Once reconstituted AND kept in the refridgerator it WILL LAST FOR 30 DAYS. Some brands last for up to 60 days.
I don't care what the pharmacy guy told you. 30 days is the rule of thumb that I use.
There is nothing more effective than Human Chorionic Gonadotropin (HCG). The action of HCG is identical to that of pituitary LH. This takes place independently and is not affected by exogenous hormones and/or preexisting HPTA suppression. Therefore, it directly stimulates a dramatic increase in endogenous testosterone production, spermatogenesis and testicular volume. The primary goal during the first few weeks of PCT is to quickly restore testicular volume and function. Also, the dramatic increase in testosterone production is necessary to avoid and/or minimize the unfavorable "crash" effect. In the majority of individuals with larger testes at baseline, HCG alone is sufficient in restoring endogenous testosterone production as well at the induction of spermatogenesis which is most likely a result of residual FSH secretion. Once there is a plateau in the response to HCG, treatment with an FSH preparation such as human menopausal gonadotropin (HMG) or recombinant follicle stimulating hormone (rFSH) should be added in combination to HCG.
*The addition of an FSH preparation is rarely required and is best suited for severe cases of HH. FSH preparations are not readily available to most individuals. Therefore, there is no need to go into details with respect to its application at this time.
HCG is administered by subcutaneous (SC) or intramuscular (IM) injection. The average (3ml 22-25G x ⅝-1½”) syringe is adequate for IM injections but insulin syringes (½-1ml 28-30G x ½-1”) are recommended for SC injections. In regards to effectiveness, there should be no discernable difference between either of the techniques. The individual should opt for the most comfortable and/or convenient form of administration.
The following is a description of the available preparations by Serono:
HCG ampoules are supplied in 500, 1,000, 2,000, 5,000 and 10,000 IU preparations accompanied by 1 ml of sterile dilluent. It should be stored at a controlled room temperature (15-30 degrees C or 59-86 degrees F) and should be used immediately after reconstitution.
HCG multidose vials are supplied in 2,000, 5,000 and 10,000 IU preparations accompanied by 10 ml of bacteriostatic water. It should be stored at a controlled room temperature (15-30 degrees C or 59-86 degrees F), refrigerated (2-8 degrees C or 36-46 degrees F) after reconstitution and used within 30 days.
Other manufacturers are available and preparations may vary.
The terms international units (IUs) can occasionally cause confusion when reconstituting and measuring HCG. The actual process is quite elementary and the concentration per ml (cc) is dependant on the concentration of the lyophilized powder and the volume of dilluent used for reconstitution. For example, if you dilute 5,000 IUs HCG with 5ml (cc) solvent, the end result is 1,000 IUs per ml (cc). Divide the same 5,000 IUs with 10 ml (cc) and the end result is 500 IUs per ml (cc).
*Bacteriostatic water should always be utilized during reconstitution when long term (30 day) storage and multi dose administration are required.
