Keifei???

Hi chaps.

Anyone got any feedback on Keifei gear? I've searched through a few pages under this forum and haven't come across anything yet.

Cheers.

You're not looking hard enough

There are a few other posts on Keifei HGH. Just go through the HGH-IGF-Insulin threads

I personally would stick with Biotech Kefei rather than Keifei.

Still think a lab that claims to make a 200mg proprionate ester shouldn't be trusted as that is physically impossible to make.

Thanks StuartF. Maybe i should elaborate as most people tend to refer directly to HGH when Keifei is mentioned. Keifei have a range of anabolic injectables and tabs besides the HGH - Keifeibioresearch.

Is there perhaps any info/feedback on this?

i was talking about the keifei juice,they claim to make a 200mg prop,that is impossible,i know stuart has used the stuff lets see what his feed back on it is...

haha, ya, it was 200mg/ml Masteron prop made my Keifei. I paid a bloody fortune for the stuff and the results were no better than PGW Masteron Prop (100mg/ml) at the same dosage.

Like DJ said, it is impossible to fit 200mg Masteron Prop ester into 1ml of oil. Any UG lab that claim to beat science can't be trusted IMO.

Thanks for the "heads up".

I'm not too clued up on the science of juice with regard to esters as DJ has pointed out with the 200mg prop. The only thing i'm familiar with are the diferent types and their function which is the timed release of testosterone. I dont understand the compound structure and therefore am lost when you say it is impossible to fit 200mg Masteron Prop ester into 1ml of oil.

Any possiblity in breaking this down for me?

An analogy would be adding suger to water. Once you have reached saturation, no more suger will dissolve in the water. Same goes for esters, a 100mg propionate ester will saturate in 1ml of oil.

While we're on the subject, can i confirm that in test when you take the molecular weight of the base minus the molecular weight of the esters leaves you with free test, and this free test is ultimately what the body consumes at the rate of which the esters allow for consumption?

Trying to latch on to the physics side of things here.

Sounds about right to me

Don't know if I quite agree with that. It's not the free test that the body uses but the testosterone molecule that is bonded to the ester group. The reason for adding an ester is to improve the solubility of test in oil, and depending on the type of ester will determine the rate at which test is absorbed into the body.

Thanks. And the free test....what role does it play?



The reason i understood it to be as i've asked above is because of the following:

I moved your post to the correct category.

I'm not going to answer your question and will leave that to the site members. One thing I want to point out though without tying to steer the thread off topic is that the number of esters is not making a substance more powerful. In fact the opposite is the case... I'm going to quote my old post:

Let me explain... you see there are 7 esters attached to varying amounts of active testosterone molecules, 4 of which are very long and heavy esters.

Isocaproate 20mg/ml - 7%
Phenylpropionate 20mg/ml - 7%
Propionate 20mg/ml - 7%
Cypionate 40mg/ml - 13%
Enanthate 40mg/ml - 13%
Decanoate 90mg/ml - 30%
Undecylenate 70mg/ml - 23%

What that means is that in that 300mg mix a massive amount of that weight will be due to the big/heavy esters... eg. Decanoate and Undecylenate.

(File Removed)

Let’s look at what part the esters play in the final weight per dosage.

Please note I'm working with percentages below and not actual g/mol

Testosterone: Molecular Weight: 288 * 100 = 28800 (This is the ideal for pure testosterone)

Isocaproate: Molecular Weight: 98 * 7 = 686
Phenylpropionate: Molecular Weight: 132 * 7 = 924
Propionate: Molecular Weight: 56 * 7 = 392
Cypionate: Molecular Weight: 124 * 13 = 1612
Enanthate: Molecular Weight: 112 * 13 = 1456
Decanoate: Molecular Weight: 154 * 30 = 4620
Undecylenate: Molecular Weight: 166 * 23 = 3818

Total ester weight = 13508

Amount of free testosterone = 28800 – 13508 = 15292

Percentage of actual testosterone = 53%
Percentage of esters = 47%

I'm not 100% sure that my calculations are correct... I will get my chemistry books later if we want to go into more detail. If I'm correct it shows that you will only get 53% free testosterone in that mix the rest are useless esters, that only make up weight.

Another thing: Why the hell do you want Cypionate and Enanthate in the same mix... there's only a single carbon atom difference... probably for marketing purposes... 7 testosterones looks pretty good on paper...

Emphasis on: "I'm not 100% sure that my calculations are correct... I will get my chemistry books later if we want to go into more detail. If I'm correct it shows that you will only get 53% free testosterone in that mix the rest are useless esters, that only make up weight."

As I understand it, the "free test" is the testosterone that is left behind once the esters have been broken down by the body's enzymes.

What does your body do with the "free test"?

Makes your muscles Beeeeeg

Hahaha...ok.

Managed to find the following and i understand now:
"Slowing the release of the parent steroid is a great benefit in steroid medicine, as free testosterone (or other steroid hormones) previously would remain active in the body for a very short period of time (typically hours). Esterification temporarily deactivates the steroid molecule. With a chain blocking the 17th beta position, binding to the androgen receptor is not possible (it can exert no activity in the body). In order for the compound to become active the ester must therefore first be removed. This automatically occurs once the compound has filtered into blood circulation, where esterase enzymes quickly cleave off (hydrolyze) the ester chain. This will restore the necessary hydroxyl (OH) group at the 17th beta position, enabling the drug to attach to the appropriate receptor. Now and only now will the steroid be able to have an effect on skeletal muscle tissue."
