How to choose the best HGH brand?
When visiting our website, people are often confused by our selection of 10 different HGH brands: which one to choose, why some are more expensive than the others, what’s the difference between powder and premixed HGH, pens vs vials, and so on.
First of all, you need to understand that there is no significant difference between HGH brands. You may consider them as generic versions of the same drug just as with Ibuprofen – there are dozens of brands – Motril, Advil, Nurofen, etc — that all contain Ibuprofen and provide the same benefits. It’s similar to HGH.
HGH is measured in IU (international units) and mg (milligrams). 10 IU is 3.33 mg.
1 mg = 3 units of HGH.

Vials vs Injector Pens, Premixed vs Powder Form
HGH comes in powder and premixed forms. The powder is usually packaged in 10-14 IU vacuum-sealed vials. You need to dissolve the powder with bacteriostatic or sterile water and then inject the solution with an insulin syringe.
Powder HGH is considered to be a standard form. To keep it stable manufacturers add preservatives such as mannitol and glycine to the vials.

HGH injector pens/cartridges HGH are commonly used for pharma-grade HGH brands: Genotropin, Norditropin, Humatrope, Saizen, Omnitrope

Saizen and Omnitrope are not pens, but they are cartridges for the pens. The pens are hard to find, so usually, cartridges are used with a simple insulin syringe just like for powder HGH. Norditropin and Genotropin
come in injector pens. They allow you to set up the dosage and the injections are seamless compared to insulin syringes.
Temperature and HGH
Synthetic human growth hormone is a thermolabile product. This means that it should be stored in a fridge to retain its properties. However, there is confusion here. Some people think that HGH is very fragile and that even the smallest exposure to heat will instantly make it useless. Good news, that’s not the case.
In fact, HGH degradation is a long and gradual process. In the first weeks, there might be no change to its integrity at all. After 2-3 weeks some of the proteins might get damaged, and the peptide bonds between amino acids disrupted, leading to a decrease in purity.
But again it’s not a drastic change.
And there is no point in time
when HGH disintegrates.
It’s important to note that powder
HGH is considered to be more
stable against heat than premixed
HGH.
However, it all depends on
the preservatives used by the
manufacturer. The preservatives
used by pharma-grade

manufacturers and reputable generics manufacturers allow HGH to keep its structure in the heat for weeks and months with no significant change. However, when the temperature climbs, we advise to either order powder
HGH with standard delivery (up to 2 weeks) or premixed HGH, but with express delivery (UPS and Fedex offer 3-5 days delivery) to avoid any damage in transit due to hot weather.
Pharma Grade vs Non-Pharma Grade
Brands
An important distinction you need to understand is pharma-grade vs non-pharma-grade brands.
Pharma-grade brands are made by big pharma companies (Genotropin by Pfizer, Norditropin by Novo Nordisk, Humatrope by Elli Lilli, Saizen by Merck, Omnitrope by Sandoz) and then distributed through the pharmacies around the world. You can be 100% sure of the quality control of the facilities and their products’ high purity level.
Due to high manufacturing, research, and development
costs, as well as pharmacy markups, pharma-grade brands tend to be more expensive. For instance, in our store, 1 IU of Norditropin is about $4, while 1 IU of a generic brand, like Spectros’ Zptropin, is $2
Manufacturers of generic HGH (Spectros, Zptropin, Hygetropin, Hutrope etc) sell drugs in a different way. For production, they usually use the same equipment as bigger pharmaceutical companies or even manufacture
their products at the same facility. But they cut the costs of distribution through pharmacies, not to mention their marketing costs, and work directly with big online distributors and store owners.
The absence of pharmacy retail is not a sign of low quality but rather a conscious choice for these manufacturers. Generic HGH is produced at the GMP-certified facilities and follows quality control standards just like big pharma companies’ HGH.
In addition to that, most generic HGH brands on the market have an anti-counterfeit system built into the product package to protect them from fakes
The current level of technology allows small manufacturers to achieve the same level of purity as big manufacturers have.
HGH Purity
When we talk about HGH quality, we mean purity. Basically, it means the level of similarity between the exogenous growth hormone and endogenous growth hormone.
The higher purity is, the better the exogenous growth hormone works in the body. Your organism doesn’t react to it as an external hormone. Low HGH purity may lead to immune reactions in the form of side effects –
the organism doesn’t recognize the external substance and attacks it instead of absorbing it and getting all the benefits.
It’s vital to note that pharmaceutical growth hormone is required to be at a purity level higher than 92%. What’s interesting is that generic HGH manufacturers are more concerned about achieving purity than pharmaceutical giants. Lab tests performed by an independent lab
showed that generic Zptropin was 99.93 % pure, while pharma-grade Omnitrope in comparison was just 96 %.
So, which HGH to choose?
The bottom-line: if money isn’t a deal-breaker for you, definitely go with pharma-grade brands. Our bestsellers are Nordtiropin and Genotropin, so choose one of them and you will be satisfied.
Otherwise, go for generic brands like Zptropin or Spectros – well-known and reputable brands you can get for half the price per 1 IU of pharma-grade HGH. And in some cases, you can even expect them to be purer than pharma-grade brands.
