Available Strengths
Unlike most compounds in our range, HGH is measured and dosed in International Units (IU) rather than milligrams, in line with standard conventions for growth hormone products. HGH is available wholesale in the following formats and strengths:
Vials
- HGH 10 IU (vial)
- HGH 15 IU (vial)
Pre-Filled Pens
- HGH 30 IU (pen)
- HGH 60 IU (pen)
All strengths and formats are available for bulk ordering with flexible MOQs. Private label and white-label packaging is available across both vials and pens — see our Private Label page for details.

Frequently Asked Questions
What is HGH?
HGH (Human Growth Hormone, also known as Somatropin) is a recombinant 191-amino-acid protein, identical in sequence to naturally occurring human growth hormone of pituitary origin. It is widely researched in performance, body composition, and endocrine science.
Why is HGH measured in IU rather than mg?
HGH is conventionally measured and dosed in International Units (IU), in line with standard pharmaceutical and research conventions for growth hormone products, rather than milligrams as used for most other peptides.
What purity does Peptide Direct's HGH meet?
All HGH supplied by Peptide Direct is verified by HPLC analysis to a minimum purity of ≥98% on a batch-by-batch basis, with a Certificate of Analysis supplied on every order.
What strengths and formats are available?
HGH is available wholesale as lyophilised vials (10 IU, 15 IU) and as ready-to-use pre-filled pens (30 IU, 60 IU), with flexible minimum order quantities for bulk buyers.
Can I get HGH under my own brand?
Yes. Private label and white-label packaging is available for qualifying wholesale buyers, across both vials and pre-filled pens. See our Private Label page for details.
How should HGH be stored?
Store refrigerated at 2–8°C, away from direct light. For long-term storage of vials, freezing conditions are recommended prior to reconstitution. Pre-filled pens should be kept refrigerated throughout storage and transit.
Is HGH manufactured under GMP conditions?
Yes. All HGH supplied by Peptide Direct is manufactured under GMP and ISO 9001:2015 certified conditions, the same standard applied across our full compound range.
