Injectable steroids are injected into muscle tissue, not into the veins. They are slowly released from the muscles into the rest of the body, and may be detectable for months after last use. Injectable steroids can be oil-based or water-based. Injectable anabolic steroids which are oil-based have longer half-life than water-based steroids. Both steroid types have much longer half-lives than oral anabolic steroids. And this is proving to be a drawback for injectables as they have high probability of being detected in drug screening since their clearance times tend to be longer than orals. Athletes resolve this problem by using injectable testosterone early in the cycle then switch to orals when approaching the end of the cycle and drug testing is imminent.
Valproic acid was first synthesized in 1882 by Beverly S. Burton as an analogue of valeric acid , found naturally in valerian .  Valproic acid is a carboxylic acid , a clear liquid at room temperature. For many decades, its only use was in laboratories as a "metabolically inert" solvent for organic compounds. In 1962, the French researcher Pierre Eymard serendipitously discovered the anticonvulsant properties of valproic acid while using it as a vehicle for a number of other compounds that were being screened for antiseizure activity. He found it prevented pentylenetetrazol -induced convulsions in laboratory rats .  It was approved as an antiepileptic drug in 1967 in France and has become the most widely prescribed antiepileptic drug worldwide.  Valproic acid has also been used for migraine prophylaxis and bipolar disorder. 
Started with 2 iu and bumped to 4. Started noticing carpel tunnel syndrome and achy joints for the first few weeks. Later adjusted the dose to 3 ius. Loving this hgh and no doubt this is one of the best and perfectly dosed pharmaceutical grade product. With generics never felt that way especially at a 3 iu dose. Cartridges are easy to use. No lumps, redness or swelling at the injection site.
My wife has noticed that my skin is looking better. My energy levels were far worse prior to its use. Life and training has never been so great. Loosing fat quickly around the belly region. Enjoying cardio and training sessions. Sleeping has never been so easy as well. I just lay on bed and close my eyes and within few minutes deep asleep.
I'm running a combo of T3 and T4 alongside and don't feel any lethargy during the day.
