QUESTIONABLE INFO ON HALF LIFE ONCE INJECTED?
None of the information on this here is guaranteed to be accurate. Use at your own risk.
The formula used for calculating the rate of compound release at a given day t is: λ * N(t) Where λ is the decay constant equal to ln(2)/h, h being the half life of the compound given in days; and N(t) is the half-life equation given by: N(t) = n * e^(-t/λ) Where n is the original dose of the compound in mg and t is given in days. Terminal Half-lives Testosterone Propionate: 0.8 days Testosterone Phenylpropionate: 1.5 days Testosterone Isocaproate: 4.0 days Testosterone Enanthate: 4.5 days Testosterone Cypionate: 5.0 days Testosterone Decanoate: 7.5 days Testosterone Undecanoate: 20.9 days Trenbolone Acetate: 1.0 days Trenbolone Enanthate: 4.5 days Masteron Propionate: 0.8 days Masteron Enanthate: 4.5 days Nandrolone Phenylpropionate: 1.5 days Nandrolone Decanoate: 7.5 days Equipoise: 14.0 days Primobolan Oral: 5 hours Primobolan Injectable: 4.5 days Halotestin: 7 hours Anadrol: 14 hours Dianabol: 5 hours Turinabol: 16 hours Winstrol Oral: 8 hours Winstrol Injectable: 1.0 days Anavar: 10 hours Superdrol: 10 hours These half-lives are approximations, and may vary slightly depending on injection site, carrier oil, and other factors. Note: A different list of half-lives is often copy and pasted on various sites, claiming that, for example, the half-life for the propionate ester is 4.5 days and that the half-life for the enanthate ester is 10.5 days. This list is incorrect, and is the result of flawed calculations many years ago. See the "References" section for more information. Active Dose Injectable steroids are typically bound by esters, which comprise a portion of the steroid's weight. Because of this, 100mg of, for example, testosterone enanthate does not equate to 100mg of pure testosterone. In this case, there is only 70mg of testosterone being injected, and the remaining 30mg is the enanthate ester. This is taken into account when plotting cycles on this site, as different esters have different weights. Listed below is the percentages of the actual hormones for different steroid and ester combinations: Testosterone Propionate: 80% Testosterone Phenylpropionate: 66% Testosterone Isocaproate: 72% Testosterone Enanthate: 70% Testosterone Cypionate: 69% Testosterone Decanoate: 62% Testosterone Undecanoate: 61% Trenbolone Acetate: 87% Trenbolone Enanthate: 70% Masteron Propionate: 80% Masteron Enanthate: 70% Nandrolone Phenylpropionate: 67% Nandrolone Decanoate: 64% Equipoise: 61% Primobolan Oral: 100% Primobolan Injectable: 70% Halotestin: 100% Anadrol: 100% Dianabol: 100% Turinabol: 100% Winstrol Oral: 100% Winstrol Injectable: 87% Anavar: 100% Superdrol: 100% References Behre HM, Nieschlag E. 1998 Comparative pharmacokinetics of testosterone esters.

I'm just trying to fit in thanks Big Bro . New to boards trying to make right moves and speak truth from my mistakes. I know how important it is to do stuff right. We learn from trials and errors. If I can cut some of the brothers errors they can achieve their goal and pass onto another brother to reach his or her goal. Thank you for acknowledgment Dakota. 14 years in the game and hoping to make it to the big Dance one day. I'm free to speak out if I ever make it to top 10 of NPC I'd be limited to what you can openly speak about or risk being black balled from winning another show. This is the Route Rich Piana chose. I didn't agree with everything he said and did, but he always Knew I respected him being truthful as to what (he did). I just felt to many young bloods were watching. There is a time and place for everything. I had his back at a few expose. it was never personal. I just felt (parental discretion) over 20's and do open talks at seminars. He had the fan base. But who am I to tell that man what to do. I did but he had his own dream and I respects a man's dream as long as he is not putting out bad information to guys in the game. The moment Rich pissed the supplement companies off by speaking truth I knew he had to have a plan. In short I got the idea from Rich speak truth. I speak to the safety of what one injects in their body. You don't want your body attacking it's self it will screw up your immune system. A bad case is similar sides as HIV. Keep it clean and keep it real. Don't be to lazy to wipe the area down twice before entering.
