What else the lab makes.
RU58841 Topical Solution
4.9 (88)·5/8% · 30/50/100 ml
Occupies the androgen receptor so DHT cannot deliver its signal to the follicle.
This is the cause, not the symptom. On its own it will not push a dormant follicle back into growth.
From €39,99

Pyrilutamide 0.5% (KX-826)
4.6 (16)·0.5% w/v · 30 mL
A newer topical androgen-receptor antagonist. Different molecule, same target as RU-58841.
For people who do not tolerate RU. Run one blocker or the other, not both.
€90,00

CB-03-01 2.5/5% (Clascoterone)
2.5/5% · 50 ml
Blocks the androgen receptor at the follicle, then breaks down in the skin into an inactive form.
The only one here that finished phase 3. Clascoterone sold much cheaper elsewhere is usually weaker than the label says.
From €89,00
Waitlist
Minoxidil 5%
4.6 (25)·5% · 60 mL
Extends the growth phase so follicles stay active longer. It does nothing to the hormone driving the loss.
Pairs with a blocker, never replaces one. Stop it and the growth it borrowed goes back.
€60,00

Ketoconazole Shampoo
An antifungal wash that handles the flaking and irritation sitting underneath a lot of shedding.
Two or three washes a week, alongside a blocker. It is not a blocker itself.

GHK-CU Copper Peptide Spray
4.5 (13)·Copper peptide · 30 mL
A copper peptide that works on the condition of the scalp itself. Not an antiandrogen; it does nothing to DHT.
For scalp quality. On its own it will not hold a receding hairline.
€50,00
Waitlist
Natural Hair Regrowth Serum
4.6 (13)·Topical · 50 mL
Caffeine, rosemary and botanical oils. Scalp support, and the mildest thing in the range.
A leg of the routine, not the whole table. It does not block DHT.
