IGF-1 LR3 can be taken seven days a week in doses that range between 20-120mcg per day. Desensitization is common after 40 days or four weeks of use. Any muscle group in the body is suitable for injection of this peptide. Recommended time for administration of injection is during the morning or after weight training session. Half-life: 20 – 30 hours
It is noteworthy that high doses of IGF-1 have, on occasion, caused hypoglycaemia. Some have also indicated that IGF-1 was shown to increase tumour size in cancer patients although there is much debate on the veracity of this. It is believed that while this fact may be true for patients already suffering from cancer, IGF-1 is not a cause for cancer.
