major proteins in the serum are separated in an electric field and their concentrations determined. The four major types of serum proteins whose concentrations are measured in this test are albumin, alpha-globulins, beta-globulins and gamma-globulins. Serum protein electrophoresis is a useful test in patients with liver diseases as it can provide clues to several diagnostic possibilities. In cirrhosis, the albumin may be decreased (see above) and the gamma-globulin elevated. Gamma-globulin can be significantly elevated in some types of autoimmune hepatitis. The alpha-globulins can be low in alpha-1-antitrypsin deficiency.

You need at least a lipid profile/hormone panel done. You can go to your local hospitial and have the blood work done. I am not 100% sure where you can get your blood tested online. Did you try a google search bro?
