How to choose
You do not have to choose alone. In the online visit you share your goals and health history, and a licensed provider decides which program, if either, is appropriate. Questions to bring: what you hope to support (skin, recovery or both), any history of cancer, any copper allergy, and every medication you take.
Who should skip both
- Pregnant, breastfeeding or trying to conceive
- Active cancer or a history of cancer
- Under 18
- Competing in a sport that tests under WADA rules
- Copper allergy or Wilson's disease
Awesentials provides no medical services. Peptides in this program are compounded by a licensed US pharmacy for an individual patient. They are not FDA-approved, most research on them comes from lab and animal studies, and evidence in people is limited. No result is promised. BPC-157, TB-500 (thymosin beta-4 fragments) and MOTS-c are on the World Anti-Doping Agency (WADA) Prohibited List. If you compete in a tested sport, check your sport's anti-doping rules and talk to your provider before starting. A licensed provider decides whether any program is appropriate for you.
