The same full-length growth hormone, offered in a pack that skips the mixing step — or one that keeps it, if you would rather store it dry.
Ready-to-use liquid, or powder you reconstitute yourself.
Both forms are kept refrigerated at 2–8 °C, away from light.
Assessed across an extended window, like any growth-hormone work.
Marten is a branded recombinant human growth hormone: somatropin carrying the full 191–amino-acid sequence, the same active substance as our unbranded HGH 191AA. What sets it apart is presentation rather than chemistry — it is sold as a 100 IU pack in two forms, a pre-dissolved liquid and a conventional lyophilised powder.
The liquid pack is two 50 IU vials (16.5 mg each, 33 mg in total) in a buffered solution with stabilisers, so nothing is mixed before use. The powder pack is ten 10 IU vials, each reconstituted on its own like any other lyophilised vial. The manufacturer states a purity above 99%; the documentation supplied with the batch is available on request and we make no independent claim of our own.
Somatropin is an approved medicine for growth-hormone deficiency in clinical settings. Novapep supplies it strictly for research use.
How it works: Somatropin binds growth-hormone receptors and drives the liver to release IGF-1, the mediator behind most of its studied effects on tissue growth, recovery and fat metabolism. Liquid and powder deliver the same molecule; the difference is handling and stability, not pharmacology.
Researched to support: two formats, cold chain, long horizon.
Quality: Lyophilised (freeze-dried) powder, supplied for research use only. Our manufacturers carry out their own batch testing; we do not independently verify those results or issue certificates of analysis, so we back every order with our purity guarantee instead.
Find your protocol →Reconstitute: Use bacteriostatic water. Add it slowly down the inside wall of the vial and let it dissolve for 10 to 15 minutes. Do not shake.
Administer: Subcutaneous, usually with an insulin syringe.
Dose example: A 5 mg vial reconstituted with 1 ml gives 0.5 mg per 0.1 ml (10 units on a U-100 insulin syringe).
Store: Keep the powder cool and dry. Once reconstituted, store at 2 to 8 °C and use within about 28 days.

In research and clinical contexts somatropin is given subcutaneously, typically once daily:
Describes dosing used in clinical research, provided as reference only — not a usage recommendation or medical advice. This is an investigational research compound.
Clinical use: Recombinant somatropin is an approved treatment for growth-hormone deficiency and several other conditions, with decades of clinical data behind the molecule itself.
Liquid versus lyophilised: For somatropin generally, a stabilised liquid removes the reconstitution step and the handling error that comes with it, while a lyophilised powder is the more forgiving format for long storage before it is opened. Published comparisons address the format, not this brand.
Status: Supplied strictly as a research compound. Novapep has not independently tested this brand and does not present the manufacturer's figures as its own.
Provided as a scientific reference based on published clinical results — not medical advice, a usage recommendation, or a claim about the research product supplied by Novapep.
Digestive effects are the most common and usually ease with gradual titration. Scientific reference only, not usage instructions.
Delivery: FAN Courier, 24 to 48 hours across Romania. Dispatched within 1 to 2 business days.
Free shipping: On orders over 250 lei.
EU orders: Shipped from partner stock, typically within about 14 days.
Payment: Cash on delivery, card on delivery, or bank transfer.
Packaging: Discreet, kept cool after delivery.
Peptides are short chains of amino acids (2 to 50) that act as signalling molecules. Ours are supplied for laboratory research.
The vial contains lyophilised powder only. You also need bacteriostatic water, a sterile syringe, and a needle. We stock bacteriostatic water under Supplies.
Add bacteriostatic water slowly down the inside wall of the vial, then let it dissolve for 10 to 15 minutes. Do not shake.
Keep the powder cool and dry. After reconstitution, store at 2 to 8 °C and use within about 28 days.
Most are administered subcutaneously with an insulin syringe, for slow, steady absorption. A few formulations use other routes.
It varies by peptide and protocol. Some are researched over a few days, others over several weeks.
A prescription is not required, but we recommend speaking with your doctor, especially if you have a medical condition or take other medication.
Our manufacturers carry out their own batch testing, but we do not test independently and do not hold certificates of analysis — so we make no purity claim of our own. We back it with a guarantee instead: you are welcome to have a vial independently tested — contact us first so we agree the laboratory. If the result doesn’t match the label, we reimburse the cost of the test and either replace the product or refund it.
