Allergic Reaction?
36M test subject had a pretty concerning reaction after peptide administration and figured it was worth sharing in case anyone else has experienced something similar.
Initial protocol included:
- BPC 157
- TB 500
- Ipamorelin
- Tesamorelin
Shortly after administration, subject developed:
- diffuse hives
- intense flushing (“red as a lobster”)
- tachycardia with HR over 140 bpm
Reaction escalated enough that he went to the ER due to concern for anaphylaxis or severe allergic response. In the ER he was treated with epinephrine and antihistamines, after which symptoms stabilized. No airway compromise occurred.
At first, BPC 157 was suspected as the culprit. However, after additional isolated testing, BPC now appears unlikely to have caused the reaction.
Subsequent re exposure to TB 500 alone repeatedly reproduced the rapid heart rate response, although without the same severe hives/flushing seen during the original event. Most recent episode involved only 1.5 mg TB 500 and HR again jumped rapidly into the 140s before returning to baseline with deep breathing exercises.
Ipamorelin and tesamorelin have not yet been independently re tested, so they cannot be fully ruled out at this point. However, TB 500 currently appears to be the strongest suspect for the tachycardia component.
Unclear whether this represents:
- histamine release
- autonomic nervous system activation
- impurity/solvent issue
- anxiety amplification secondary to physiologic symptoms
- or some other mechanism
Curious whether anyone else has experienced elevated HR or allergic type reactions specifically tied to TB 500.
Not looking for medical advice. Just sharing data and interested in similar experiences.
